How much cold do you get where you live? Al

Well I live in NJ....I think that's zone 6 last I checked. If that helps.

Have you tried snapdragons? I have some mini's in a pot since last spring. They bloomed off/on all winter but I think our low was about 19 degrees.

Primroses or snapdragons bloom right through the winter here with average minimum lows at about 25 degrees. Al

Racking my brain more from when I lived in OH... Those primroses with the puckery leaves that are everywhere in stores in the early spring would be another good one, but hard to find in the fall.

Bergenia might be a candidate for you in a little more shade. They only flower in the spring, but the foliage is tough, turning dark red and staying "on" all winter.

The next-best things are the extremely early and late bloomers, and plants with interesting structures that remain above-ground through winter, like grasses and small shrubs with berries.

Have you checked out the winter forum? What about some flowers inside? Do you have a sunny windowsill for some wax Begonias?

Sorry, straying pretty far from seeds...

Have you considered Hellebores?
They bloom around February for me, absolutely stunning! And the foliage is great year round (with a little trimming)
