Same old rule of thumb applies: If it's hardy in your zone, sow it now. If it's frost tender and killed by frost, wait till spring. Some folks do start tender stuff early, but then you have to worry about protecting seedlings if they sprout early. You just need to know whether the penstemons and salvias that you have are hardy in your zone.

Anything that doesn't tolerate frost, I don't sow until spring, around April in my zone.

Here's a pic of Penstemon Smallii that I wintersowed a few years ago. Hardy in my zone, they were sown in winter.
