      Planted two of these in hardscape last fall in my east-facing front yard and they over wintered beautifully. This is easily every visitor's favorite! It is so graceful and soft looking. I wanted to buy some as gifts for friends but, alas, HCG is out of them at the moment.

        Comments about High Country Gardens Nassella (Stipa) tenuissima:

        This is a beautiful and graceful ornamental grass. It grows well in the clay soil here in Northeastern Arizona. This grass seems to do well in the winters and summers here in the high desert/mountain country in the White Mountains. It does tend to get less green during the winters, but that changes during the springtime to a lush green. Doesn't take much water, and grows well.

          This plant is good for the area where I live which is high desert/mountain country. There is snow and rain during the winter/early spring season as well as rain during the summer monsoon season. This grass has survived both! So, I enjoy this plant in our garden.

              This is a lovely,soft,graceful grass.I bought it as an experiment as I live in New England and our weather is very different from the west/southwest.It did fine this summer,possibly because it was very hot and unusually dry this year.Now I'll have to see if it makes it through the winter;hope so,I really like this plant.

                I bought the Silky Thread Grass when it was available for sale in California. The Silky Thread Grass has grown into beautiful plants that reflect light and move beautifully when wind blown.

                I've had no problems with the Silky Thread Grass overtaking my yard either. I do live in the harsh high desert where there can be a 30 to 40 degree temperature difference between night and day. We also have nippy winters and hot summer days with wind.

                Recommend.

                  Always changing green(s) colors with seasons and weather type motions, always moving in slightest breeze...it produces its own alive-ness/3D of lush in depth layered green colors. It is the first thing you see and is a subliminal focal point.
                  Grows quick, its hardy, easy care, has an fountain type effect. Very glad I made the purchase!

                  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?

                  USDA Hardiness Planting Zones

                  To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

                  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
                  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
