I bought two butterfly bushes.. one pink and one blue/purple. The blue one has already bloomed and was very pretty. The pink one hasn't done anything yet..
But my question is, are the leaves on these supposed to be vibrant green? Cause some (several/alot) of mine are kind of a yellow-ish. I thought maybe I was over watering them.. do you know if they require very little water? They are still in the pots, not in the ground.. I can't decide where I want to put them.
And also, after the blooms are done, do I just leave them alone, or should I cut that part off? The blue ones that have already bloomed, the bloom part is a dark gray now.. not very pretty. So yeah.. any advice would be greatly appreciated!!
