Bur Oak (Quercus macrocarpa) is a large-growing oak in the white oak group, producing low-tannin acorns that can be eaten with minimal soaking, or even raw if you don't mind a little tannic flavor.
These Bur Oak seedlings are grown from acorns collected from the current Montana State Champion Bur Oak.
These are 6 to 12 inch tall 1 year old seedlings in 1 gallon pots, 3 trees per pot.
