Heart-Leaf Milkweed (Asclepias cordifolia) seed
Based on photos of this milkweed, posted to another thread by Mark (wildflowerman_2000), I purchased seed and would like to try growing this lovely milkweed.
I would love to hear from anyone having experience with Heart-Leaf Milkweed (Asclepias cordifolia) milkweed.
Should the seed be cold stratified and if so, for how long? I've kept the seed in the fridge but don't know how long to hold them before attempting to germinate. Since their native range is west coast and rather dry, I'm curious about the method of germination.
