Stipa tenuifolia

Stipa tenuifolia, commonly known as Mexican feather grass, is a graceful, clump-forming ornamental grass prized for its fine, hair-like foliage and airy, flowing texture

Also known as Nassella tenuissima or Stipa tenuissim, this perennial forms soft mounds of slender, bright green leaves that sway elegantly in the slightest breeze, creating a sense of movement and lightness in the garden.

It is still widely referenced in botanical and horticultural literature under its synonym Stipa tenuifolia, and has received the Royal Horticultural Society’s Award of Garden Merit under that name.

Regardless of the names that we have imposed upon it, this tall grass will create a beautiful dynamism and softness wherever she lives.

👨‍🌾 GARDENING TIPS👨‍🌾: Stipa tenuifolia

Floral Morphology

In late spring and early summer, Stipa tenuifolia produces narrow, feathery seed heads that catch the light, often shimmering like golden threads in the sun.

These flower plumes persist for weeks, gradually maturing to a subtle straw or beige tone, adding gentle, long-lasting interest well into autumn.

The plant’s texture and movement make it particularly effective in mixed borders, rock gardens, or naturalistic plantings, where it can contrast beautifully with bold-leaved perennials or colorful flowering plants.

Ecology

Stipa tenuifolia thrives in well-drained soil and prefers full sun, showing remarkable tolerance for drought once established.

It is hardy in a wide range of climates, making it a versatile and low-maintenance addition to ornamental landscapes.

Its light, flowing form also makes it an excellent choice for container plantings, patio accents, or as a border plant that softens hard edges.
