Hi Kristen... A couple come to mind...

http://www.ediblelandscaping.com/
http://www.raintreenursery.com/
www.oikostreecrops.com/ (I ordered from them earlier this year and all plants are doing fine)

I would do some Googling for a nursery near you... but, definitely check out anyplace you're considering at Garden Watchdog. They rate many of the online nurseries. If you don't see them rated, then it could be because they a rip-off nursery and legally forced the GW to take down the bad ratings such as the dreaded TyTy nursery in GA. (Or it could be that they are just a little, unknown nursery). You can also search Google for the nursery name, and then the word "Scoop". Give it a try... Google "Raintree Nursery Scoop". It will give you "The scoop on 'Raintree Nursery'". Hope this helps.

The nicest blueberry bushes I have ordered were from Finch Nursery. Great prices too.
