This combines really well with Kanutia macedonica and Stipa tenuissima. The young growth looks like chives or baby leeks, providing great vertical accents even before the flower heads appear. When they do, they start to blush purple from the top down, eventually turning in to beautiful deep magenta drumsticks that look great with other perennials. Their seed heads are also beautiful, lasting in to early September, so the plant provides a long season of interest.
