    I had seen this plant before on plant identification websites, but didn't think much of it. Then I saw the plant in person at a local native plant nursery, Landscape Alternatives, and I immediately had to get it. The leaves are so beautiful and silky, irresistible. I guess the beauty is hard to capture in a photo.
