Hi Ellen and C.L.!!
Guess what I’m doing today after listening? Sowing Bells of Ireland outside. Thank you for the tip!! I love green flowers.

Fantastic! Enjoy.
My green hydrangeas have turned white. I’ve heard upping the acid in the soil will turn them green again? Do you have any guidance?
What variety are they? Limelight and Annabelle both start out green but naturally turn white. Annabelle turns a soft green again as it ages. Some mopheads also turn white as they age. If this is what you’re talking about, there is no way to turn them back to green.
