We usually plant a pot full of strawflowers. Strawflowers are really interesting flowers, because they feel like... well, straw. They're CRUNCHY! They have a hard look to them, and it's real. They make little crackly sounds when you touch them, or kinda squish them. Strawflowers love hot sun, but need lots of water in the early stages. Ours almost died once or twice, but they're pretty hardy
I think they're pretty, and the taller kind (ours are the dwarfs) make excellent cut flowers.
