Stipa is found in temperate and warm-temperate areas across the globe. There are around 300 known species, spotted mainly in open woodlands and stony slopes.
An impressive ornamental grass that grows extremely fast in its comfort zone (Zones 8-10). Nice and tight shape that ends up being around 3' x 3'. By mid summer develops some of the most delicate flowing seed heads that you will see on an ornamental grass. These will turn a nice rusty orange above the bright green foliage in late summer and into the fall. An evergreen that can handle a cut back about every couple of years or so to refresh its look. A favorite for landscape designers and gardeners in general.

Sow seeds in spring, in containers in a cold frame (for protection and to ensure hardiness). Can also propagate by division in mid-spring to early summer.
Evergreen or deciduous, perennial grasses that are tufted and bristly. Stipas do well in the sun and plant height varies depending on species. One species of Stipa will grow to 3 ft. tall. S. arundinacea tolerates partial shade. Stipa works well in a mixed or shrub border. The inflorescences are suitable for cutting, and are often dyed to use as part of a flower ensemble.
Produces flattened spikelets with feathery awns between early summer and fall.
Irrigation needs vary depending on species. S. gigantea requires ample water until it is established. S. tenuissimus requires regular waterings. Does best in moderately fertile, medium-light soil with good drainage. S. arudinacea withstands heavy soils.
Deciduous species should be cut back in early winter. Dead leaves of evergreens should be clipped off in early spring.
Stipa is prone to brown stripe, eye spot, smut, brown patch, rust, and damping off.
