Got Milkweed?

I’ve written before about my efforts to grow milkweed, not just because it’s one of my favorite wild edibles but because I would like to be part of the chain that helps the monarch butterfly survive. Monarch larvae can only survive on milkweed, and so for years I’ve been nursing along milkweed plants as if they were orchids, never eating any myself because I needed them to grow and spread and maybe offer a home for some monarch larvae. This year, six years after this project originally began, I saw adult monarchs fluttering around my blooming milkweed. I ran for my phone but couldn’t get a good picture, so I borrowed the one above.  It remains to be seen whether larvae will make their appearance, but I’m delirious with hope. If you have naturally occurring milkweed in your area, treat it like the resource it is. If you don’t, consider planting some seeds, with the understanding that it may be years before you see blooming plants. Do it for the monarchs, and one day there may be enough for you to eat some too.

 

Milkweed, For People and Others


People who live in wetter climates would be surprised, and probably amused, to learn what efforts I’ve made to have common weeds like nettles, burdock, chickweed, and milkweed grow on my property. Common milkweed, Asclepius syraica, has been especially difficult because it really does like moist soil and doesn’t tolerate “dry feet” or alkalinity gracefully.  It took a couple of tries before I got any to germinate, and now I finally have a few plants, which have to be watered and tended and fussed over as if they were orchids until they get stronger. I had to borrow photos because my own milkweed is still a bit on the spindly side.

One might well wonder why I bother. One reason is that I like to eat milkweed, especially the young seed pods, but the shoots and buds are just fine too. It’s a true nose-to-tail vegetable. Another is that I am transitioning from annual veggies to perennial wherever possible, and A. syraica is a good useful perennial that doesn’t require soil disturbance to grow. A third reason is that the flowers are fairly ornamental and send out a cloud of perfume reminiscent of flowery vanilla.

A fourth reason can be seen on this map:

Monarch migration

Notice how the sightings in New Mexico just peter out, while the ones in wetter areas east and west continue northward. Compare this to the maps on the same site for larvae and for milkweed. The migration of monarch butterflies from Mexico to the northern US is a migration of generations. The butterfly that arrives in Montana may be great-great-grandchild to the butterfly that flew north from Michoacon. All along the way they need breeding habitat, and their larvae feed on A. syraica and a couple of other closely related milkweed species. The leg of the journey through desert northern Mexico and southern New Mexico is a barren one, and a few milkweed oases along the way might help more monarchs make it to Colorado and further north. I can’t guarantee it, of course, but it seems worth a try. Adult monarchs will sip nectar from many flower species, but the fate of the larvae is tied to milkweed supply.

Since my plants are still too young to pick for eating, I won’t be writing about milkweed in the kitchen until next year, but you can obtain the two wonderful field guides by Samuel Thayer, The Forager’s Harvest and Nature’s Garden, and be prepared to forage and cook any common wild edible. I never tire of recommending Thayer’s books, which contain great detail about identification and culinary use at various stages.
