Butterfly Bushes

Several Butterfly Bushes are blooming in my backyard. The one above is called 'Black Knight' and is my largest plant. I really like the dark color.
The pink one is named 'Pink Delight' another pretty color.
The darker one above is 'Royal Red' sort of a red violet color. The sun was bright, so the picture doesn't look as dark as it really is.
I have a couple more in bloom, need to get a better picture of Ellen's Blue and Adonis Blue.
