I must have neutral soil for these to bloom so purple. blue is acid, pink is alkaline. I think, anyway..it's got to do with the pH in the soil. That's good, I like the shade they are, it's a favorite color! I got these plants as leftover's from a mother's day display at work quite a few years ago. Recycling in all it's glory!
Some of my perennials in early bloom. Lots of budding going on in the greenery.
