24-28" x 24-30" wide (seed propagated). I found this beautiful hybrid specimen growing in northeastern New Mexico's San Miguel Co. an area of the state that can have extreme winter cold. The plant is exactly intermediate between its two parent species in both foliage and seed pod. Our plants are grown from seed of this single hybrid plant. I'm not sure how the seedlings will turn out at maturity but there will no doubt be some very pretty and distinctive plants. Zones 4-9. 3 deep Standard pot.
