Answer: Solanum rantonnetii is often called the potato tree. It's an evergreen shrub which can be trained into a tree form. As a shrub, it will grow 8'-12' tall and 6'-10' wide. Trained into a tree it will reach 12'-15' in height. The leaves are lance-shaped with scalloped edges. If your plants are Solanum rantonnetii, prune them back to keep them in shape (they're fast growing), provide full sunshine, and water deeply once each week. They're relatively easy to grow and established plants will come back if tops are killed back by frost. Enjoy!
