I’ve seen some really impressive plantings of cosmos (Cosmos bipinnatus) but we’ve never had enough to really make a huge impression. Some years I think about getting a few packets of seeds but never seem to get around to it at the right time. This is from the ‘Sonata’ series and it a lovely color. They will self seed, if you’re lucky, and you’ll get repeat bloom from year to year, but we’ve only had an occasional plant from seed. Maybe next spring I’ll actually get my act together and put some seeds down. This and Nigella damascena (love-in-a-mist) are two that I think I could stand a lot more of.
