Allium Purple Sensation and Allium Gladiator

I planted these last fall. This is my first year growing Alliums. I love them because they remind me of the Dr.Seuss trees :) I thought that the Gladiator would be fuller and more intense in color. It is a little taller than Purple Sensation and more pale. I also have planted Christophii but it is not blooming yet. I will post a video once it does.
