Palm Trees in Nebraska
As should be obvious from the zone map, the vast majority of the state resides in 4b and 5a which are unreasonably cold for palm trees. Your only choice would be to have potted palm trees outside when it is warm, and then move them indoors before the first frost. Here are some extraordinary indoor/outdoor palms:
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)
