Growing Palm Trees in Rhode Island
While there are a few areas in Rhode Island that fall within zone 7a, even cold-hardy palms may struggle to survive the winter there. It’s not just about the cold temperatures but also the duration of cold spells.
Many cold-hardy palm trees can withstand very low temperatures but only for a short period of time, making them ill-suited for Rhode Island’s prolonged winter conditions. 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)
