Does anyone know where I can find someone who sells yaupon holly bushes or a weeping yaupon holly tree?
For mail-order, check with Mail-Order Natives or Ecolage. They were both selling varieties of these and both have good reputations. What part of Tennessee are you in? Some local nurseries might have these.
Both are very common at most nurseries here in Knoxville. The weeping tree variety is especially nice and should be planted more!
