Chelle,
Maybe you could hit Garden Crossings as well as Romence? If you know anyone who has a plant license you can also get into Walters! Jennifer and I have made many "plant trips," but then, we are CRAZY! We were planning on doing that route when I go to Mi. in April but she cancelled out on me.
Everyone is ordering from places I never knew about so next year I am going to expand my horizons! I do limited plants though because I start most from seeds for economy.
I got a Spigelia Marilandica purely by accident on one of our local (Ann Arbor) trips and I didn't even know what it was. I brought it with me to GA, not knowing if it would survive but I uploaded a picture of what it looked like last spring to the database. I think it may be big enough to divide this year! Yay, but very nervous, I don't want to kill it. But now that I know where I can get another, not so scar
