hi steve,seedsavers is fascinating and i like their catalog also.i emailed parks to let them know that the mimosa is an invasive species here,as much as kudzu,no reply yet.

This is another good seed site.

Lol
That reminds me that when I lived in Missouri my next door neighbor asked me if I wanted to plant some of the Kudzu seed she had bought to prevent errosion on the steep bank at the back of our lots.I managed to convince her not to plant them.
My next door neighbor here in Al. ordered some seeds for Hummingbird vines. When they came they were trumpet vines, which we used to call "Cow-itch" vines, her husband wouldn't let her plant them.

SHAME on Park's! With the thousands of different kinds of seed and plants that they sell, you'd think that they could be responsible!

I can't believe that any company, today, would still be allowed to sell Kudzu seed. I'm pretty sure that it is illegal to sell plants or seed, to plant the stuff, transport it, etc. anywhere in the US. (It's a Federally classified noxious weed.) I DO remember seeing it for sale many years ago, though. Yikes!

Heres a link to that wonderful add that offers y'all your very own mimosa
tree.

I don't think that Parks is selling kudzu, if that's what you thought, rhizo_1. But selling Mimosa and Empress trees is pretty downright despicable and they are definitely selling both of those.
