PURPLE CHEETAH is one of my favorites. The color and the "splotching" are very attractive and give it distinction, IMHO. It does show a "cooler" look when photographed in the early AM. In my zone 6/7 garden, it has increased well and is a vigorous bloomer. I've only had it for three years. This one will be on the Stout Medal list soon, and will likely have a good shot to win that award.
Here are a couple of pics taken here at different times of the day. The first was taken very early AM, the second mid- morning, the last on a cooler morning .
