As for any Asclepias, I think it would be useless to say more than: butterflies!
This species is tuberous, so no hope to divide it, needs to be grown from seeds. It has bright, crazy orange, umbels of flowers – hardy to be missed by anyone in the garden :)
Super-showy and super-valuable perennial plant(can I add ‘super’ a few more times?)
Germination: sown in late fall outdoors or in the spring after cold/moist stratification; it will take maybe 2-3 years to start flowering.
