>> Seeds need to be harvested quite often because they fall out and/ or birds get them.
With most flowers, I know when to start snatching seeds becuase the heads or pods turn brown, but I didn't notice that happening with Salvias. I'll watch closer this year, and maybe just take one stem indoors, from each variety, every so often, and see what I can pick out of it.
Last summer was quite mild, and the Salvia that did well seemed to bloom continuously, though not profusely, all summer.
I forget if I listed the varieties that made it into the garden:
Salvia coccinea 'Lady In Red' (many, vigorous)
Salvia coccinea 'Coral Nymph' (several, vigourous)
A few each, not so vigorous:
S.nemerosasylvestris 'Amethyst Blue'
S. transylvanica 'Blue Spires'
Salvia superba 'Violet Queen'
Salvia nemorosa "Sensation Rose"
Salvia farinacea 'Victoria' (Parks or trade)
Salvia coccinea 'Forest Fire'
