Great topic Bobbie!
I love the idea of them being self deadheading - but I would want them to drop off during the night after they bloom. Then, they would probably pull off seedpods.
Years ago I did not deadhead. Now I HATE seeing all the spent blooms. So I usually "live head" in the evening. Much nicer picking the fresher flowers off instead of a lump of gross slimy stuff.
I would love to see really tiny ones with all the "stuff" larger ones have. I adore PENNY'S WORTH. It reblooms and reblooms here in Ohio. It grows great. I like the bloom size - I guess it is a bit smaller than a 50 cent piece. I think it is 10 inches tall. I wish the same plant came in all colors, patterns, shapes and sizes. With the little bitty ones, it is so easy to tuck them here or there, same as you would an annual. But, you don't have to do it every year!
