Stipa gigantea

This is the giant straight species that is so popular for its soaring silver stems and golden drooping awns. To 12′ tall in bloom from a tight but large basal clump of fine deep green leaves. Perfectly evergreen with a great winter appearance. Very easy to grow grass that provides spectacular garden effects. Incredibly drought tolerant in any well drained soil- including clay if it is not allowed to become bone dry concrete. Flowers make a great see through “scrim” in gardens. Fun to grow. Moderate deer resistance.

Stipa gigantea ‘Little Giant’

As if a wonderful grass couldn’t get any better this smaller version thrills us with so many more applications. A low clump of arching dense dark green evergreen foliage has a nice presence year round. In spring and continuing all throughout summer into autumn 3′-4′ spikes terminate in clouds of metallic golden awns. They sparkle in full sun and sway in the breeze- but are determinedly upright. The basal clump of leaves spreads slowly to 2′ wide in 5 years. Full sun and well drained soil- bud adaptable to anything but a bog. Evergreen. Cut back spent flowers in winter- or let them stay and wave around beckoning birds and wildlife. Moderate deer resistance. Little to no summer water when established.
