The DDAs have both purple and green phenotypes. As they age the leaves take on colour, especially if you let the temps drop at night. I didn't leave them that long as the night temps here are already down to 41 degrees, and I haven't started heating the studio space where they were yet. Here's a pic of the Sour Lowryder IIs that I grew alongside them. They gave me virtually nothing. Very disappointing, maybe 100 grams from three plants at most. Very colourful though.
