Just make sure you don't buy evodia seedlings (or anything else) from some scam artists at Wolfes Crossing Farms in Ohio.
I spoke to them on the phone, everything seemed fine, I sent my check, they cashed it, and when I eventually asked where the trees were I got a single, terse line that a killing frost came and that the trees showed no signs of life. My phone calls to them now go unanswered, as do my repeated e-mails asking for a refund. I have been thinking about getting some seedlings from a board member who posts here from Pennsylvania because I've heard decent things about him. Of course, I heard decent things about those unprofessional folks at Wolfes Crossing Farms, too.
