I planted a Crimson Gold in a container last spring. The leaves are a pretty green but no color. I brought it in for the winter and plan on taking it back out when it gets warmer. Do you think that would help with the color?
Lack of sunlight and over fertilizing can lead to loss of color variation.
Your plant should return to it's color patter of burgundy edged in gold when it returns to it's outdoor location. The variety can tolerate full sun in a cooler climate.
