Yes, and here's one of the WS FAQs to get you started.

Here is a link that might be useful: Spring & Summer Sowing FAQ

Thanks soooo much for the link seedmama! I am glad to hear because I started out late WS since I moved to a different state and didn't have to start back in Jan/Feb. Thanks again!

I spring and summer sow:

Asclepias
Sea Holly
Dianthus

All with great success.

The temps are getting up to the 70's & 80's now where I live. It still gets cooler at night, in the 40's. Should I consider myself to be spring sowing?

Donna, do you still need to wear a sweater at night? That's Trudi's test. I'm guessing you are into spring/summer sowing. Although I must say, it doesn't matter - just sow.

Because we have such mild winters here I summer sow all my pansies, violas, dianthus, sweet williams, and snapdragons and have sporadic bloom all winter and come early February they really take off and are gorgeous in March.....
