Some of the best known grasses are in this family but there are lots of others too. Drained soil in sun suits most of them. Many with fine airy foliage and flowers all summer.
Stipa is a family which is in the process of being revised somewhat so many familar Stipa are being (or have already been) moved to other families. If you can't find the Stipa you want here try searching (top right of the page) for : Anemanthele, Calamagrostis and Nasella. We haven't moved them all yet but will do so in time.
Many Stipa come from arid, open steppes and accordingly require full sun and well drained soil without too much fertility. The usualy cause of Stipa failing or flopping is too much moisture or food - or both!
A number of species will self-seed quite a bit but don't remove all of the seedlings as the parent plants will need to be replaced after a few years so having a ready supply of replacements is handy. Some species, like Stipa gigantea, tend not to seed much though they are also much longer lived.
