This will be my l0th year having Galaxy Explosion. It is a super plant. Makes a nice clump and is fertile both ways. Flowers are on the smaller size but still nice. The last 2 summers mine has rebloomed. It does well on hot days and scapes have never leaned for me, even though I get a lot of wind. Sets tons of pods and very good viable seed. It blooms for a long time for me. I also have one of its children Brushed By Bluebirds and that one is a super plant too.
