I read in UT SP 517 for evergreens screens that nellie stevens hollies are a marginal tree selection for east TN. Is that a shared sentiment for those familiar with East TN? I am trying to find hollies that will eventually grow 15'+ with an upright shape. My list has fosters, nellie stevens, and savannah holly. I took off the blue hollies because I read they can have problems with root rot in this climate.
