Well yes, older cultivars have naturalized here (Sydney, Australia) you see them everywhere for a few weeks each year.
I just figured they'd take more than a year to flower from seed. Just interesting that many new ones bloomed this year that are distinctly different to what I planted. I'll be able to tell 100% next year, once a pod is ready I'll plant some seed in a pot away from the others and see if they flower in August.
