18" tall x 12" wide (seed propagated). Silky Thread Grass is our most graceful native bunch grass. It gently sways in the breeze and its silky seed heads glow brightly when they catch the sunlight. Plant Nassella in any well drained soil. It is an excellent xeric companion plant and is particularly nice when planted with Agave, Agastache and gray Artemisia. Re-seeds itself readily. Deadhead if you do not want volunteer seedlings next season. (Note, botanists have changed this plant's genus from Stipa to Nassella.) Not for sale in CA.

Comments about Nassella (Stipa) tenuissima:

Thriving, tripled size in 3 months, soft shaped-triangle shape. Loves NM weather; oven baking 120 degrees full summer sun, to the help-me-I'm-drowning monsoon season to the killing freeze winter temps in White Sands area. Still growing strong, increasing size and width, changes colors with seasons. Planted with potting mix, mixed in native clay soil, then mulched on top. I am looking forward to when it grows enough to "gallop" in the wind, looks good with Blonde Ambition sold here. Plants guaranteed,2 for 1 sale, every email answered quickly, the potting style and damage proof shipping/packaging is ingenious!!! How can you go wrong?
