Sabal minor Louisiana one of the hardier palms know surviving well in zone 7a – 6b. Sabal minors grow normally in swampy areas and can do well in garden settings. Large fan leaves will form as the plants grow to maturity. A large mature plant can reach up to 12 feet tall. Plants sold are seedlings in 4 inch pots 1 to 2 years old. My seeds came from a local source who has grown the plant here in Kentucky for 6 years with no protection.
