This is another perennial I purchased this Spring from the Arboretum Sale for my new butterfly garden. I've never planted Allium before so I may be jumping the gun here saying that they are in bloom because ... looking at pictures online, they seem to have a globe shape flower and as you can see from my pictures, these guys look like they are just starting off.
Oh well, I still like the way they look mid-bloom.
I waited another week or so and now the blooms look fully open. Still gorgeous.
Allium Millennium so far is a petit flower and does very well against my patio and partnered with the Lesser Catmint. I have yet to see a butterfly in my butterfly garden however ...
