Local Swamp Milkweed
Asclepias incarnata var. pulchra
This is swamp milkweed grown from locally sourced seed -- the ecotype that evolved in our specific regional conditions, not collected from a distant population. That difference matters. Local ecotypes establish faster, bloom at the right time to match local monarch migration windows, and integrate with the local food web in ways that non-local plants can't fully replicate. The pink to rose-red flower clusters open in midsummer and carry a faint, sweet fragrance on warm days. As a monarch host plant, swamp milkweed is non-negotiable in any butterfly garden. Monarch caterpillars will strip the leaves and still come back for more. The fragrant pink blooms draw every milkweed-specialized bee in the neighborhood simultaneously. Plant this one near a window you look out of often -- the show will not disappoint.
