Stipa gigantea is an evergreen perennial grass with a tuft forming habit. Its foliage is narrow, linear and arching. In summer it carries elegant, open panicles composed of silvery, hermaphroditic spikelets, with long awns and dangling golden anthers and which persist into the summer.
Stipa gigantea, commonly known as Golden Oats or Giant Feather Grass, is native to western Europe including Spain, Portugal and Morocco and has been naturalised in the UK.
The etymological root of the binomial name Stipa is derived from the Greek, meaning ‘fiber’. Gigantea is derived from the Latin meaning ‘very large’.
Stipa gigantea may be useful to the landscape architect for its architectural habit and may be used as a part of a low maintenance prairie style scheme. The plant is also drought tolerant once established.
The Royal Horticultural Society gave Stipa gigantea their prestigious Award of Garden Merit in 1993.
Stipa gigantea will tolerate almost any soil conditions; it will be happy at neutral, alkaline or acid pH levels, in loam, sand, chalk or clay based soils facing any sheltered or exposed aspect.
Ecologically, Stipa gigantea will attract many species of small bird that will use its foliage both as material to build nests and as cover from predators.
Stipa gigantea requires little to no maintenance. Dead or damaged foliage and old flowered stems may be removed in spring. This plant may be propagated by dividing clumps from mid-spring to early summer.
