Arlene, thanks for starting this thread. Everyone's pictures are stunning, and such a treat to see at this wintry time of year.
I'll have to look at my plant combos next year to see if I have any accidental color echoes. I've been such a willy nilly gardener, just putting plants wherever without much thought.
The concept of color echoes is just brilliant, thanks to everyone for sharing their lovely pictures. This is definitely a thread to follow for great plant combo ideas.
