The shortest of the Ontario native Milkweed species that I’m offering this year, these mature to roughly 2’ in height. Like Common Milkweed, they are rhizomatous and will spread over time, rather than forming a dense clump.

While their foliage is quite distinct from many other Milkweeds, looking more like Liatris than Asclepias, it is still palatable to Monarch butterfly caterpillars

Please check out the Prairie Moon listing at the link above for more details.
