Cut Flowers

They are a tender perennial. So they would need starting indoors and once they have germinated they should be grown on undercover until the last of the frosts. Take the plants back under cover over the winter...pretty much what you would do with geraniums?

Though growing in a greenhouse all summer I'm sure you would get fabulous blooms.

I can't wait to start my asters - they also need a long growing season.

I would start now - I'm going to start a few perennial myself and I'm giving echinacea another go - I don't think it likes my soil much. But I love them.
