When do you sow Rudbeckia seeds?
We are advised to sow perennial seeds first, then HA, HHA, and Annuals.
I'm trying to plan the WOW rudbeckia border. When I went to the Park Seeds site, I was confused by the descriptions of the seeds they offer:
Rudbeckia hirta Autumn Colors (Annual)
Rudbeckia hirta Cherokee Sunset (Annual)
Rudbeckia hirta Spotlight (Annual)
Rudbeckia hirta Cappuccino (Perennial)
Rudbeckia fulgida 'Goldsturm' (Perennial)
Rudbeckia hirta Denver Daisy (Perennial)
Rudbeckia hirta 'Ruby Gold' (Biennial)
Rudbeckia hirta 'Cherry Brandy' (HHA, grown as a biennial)
So, when do you sow Rudbeckia seeds? Do you WS now or later (since some are annual)
Does the decision depend on whether that variety is an annual, perennial, biennial, or a HHA grown as a biennial?
