Bloomed well all summer in our 90+ weather and is still blooming as the leaves are falling from the trees. It is described as upright and 15" tall, but I find it falls over so is more like 8."

Very pretty, light, airy, flowering plant - I really like this one! The one draw back on it is that it wants to spread itself everywhere - so since I don't want it to take over a whole garden I have to regularly tend to it.
