The book ďHardy Palms for the SoutheastĒ writes that S. Minor prefers a moist, sunny location, and that an ideal situation for them is a bank of a creek or lake. And Odenwald and Turnerís classic text says: ďthe water table and soil moisture content have a major influence on plant size; the size varies with habitat: plants in lowlands are large and palmlike but are somewhat stunted in dry, open fields where they may not grow over two feet tallĒ.
So, Minors like the sun but also like moisture - a contradiction at most sites.
My neighborsís decision to take out mature trees in recent years has meant a lot more sun on my Minors. By providing them plenty of water (as I always had) the result is larger, leafier Minors for me, even for ones that have been in the ground for 10+ years. Interesting.
