Another new line of hydrangeas is the "Halo" series. They were originally bred in Japan in the early 90s by Hiroshi Ebihara and later marketed in Europe as the "Frau" series. Now they are available here in the U.S. with names like "Angel Eyes" and "Angel Smile". We have "Angel's Lace" and it is quickly becoming one of our favorites.
Described as the first picoteed lacecap in the world (that is when the flower color has one basic color with a margin of another color), it is bred to be compact with sturdier limbs and larger flowers. It is marketed as being suitable for containers. It can grow to be 4 to 5 feet so it is certainly fine in the ground, as ours is. It is very hardy (to zone 6). So far, this has been a spectacular addition to the garden and one that I would highly recommend.
