We love the North American native ornamental grass, Nassella tenuissima! The airy texture is amazing, and it looks like an extra from the move Twister, even in the slightest breeze. Here’s a recent image from the gardens. It stops growing in summer, re-emerging when the worst of the heat has passed in fall. As you can see, it flowers for us in late spring. Hot sun, good air movement, and well-drained soils are the keys to success.
