I took these 2 leaf pullings off my 'Vigorous' VFT in late May. Obviously they are getting equal light, living in the same pot. So why so much differance in color?
I have frequently had variaton in the color of leaves on the same VFT. Some would be the deepest red, extending to the teeth, while others were a pink, or even remained green. Perhaps that is the case with your experience . . .
