Stipa or needle grass is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to Stipa, which have since been reclassified into new genera.
Many species are important forage crops. Several species such as Stipa brachytricha, S. arundinacea, S. splendens, S. calamagrostis, S. gigantea and S. pulchra are used as ornamental plants. One former species, esparto grass (Macrochloa tenacissima), is used for crafts and extensively in paper making.
This plant is a compact, evergreen ornamental grass. It has upright clumps of airy silver green foliage, topped with feathery flower heads in summer, and sways gently in the slightest breeze.

How to grow Stipa
Grow Stipa grasses in full sun and well drained soil. Comb through in spring or early summer to remove any dead growth. If the plant is flopping or beginning to look messy, cut back hard in late spring or early summer.
How to plant Stipa
Simply dig a hole the size of the root ball, drop the plant into it, firm in and water well. If you’re gardening on heavy soil, add a handful of horticultural grit or sand to the hole before planting.
If growing Stipa in a pot, make sure your chosen container has drainage holes at the bottom. Add some crocks at the base, then plant into peat-free multipurpose compost with some grit or perlite added to aid drainage.
Caring for Stipa
Stipa is an evergreen grass, so should not be cut back in late winter along with deciduous grasses such as Stipa gigantea. Instead, in April or May, comb through the grass with your fingers (wear gloves) or a rake to remove any old foliage or seed heads – the old growth should come away easily.
If your plants are beginning to look a bit messy or have got very wet in heavy rain, you can cut them back hard in late spring or early summer. They will soon regrow.
Stipa is drought tolerant when established, so there is no need to water your plant. Do not feed or mulch Stipa – it does best on poorer soils. Too rich a soil will encourage floppy growth.

Reproduction method is possible from the following methods :
- By sowing seeds : The time of sowing seeds of this plant is in spring and after the end of winter.
