Ferula communis ssp. glauca is a Mediterranean native that makes a big, bodacious statement in the garden, first with its silvery-black, lacy, see-through foliage then, in the second season, the foliage extends upward to 6' tall, topped by a 3' branched, firework-like inflorescence of yellow flower balls. Ferula communis ssp. glauca dies after going to seed, so either administer a horticultural late-term abortion or you're going to have to tend to the babies without their momma.
