I love the texture of the leaves. Three of the four have been planted, so I can’t say how they’ll overwinter in zone 6B. Looking forward to the yellow fall color and the blue blooms of spring.

One lost most of its foliage within days of planting but did shoot up a new stem. Another one lost half of its foliage. One is still green . None have bloomed.

I bought two of these gallon size perennials as a visual reminder of my mom. They are doing very well. Having bought them at the end of May, after their blooming season, I can hardly wait to see them next spring. Proven Winners was great -- sending replacements because when I first received them, the delivery company had had them upside down and destroyed many of the stems/branches, Thank you PW!

Healthy looking and well shipped. Minor damage which should not affect growth. Waiting to see how it does over Winter and hopefully blooms in the Spring.
