The Stipa group of grasses are wide ranging and very useful for many garden aspects. They are a landscape gardener's dream plant. Garden Designers use Stipa grasses for their form, for their colour range, their differing heights and growth habits, and for their long periods of interest. From early summer through to mid winter.
Most of the Stipa range of grasses are perennial - some evergreen - but they all share a liking of an open aspect, and are rarely found in shade in natural habitats.
Stipa Ornamental Grasses are virtually trouble free, and needing very little - if any - care and maintenance. Sometimes referred to as Achnatherum - such as Achnatherum gigantea. We are happy with the more universally used Stipa.
They all have tufts of foliage from which the flower stems appear - erupt maybe! The deciduous Stipa will re-grow each spring. The evergreen forms, will have a somewhat untidy clump of foliage for the winter months.
All of the Stipa group are fast growing grasses - soon reaching their ultimate height and spread by mid summer. Just because these grasses are fast growing, does not mean they will take over the garden, they generally know their limit - and stick to it! Naturally they will increase in size (spread) each year., but will normally reach their ultimate height in year one.
Stipa are easy to propagate from seed sown in seed trays in mid spring. Being mostly perennials, they are very easy to divide, and this should be done in mid spring - just as the growth is starting. Divisions should flower in the first year if grown well.
There are no problems from either pests or disease for this group of grasses. All are fully hardy - especially if not waterlogged in the winter - down to minus 10 deg F.
