Are these able to be transplanted, they are in full sun and doing very well but can anyone say OVER SEEDED. I need to thin them out a bit but cant stand to kill them. I would be transplanting to pretty much full sun, maybe not early morning sun tho. So far what has bloomed are the same color, so they come in different colors? And will they come back every year or do I need to pull the head off and save for next year. I know nothing about these beauties.
