I'm not familiar with Ruby Grass, but of the others all can safely be planted now with the exception of Adenaphora, which you should wait to sow. Until like 2057.

Seriously.

I laughed out loud Jeanne (having spent the past 3 years trying to get rid of a patch.)Michelle, these lady bells are very invasive - proceed with caution.

The rest do look like great "do now" seeds.

LOL! But I should not be laughing.... I direct sowed some lady bell seeds last weekend into my shade garden. I'm totally screwed now, right?! Ugh.

I just googled adenophora. Now I know what that "weed" is that I've been pulling out of my gardens!

Michelle, this page on Ruby Grass may make winter sowing questionable - states germination is difficult and sporadic in a greenhouse - African native. Potentially a threat of naturalizing in Z9-Z11 so not a concern in that way for you there :)

Here is a link that might be useful: Ruby Grass

Just googled it, too. Don't do it. LOL. It just appears in my garden and it's very hard to get rid of. If I'm thinking of the right one, the stems break off and it's tough to get the roots.
