Growing Palm Trees in Rhode Island
Rhode Island is too cold for palm trees. I has few areas in the zone 7a, but even cold hardy palms will have a hard time surviving the winter there. It is not only about how cold it gets, but also how long does the cold last. Many cold hardy palm trees can tolerate very cold weather but for a short period of time. Here are some palm trees that can grow in zone 7:
- Needle Palm Tree – Zones 5b-11 (-15 to -10F)
- European Fan Palm Tree – Zones 7b-11 (5 to 10 F)
- Pindo Palm Tree – Zones 7b-11 (5 to 10 F)
- Sago Palm Tree – Zones 7b-11 (5 to 10 F)
- Saw Palmetto Palm Tree – Zones 7a-11 (0 to 5 F)
- Windmill Palm Tree – Zones 7b-11 (5 to 10 F)
