@Ageddd, Yes purple is good. If its in their genes it means they are reacting to the changes in weather and other signals of time running out to reproduce. Just like the trees in the fall except they have done reproducing long ago and they have shut off the supply of things like amino acids, sugars and carbohydrates to their extremities. While our plants do the same, they don't shut off the supply to the buds because they are still drastically trying to get pollen and make seeds. The hairs would normally grab the pollen and the seed would start. The resin helps attract insects and pollen clings to it so they keep producing it.
