Ecology and wildlife value
A fire-maintained flatwoods species and a genuine Florida endemic, used by monarchs and queens through the long southern season.
Monarchs are not the only thing that will find it. Expect large milkweed bugs on ripening pods, oleander aphids on the stems, red milkweed beetles at the flowers and, in late summer, milkweed tussock moths. Everything that lives on milkweed.
Growing feay’s milkweed
Occasionally offered by Florida native nurseries. Needs sand, sun and no irrigation. Fresh seed germinates without chilling.
Seed needs no cold stratification and can be sown fresh. Deep taproot, resents transplanting. See how to plant milkweed seed for the full method.
