Go for it, a pot will have 3-5 individual plugs which you will separate out and grow separately in other combinations, if I know you! There are lots more colors than what I pictured---there were SO MANY PHOTOS I just used a few. Look in plantfiles, or go to the nursery. Go for it! Thanks, Sally.
I have been growing them in pots in my Northern Virginia area for a couple of years. I love them. No deadheading, no sticky parts, lively colors...what's not to love? Prices this year seem a little lower than last year...more suppliers?
