Japanese Maples for zone 5--some confusion
I started out a couple of years ago putting in a Crimson Queen in my Japanese garden, and now it is doing great up in northern Illinois--north of Chicago. It is on the eastside of the yard and gets about three and half hours of afternoon sun, and an hour of dappled sun through a tree.
I took a break from tree planting last year due to a prolonged drought. This year I've been on a budget so I've planted a number of JM's that I got off ebay. The problem is some of the auctions label some as zone 5 and some label the same tree as zone 6. I am trying for at least two year old trees as I read on this forum about trying to get more established trees.
Specifically, Bloodgood is good to zone 5 on most sites but what about Red Dragon? I see it as zone 5 and sometimes zone 6. Chishio Improved I see as good to zone 5b on one website, but some as zone 6. Does anyone know of reliable zone info for a number of the lesser known types?
