Does anyone have knowledge of the survival rate for a Japanese maple in central Iowa. All the local nurseries say I would be wasting my money on a JM that is going to be located in the country. I have a protected spot on the south side of my house and would love to have one there, but with the expense involved I don't want to just throw money into a lost cause. Is there anything that I could do to improve its chances? Any advice on cultivar, etc. would be greatly appreciated.
