jocelyn, I can't say for sure how long it takes after it blooms - seems like it's several weeks. In this climate, NC, the cone
flowers blooms for a while. You certainly won't have trouble trading them on the
seed exchange forum though. Everyone loves cone
flowers.
Pianolady, I'm glad you posted that site. I've seen that on some of my
plants too. A wierd thing happened on one of my camellia bushes this past year too. It looked like magnolia leaves (sort of) grew on it in one area. I posted it in the mystery section. It was really strange.
