Stipa Tenuissima This low maintenance, hardy perennial is resilient and drought tolerant once established, seedling about freely to create fabulous wispy drifts. A fine choice for sunny borders, patio containers, gravel gardens or softening the edges of pathways. Grow Stipa on any fertile, well-drained soil in full sun. Avoid sites that sit wet in winter as Mexican Feathergrass can be prone to rotting in such conditions. Supplied as 1 x 3-litre potted Stipa Tenuissima plant.
