Butterfly gardeners, this is the biggest milkweed on the planet! A large shrub from tropical Asia, it has furry silver leaves and blooms lavender crown-shaped flowers. In Hawaii they're often used for leis.
This is quite a large plant, not just a garden flower. When fully grown, each tree can support
hundreds of monarch larvae. Happiest in zones 8-11, it will tolerate a brief frost but prefers
constant warmth. In cold zones, plant it in a large pot to overwinter indoors. It does fine
in a greenhouse.
Seeds germinate easily in a moist, sandy medium at 75* to 80* F. Like all milkweeds, the plant contain latex which is toxic.
These seeds don't come around often. Enjoy!
