I checked on osage and it probably would not do good where I live because the soil is very rocky and the soil is very poor. It does look like a good choice for some people though. I will check with the county ag agent and state forestry division and confirm. Japanese barberry wouldn't look native because of the flowers and would likely make my place stick out like a sore thumb. Bamboo grows native here and wouldn't arouse suspicion neither would honey locust trees. I am open to more suggestions. I want my house to be completely hidden from the road and if you didn't know there was a house here I want people to pass right on by it.
