Growing Palm Trees in Montana
Montana is a cold state. When I look at the map, I can’t even tell what area has zone 6a. Most areas of Montana lay in zones 3b and 4a making it way too cold to grow palm trees. The only way you can enjoy palm trees in your yard is to grow them indoors in the container and take them outside during summer. That way you will have palm trees in your garden for a few months out of a year. Some great indoor palms are:
- Areca Palm Tree – Zones 9a – 11 (20 to 25 F)
- Chinese Fan Palm Tree – Zones 8a – 11 (10 to 15 F)
- Kentia Palm Tree – Zones 9b – 11 (25 to 30 F)
- Lady Palm Tree – Zones 8b – 11 (15 to 20 F)
