A native perennial of choice, crimson milkweed attracts butterflies, is fragrant and produces magnificent umbels of flowers that are darker pink than the common species, asclepias syriaca. It also flowers a little later than the latter. It attracts pollinators as well as, of course, the monarch butterfly which chooses it as an egg-laying site so that the caterpillars can feed on it. We generally suggest cultivating it in a corner where we will take care to install a few honey-producing species as well as other species of milkweed.
Choose a location where the soil is cool, particularly humid and humic, hence its English name Swamp milkweed. It is therefore a good choice for a periodically wet environment, or on the edge of a pond and watercourse. Unlike the common species, it does not grow in dense colonies; it is necessary to provide companions preferring the same growing conditions when designing the layout.
This plant has some culinary potential. The First Nations used it as a deworming infusion, but you can also eat it, cooked, the young shoots, young leaves, flower buds and young fruits. Milkweeds in general contain a molecule, a glucoside, which is toxic in high doses. You should therefore consume little.
Sowing: Although we obtained a good germination rate without stratification for this milkweed, it is still advisable to stratify the seeds to maximize your chances. See our article on layering.
