Ferula communis subsp. glauca JCA

A greyer-green variant of this truly impressive giant perennial umbel from the Mediterranean with violet bloomed flower stems, forming big mounds of fine feathery grey-green foliage, and after a few years sending up a 3m stem topped with fat balls of slightly more mustard-yellow flowers. Full sun to slight shade. Summer dormant and fully hardy. This Jim Archibald collection has better colour in both stem and flower.
