Vivipary in flowers and other plants

My echinacea also doing it!

My rudbeckia are too! So much for collecting seed from them. I'll bury a few seed heads whole and see what comes up.

Yes I shall be doing the same. sounds much easier than buying seed, sowing seed, waiting for them to show and then pricking them out.
presumably they’ll be the same as the parent plant???anyone know?
mine are echinacea green twister which are pink and green (lovely!) so hoping that’s what I’ll get.
