My Plum Dandy Had Beautiful Purple Foliage And Was Growing Happily In A Container. But, The Purple Leaves Are No Longer Purple. T

Question

hey have turned green. Why?

Answer 1

Are they all green or just the new growth? When I look at photos of Plum Dandy, the new leaves look green and the older leaves are plum, as if they faded to plum.
Here are photos from a trial garden and the leaves seem to change colors. You might try giving yours more sun and see if that helps.
