Floaty, wispy, airy plants for full sun bed?

Hi all,
I’ve just finished my new bed and have put in some daisies, scabious, liatris, erigeron, vb, achillea etc in. It gets about 10 hours of sun and the soil is about 4 feet of loamy, free draining with added composted manure (below that is thick old clay you could make pots with).

I want some tall, floaty plants to give height but not be too dense. And also ones that can support themselves.
I’m gonna put some evergreens in too but that’s for another day.
Any ideas?
Thanks as always.

Mine flowers from june till frosts and needs no support.
I have The bride that I grew from seed and it flowered the same year and still going strong.
Dill would be eye-catching
