If I cut my wallflowers down after flowering, can I turn them into perennials?

Thanks. I knew there must be a reason. Seed is a good idea. I'll try that.

I find they're short lived perennials anyway Pansy. I have some that are flowering for the third time, and I let them set seed last year and the year before.
