The Siberian Elm and Our New Ecosystem

When I write about the uses of invasives, I can usually count on getting a lot of hate. So I’ll say this up front: I am thoroughly acquainted with the awful side of the Siberian Elm, Ulmus pumila. It invades inexorably, grows indefatigably, sucks up groundwater needed by our beautiful native cottonwoods, and is generally regarded as a trash tree. It’s changed the entire ecology of the Rio Grande bosque. I get all that.

But here’s the thing: while pamphlets and online sites are devoted to how to battle the Siberian elm, the battle is over and this tree has already won the war. It’s everywhere, and it cannot be eradicated.  So as I see it, we might as well look at whether we can use it well. And since I only write about my own small home ground, I am not looking at how to use hundreds of acres of it well, but how to use it on a half acre.  It grows lustily even in our dry desert climate, and there are large areas where it is the only green thing around, so I feel a certain gratitude to it. But I don’t allow it inside my yard because I want other trees there, and because as soon as I step outside my gate, it’s everywhere.

For me, its food uses are limited. I’ve written before about the edible samaras, or seed cases,  and I won’t say more here except that they have a pleasant green mild taste and are produced in unbelievable quantities every spring, and the chickens like them as much as I do.  As I get further into permaculture I’m experimenting more with tree leaves that have culinary uses, but I can’t find anything much about Siberian elm leaves except on the wonderful site Eat the Weeds, where I find that the young leaves are edible cooked. I admit that this doesn’t sound enterprising on my part, but I haven’t tried it yet. I have so many other green things to eat that it will probably be some time before I make this experiment.  I can’t find any nutritional analysis even about their use as fodder, although I did find one reference stating that they might be a potential source of higher-protein forage for animals.

But when it comes to nutritious forage, I typically let my beloved old dairy goat Magnolia make her own decisions. And there is no question that Siberian elm is her favorite food and one of the few foods that she never gets tired of.  So over the years I have been letting Siberian elms grow up along my longest fenceline, and cutting them back above the top of the fence. New branches grow at astounding speed below the cuts, and Maggie chows them down as an almost exclusive diet all summer long. She is naturally on the thin side, but loses no weight during the 6-7 months of her elm diet, and her enthusiasm never fails. The usual life-span of a domestic goat is 9-11 years and she is pushing 13, so I don’t think it’s done her a bit of harm. The feed is free, as local as it gets, and gives me plenty of mostly unwanted exercise with the cutting and hauling. The trunks occupy the space along the hot baking hell of the open space, and I don’t give them any water so they’re surviving on what they can find on their own. There’s no doubt that they look scraggly between cuttings, but I can tolerate that to see Maggie so happy. And if I ever get hungry enough I’ll try eating them myself.

The hens also love the leaves when young and tender. They might eat the tougher late summer leaves if cut up, but I don’t bother when there are so many other greens for them.

I’m largely talking about animal feed here, but whenever I allude to possible human uses I feel compelled to say a few common-sense things about wild and unfamiliar foods:

1. Never assume that because an animal can eat it, you can eat it. Goats in particular are able to eat some plants that are toxic to other animals including humans. Magnolia’s metabolism is wired differently than mine.

2. Never assume that because one part is edible, the whole plant is edible. Black locust blossoms and elder flowers are delicious, but the leaves and stems are toxic. There is no substitute for studying reliable authorities.

3. Never assume that because other people including reliable authorities can eat it, you can eat it. Test a small amount of any new food, and wait a day before trying more.

A Quick Note on Bamboo

I love bamboo shoots, and several years ago I bought two plants of Phyllostachys dulcis, the famously invasive and delicious sweetshoot bamboo. I enriched the soil, planted and mulched, supplied plenty of water, and waited confidently for them to invade, so that I could start eating. Four years later the two plants are a scraggly 5’ tall each. Each year one or the other, but not both, makes exactly one spindly shoot which often follows a kamikaze trajectory toward the goat paddock.   In all this time, I have eaten exactly one bamboo shoot. It was very good, but a pretty poor return on investment.

This May, after a few days of absence from the garden, I was looking along the fence row inspecting hops vines  when outside my fence, in the desert open space, I saw a startlingly robust bamboo shoot almost 20 feet tall.  Phyllostachys dulcis is spreading out into an area that is impacted, alkaline, and gets only our natural rainfall, which is 10 to 11 inches per year.  In short, it is a bamboo’s version of Hell, and yet this is where my expensive and pampered plants have chosen to stake their claim.

Plants are naturally perverse, and the more you want a particular plant to flourish, the more perverse it typically becomes.  It is as if they thumb their noses at the whole concept of domestication.  But next spring I will watch the desert strip outside the fence and see if the miracle repeats itself. If so, I may finally harvest enough bamboo shoots to be worthwhile.  If it finally begins to behave like a real invasive, I can always take my goat out on a leash to teach P. dulcis some manners.

I should add that if you don’t live in the desert, you can’t afford to be cavalier about invasive plants. Be aware of your neighbors, don’t invade their space unintentionally, and if you plant an invasive bamboo you really need to create proper rhizome barriers. My P. dulcis  plants have a foraging goat between them and any neighbors, and the part of the open space they are growing into actually belongs to my property. I doubt that they can get far on 11” of water annually, but if they show truly invasive behavior out there I have room to make a concrete barrier.  I have never seen a bamboo get out of hand here in the desert, and don’t anticipate it happening now, but I’ll act assertively if it does.

The Greens of Early Summer

I love leafy greens and consider them one of the healthiest foods in the world, as long as they were raised in a clean fashion.  If you are lucky enough to have a garden and an active permaculture property, you can nearly always eat some greens but the source of your greens changes throughout the growing season.  Right now, we are in the glory season for lambsquarters, and they are everywhere and are at their tender best right now. I eat huge quantities of them, but I have written so much about them elsewhere that in this post I will say very little except: for the sake of your health and your palate, learn to identify them, harvest them, prepare them, and eat them.

Today I decided to write about some uncommon greens which are unique to the season.  Americans don’t think very much about eating the leaves of trees, but some of them are very appealing, and my favorite “tree green“ is the young sprouts of mulberry trees.  It is almost never possible to gather good edible leaves from mature trees. The best mulberry greens are the tips of actively growing shoots from trees that have been cut back, and I am lucky because on the walking trail near the river in my area, several mulberry trees have been cut back to keep them from impinging on the trail. They produce a forest of new growth, and it is the tips of that new growth that are good to eat.   Harvest only as far down as the stem can easily be snapped with your fingernail. If it bends or creases instead of snapping, go further up toward the tip.

Incidentally, there is some pretty ridiculous stuff on the Internet to the effect that mulberry leaves will get you high or the water from cooking them will. Utter rot.  This is one of those unfortunate cases of one writer printing a piece of misinformation and dozens of others picking it up as gospel.  I have been eating young mulberry tips for decades, and nothing remotely interesting has ever happened as a result. Euell Gibbons ate them, Samuel Thayer eats them,they are used as a tea throughout Southeast Asia,  and there is no reliable report anywhere of them causing hallucinations. You must always do your own due diligence and make your own decisions, but I simply don’t worry about it.

For a quick lunch for two, I gathered a double handful of mulberry tips. I washed them and cut them in fine cross sections of less than a quarter inch, chopping a large bunch at a time.     Then I considered what else to add.

I could’ve used sorrel for a tart element, but since the leaves on my petit syrah grapevine are young and tender, I decided on several of them.  Wash them, stack them, roll them up like a cigar, and sliver them very thin with a sharp knife.

For flavoring, garlic is always a favorite of mine, and right now the garlic is forming bulbs but they are small and the skin is still young and tender. I pulled an entire head since they are mild this early, peeled off just the toughest outer layers, and sliced the rest finely in cross section and chopped it. The material that would later become the skins is full of allicin, and is very desirable.  But I also wanted some herbal flavor, so I grabbed the top of one of my bronze fennel plants. At this time of year, when it is getting full and bushy, bronze fennel is so ornamental that I can hardly stand to use it, but it tastes good so I try to overcome my scruples.

I decided that I wanted a texture element, and this time of year my favorite crisp texture is the scapes of last year‘s leek plants.

Cut them before the bulb on top begins to open, peel off the very tough outer skin, and then use a vegetable peeler to get all stringy bits off.

As I got ready to cook,  I decided to cut the stalks in quarter inch  cross sections because it would go better with the other textures. The taste of leek stalks is soft, oniony, and sweet.

First heat a skillet over medium heat.  Then add your oil of choice. I used a mixture of olive and avocado oil.  When the oil is hot, put in the chopped garlic, leek stalk pieces, and fennel.  Sauté until the garlic looks cooked. Add the chopped mulberry leaves and grape leaves, and because the texture of mulberry leaves tends to be dry, I added a quarter cup of water at this time.  Add salt to taste, and sauté until the greens are cooked to your liking and any added water is cooked away but the greens aren’t too dry. Personally, I like tree greens a bit on the done side, since they tend to be a bit chewy when cooked al dente.   Taste for seasoning, and then set your greens mixture aside in a bowl, reheat the skillet, put in a knob of butter, and scramble whatever you think is the right number of eggs for two people.  When cooking for my husband and myself, I always use a mixture of three eggs and three additional egg yolks, beaten together with about a tablespoon of cream.  When the eggs are scrambled and have less than a minute left to cook, return the greens to the pan and stir the mixture up together, but you want discrete lumps of egg to remain among the greens.   Serve onto plates, grind over fresh pepper to taste, and salt as needed.

Besides mulberry and  grape leaves, I’m giving thought to other climbing perennials or trees that might be useful for greens.  I have a linden tree that I planted specifically for greens, however the texture turned out to be somewhat mucilaginous and if there is one thing I dislike, it is what my husband calls the “mucoid food group.“  They are fine in a salad when young, but I don’t care for them cooked at all.  I am beginning to eye the shoot tips on Siberian elm trees that have been cut back. My goat and chickens eat them in huge quantities, and maybe I could too,  so I have been searching for data, especially because this is an enormously prolific trash tree in my area.  According to the website Eat the Weeds, run by the prolific and reliable Green Deane, the very young leaves of both Siberian elms and Chinese elms are edible and can be used interchangeably with each other. So I will be trying that in the future. I’ll report back.

Passing pleasures: Hops shoots

Many years ago I planted hops vines along my fences, planning to use the flowers for brewing. Not long afterwards, I gave up beer for weighty reasons, but in my difficult climate I’m not likely to get rid of plants that grow lustily with no attention. There was also the delightful bonus of hops shoots every spring. Gather the young shoots by snapping them off at the point where they snap easily. This is usually about the terminal 6-7 inches of the vine.

When it comes to cooking them, I’m very opinionated. After trying other ways, I’m convinced that this way suits their rich-bitter flavor best. Rinse the bundle of shoots and cut them in cross section, 1.5-2 inches long. Heat a large skillet over medium-high heat. You don’t want to crowd the pan too much. A 12” skillet is right for one large bundle of shoots.  When the pan is hot through, add a glug of good olive oil, swirl it around, and add the shoots. Toss them around, sprinkling them with a good pinch of salt. Toss the shoots every couple of minutes.

Here’s the part that many find difficult. When they look like this, keep going. Taste them at this stage and, if you like them you can stop here, but I think that you haven’t yet tasted hops shoots at their best. Instead add a pat of butter, at least a tablespoon, and keep cooking.The butter will brown a bit and is important to the flavor.

This stage, in my opinion, is their point of perfection. They have shrunk considerably. The stems are browned in spots and many of the little leaves are brown and crisp. Taste for salt and serve. I find them delicious. They are especially good alongside ham or bacon, and I like them with fried eggs for lunch.

Hops plants are known to contain an estrogenic compound and chalcones. The latter are an interesting group of chemicals with anti-tumor properties, and you can read more about them here. What this means in practice is anybody’s guess, and my own opinion is that it means very little, since the shoots are only in season for about 3 weeks and no one person will eat enough of them to make much difference one way or another. They are a springtime gift of the earth, thrown up exuberantly in great quantities with no effort on the gardener’s part except providing them with something to climb on, and I cherish them as such.

If you plan to grow them, remember that hops are intent on world domination and need a sturdy support. Also, they spread and come up in unexpected places. This is fine with me, since I keep a very untidy yard anyway, but if you like things to stay neatly in their assigned places, the bold independent nature of hops may not be to your taste.

A Quickie on Soil, and notes on quixotic planting

In the area of my property called the Perennial Paddock,  I have been doing a deep mulch for about six years, undisturbed except for topping it up with straw and pulling some of the worst perennial weeds.  When I can hire help to dig the waste alfalfa and manure out of the animal paddock, it goes on this mulch. The result, to my intense delight, is that where previously I had compacted clay and tumbleweed, now I have dark black soil about 12 inches deep.  This area has allowed me to observe that if you have time for the soil to build itself, and keep an endless supply of mulch to spread as needed, you do not really need to do any other soil amendment. You also don’t need to correct pH or any of the other maneuvers commonly recommended for soil improvement.  The year that I started mulching this area I invested in a bag of Thorvin kelp meal and spread that around, and since then all I have added is the straw and animal bedding. Lots of it. More than seems to make any sense when it’s dry and fluffy, but it will pack down to a surprisingly thin layer and have to be topped up a few times a season.

The first thing I ever planted here, way back before it was mulched, was a black locust tree. The little twig is now about 40 feet high, and when it is covered with blossoms in April, the entire tree through arms with bees.  It provides shade, and I think its  widespreading roots are part of what has broken up the soil so thoroughly.  In other areas of my yard I have actually had to break up hard packed areas with a pick, but in this paddock the locust tree has done all the hard work for me.

Now it is the matriarch of a wildly varied colony of perennials, and because of the soil quality and moisture level, this is also the place where I experiment with difficult plants. Oca, for example.  This member of the oxalis family is a sharp-tasting tuber available in a wild variety of colors.  It is native to the high Andes, and a sensible person would realize that it does not want to live in my flat baking high desert area with its  brutal summers.  But it is so pretty that I can never resist buying 15 or 20 tubers and experimenting.  So far I have tried them in a garden bed and in a berry row. In both locations, they grew until about July, then withered and died back, and the tubers that they produced were about the size of a pea or smaller rather than 1-2 inches long as they should be.

This year I ordered my usual optimistic packet of tubers, and decided to plant them almost directly in the shade of the black locust tree, in the deep cool soil that now exists there.

It will occur to the reasonable  economist that at this point I have spent a total of about $70 on tubers, and have not yet reaped any return.  But no garden is entirely reasonable.  If I were only going to grow things that “pencil out,“ I would do fine to just let my entire property come up in lambsquarters, which cost nothing to plant and give an effortless harvest of nutritious greens.  But I feel that I would be worse off for having missed the joyous expectation of putting beautiful little earth-jewels in the ground and hoping for them to multiply.  If I get enough to harvest, I don’t even know if I will like them, since I have never had a chance to taste them. But I’m not sure how much it matters. Hope is the point.

I get my oca tubers from Cultivariable, a fascinating source for little known Andean food plants.  They are usually sold out of the choicest selections by late February, so bookmark them for a look next winter.  I have read that oca foliage is also edible, so this might be a nose to tail perennial, but I don’t know yet.

Permaculture Salad

It occurred to me this morning that my lettuce won’t be ready for weeks but there’s no problem at all in filling the daily salad bowl. After years of practicing semi-permaculture  and using the results in the kitchen I have strong opinions about salad greens, so I thought it might be worthwhile to go through the ones that I use most.

Major greens: these make up the bulk of the salad.

The picture above is blue mustard, one of my very favorites. It makes up about half of the bulk of any salad in our household this time of year.  I wrote about it at more length in my previous post, so what I will say here is that it is a recent invader in my area.  It first showed up along the ditch banks about four years ago, and now it is a common “weed“ in my yard.  I have no idea where it came from, but I’m glad it’s here.  Get it young, before you notice the tiny blue blooms, and I usually harvest with scissors, cutting about 2 inches off the top of the thick clumps.

The second bulk green right now is scorzonera.  I have written about it elsewhere, so all I will say here is that although it is often grown for the root, I find the root not worth the trouble, but the spring leaves are mild,crunchy, tender, and excellent to make up the majority of the salad mix.  The bloomscapes that come up a little later, harvested before the buds swell too much, are among my very favorite vegetables, so at this stage I harvest individual leaves to make sure I don’t hurt any potential scapes. Take the wider upper half of the leaf,  and leave the long stringy stem bit where it is.

it takes a few years for scorzonera to establish and make nice full clumps. I advise against cutting it at all the first or second year.

My third bulk green right now is bladder campion.  It took me a few years to get this one established, but now it is a thriving weed and comes up everywhere. The roots are deep and tenacious, so be sure to pull the roots out if you do want to get rid of it.  I pull it out of my raised beds but let it romp away everywhere else. Cut off the top 2” and discard any bare stems.   During the summer it is weedy and flops all over other plants, to their detriment, so you have to whack at it a bit. But it is always my first green of spring and the last one of fall,  so I would never want to be without it. I have heard the taste of the young sprigs described as “exactly like green peas.” I beg to differ. They do have a hint of green-pea flavor but they aren’t sweet and do have an undertone of faint bitterness. I find them delicious, and they are mild enough to go with anything else.

Minor greens:delicious when used in smaller quantities.

Sow thistle has thick leaves with an intensely green flavor. In some soils I’m told that it’s bitter at all stages, but in my yard it’s mild when young. I don’t have much of it, but enjoy what I have.

Arugula has been allowed to self-seed in my yard for so long that it’s now a common weed. I throw leaves in the rosette stage into salad, and any that get past me produce small white flowers that bees adore.

Alfalfa is nobody’s idea of an edible, apparently, but I like a couple of sprigs per serving. I pinch off the top rosette when the first shoots are about 4” high. Only the first growth of early spring is suitable for this use, and no stems.

Oxeye daisy delights the bees when it blooms, and the earliest spring shoots delight me in salads. They are tender, sprightly, and vaguely sorrel-like in flavor. I would eat a lot more of them if I had more. I’m putting in a larger patch this spring.

I use dandelions in limited amounts, maybe 10% of the total salad, but I miss them when they aren’t there. Once or twice a season I eat a big salad of pure dandy greens with a garlicky dressing and a side of bacon, but I don’t often have the materials available. Believe it or not, dandelions aren’t common in my area, and the eight plants that I have were started from seed and fussed over like orchids. I let them go to seed, and hope that eventually my yard will be colonized and I can eat dandy salads whenever I crave them.

Pea greens are a delicious tender green that really does taste like green peas. I plant my peas very thickly, almost touching in the furrow, and then harvest about half for spring salads, leaving the rest to grow and bear.

Seasonings: these have more distinctive flavors. Don’t be too timid with them though, because the dressing is going to mute them quite a bit.

I grow the sorrel variety called “Perpetual,” which doesn’t go to seed. It has the zingy lemony taste of garden sorrel but has thicker, more tender leaves and is a much smaller, less robust plant. I definitely need more plants of this one.

I grow parsley in a semi-permaculture fashion. Planted in spring, I use it all summer and leave it in place in winter. The following spring I get lovely bunches of early leaves to chop over salad and other stuff, and then it shoots to seed and reseeds itself.

This photo has three of my favorites. To the right are perennial green onions, which I have written about so much that here I’ll just remind you to sliver some into salads. In the center are young shoots of bronze fennel. Later in the year I would chop them up, but at this stage they’re so mild that I just cut each small leaf in 2-3 pieces. To the left is the first spring growth of Angelica archangelica, which I haven’t used until this year. The first tender leaves of spring have strong notes of celery and juniper. I tear them into pieces about an inch across. When they start to get tough, the stems chopped in thin cross-section will give a similar effect.

The earliest shoots of French Tarragon add a lovely anise flavor. I pull the new sprigs into individual leaves and toss them in whole.

I have heard people say that each dish or salad should contain only one herb, so as not to “muddy” the flavors. I couldn’t disagree more, and have seldom made a spring salad that didn’t contain at least three. Chopped finely the flavors can muddle up and become undistinguished, but left in large distinct pieces as I use them, they are vivid and impressionistic on the tongue.

 

Spring Alliums

Green onions and green garlic are always the first food to show up in my yard. My onions are the Egyptian and produce hugely with no input from me. In fact, they are becoming a weed in places and need to be dug out. But I would hate to be without them.

Green garlic of the ultra-early Chinese Pink variety is ready at about the same time. I plant plenty the previous fall and plan to eat most of it green, on grounds that I can always buy organic garlic bulbs if needed but can’t get good green garlic anywhere but my own yard.  Most of the green garlic that I have seen in stores and farmers market has been overly mature and well past its best. When it is young and tender, you can eat everything up to the leaf tips. Just peel off the lowest leaf and the outside layer of the stalk and you are ready to go.

Green onions and green garlic can be cooked the same way, and I  usually cook them together. Slice the stalks in quarter inch cross section and sauté them with a little salt and butter or olive oil for about five minutes, add the leaves also sliced in quarter inch cross section, and sauté until the leaves are tender and done. Taste for salt, and you can eat your allium mix as is or add it to other dishes. It’s good with scrambled eggs or in an omelet with a little cheese, and makes a good side dish for many, if not most, main dishes. It’s great on pita with  some pan-grilled halloumi. It can be the basis for a horta of mixed greens. It’s full of allicin and other benefits, but I make it because it tastes good.
