Here is a toad’s eye view of my woodland rock garden. In it from top to bottom is Lily-of the-Valley, Periwinkle, Phedimus Spurius, and Partridge berry.
@maggiemae Thank you! :) This is the way it’s growing. The rock garden is made in back and on top of a stone wall. By summer the plants will vine down over it & you were right, the blue is the Periwinkle :)
