I was pleasantly surprised by Trahlyta, and have come to love it in my garden. I wasn't sure how I'd feel about the grey-ish tint on the blooms, but it is so unusual, and lovely, and changes throughout both the day and the season. I was increasingly intrigued every time a bud opened. It does well here in my Zone 4 garden, reaching about 28" high with 6" blooms.
