In our opinion, Stipa barbata Silverfeather is one of the most beautiful of all grasses, but also one of the slowest growing. It may take several years before it gets to a decent size but well worth the wait. Forming a dense clump of foliage to about 1m tall, the excitement comes in June and July when it forms its dramatic feather-like awns. The extremely long silvery silky plumes are held horizontally and they wave and undulate in the slightest breeze. A higher price than most grasses as it is difficult to collect the seeds before they fly away!
