Raising Milkweed from Seed is Easier than You Think
Butterfly Weed, Swamp, Poke Milkweed
Don't be intimidated by the term stratifying. Stratifying native plant seed is nothing more than, “tricking” seed into believing it is
time to rev up their engines and start growing. Plants that are native to Ohio
have a built in “safety mechanism", which prevents them from starting the
germination process until conditions are optimal, length of daylight and ground
temperature are a few of the ways seeds receive their "signal" that
spring has arrived. If species like Asclepias (milkweed) are duped in to believing spring
was right around the corner during the first January thaw their seedling
survival rate would certainly plummet.
