I have two. The first is Border Lord. My mother bought it for me many years ago and it gets prettier each year. The pictures below show the difference for full sun and partial shade also.
I wasn't completely hooked until I was at a nursery and saw Ruby Spider...I knew I had to have it. I bought one pot to take home and couldn't stop admiring it.
The nursery had it for half price weeks later, so I bought three more
