Perennials: Some Rudbeckia , 1 by jmorth

This year's crop of Rudbeckia are all either self-seeded or possibly over-wintered. Usually a few survive the winter but most succumb to heaving due to temperature variability. I let the flower heads mature naturally and inevitability seem to get a bumper crop of seedlings therefrom each spring (often it's necessary to thin some out). Each year the resultant offspring present unique characteristics from natural crosses that happened the previous season.
