Mexican Feather Grass (Stipa tenuissima / Nassella tenuissima) - 1000 Seeds - Bulk

Mexican Feather Grass, botanically known as Nassella tenuissima and widely known under its former botanical name Stipa tenuissima, is a fine-textured perennial ornamental grass valued for its exceptionally slender foliage and soft, flowing appearance.

Plants form graceful clumps of narrow, thread-like green foliage topped by delicate, feathery flower panicles. The foliage and seed heads move readily in the wind, creating the characteristic soft, flowing effect that has made Mexican Feather Grass popular in contemporary, Mediterranean-style, and naturalistic landscapes.

This species develops a clumping bunchgrass habit rather than spreading through underground rhizomes. It performs particularly well in sunny locations with well-draining soil and is well adapted to relatively dry conditions once established.

Cultivation and Use

Mexican Feather Grass is valued for its extremely fine foliage, graceful movement, and soft ornamental texture. It is particularly effective in mass plantings, borders, rock gardens, containers, and naturalistic or drought-conscious landscape designs.

Seeds can be sown in a well-draining propagation medium and maintained with consistent moisture during germination and early establishment. Once established, plants are relatively drought tolerant and perform best where the soil is allowed to drain freely.

Mexican Feather Grass can self-seed readily under favorable conditions. Because Nassella tenuissima is considered invasive or regulated in some areas, growers and purchasers should check applicable state and local regulations before purchasing, propagating, or planting.
