I now know that Cosmos do not float well!
With very short and curvy stems it was impossible to get these Cosmos and Scabiosa to stand up in a vase, so I decided to try floating them… well, the Scabiosa and pale blue Didiscus, along with a Clematis seed head, all floated nicely, but the Cosmos submerged almost immediately.
Nevertheless, pretty for a day or two, and now I know!
