Blue-stem is a small fan palm with a trunk that remains below ground. Depending on age and growing conditions, the leaves can be anywhere from 1-5 ft (0.3-1.5 m) in length and width. The smooth petiole (leaf stem) is a little longer than the leaf. The inflorescence (cluster of flowers) is erect, extending well above the leaves. The fruits are black, about 1/2 in (1.3 cm) in diameter and their weight causes the flowering stalk to arch downward, sometimes to the ground. Also called dwarf or bush palmetto, the leaves of blue-stem differ from those of the similar-looking saw palmettoSerenoa repens in having a short midrib, an extension of the petiole and a smooth stem while the saw palmetto's is armed with small sharp spines that form the sawlike edges that give the plant its name.
Location
Light: Prefers partial sun and can tolerate light shade Moisture: Prefers moist soils but can tolerate drought Hardiness: Hardy in zones 8-10. Some varieties are hardy to Zone 7. Blue-stem palm is sometimes killed above ground by freezing weather, but re-sprouts the following spring. Propagation: By seed
Usage
Beautiful evergreen foliage makes a dramatic statement under tree canopies and other shady places. The Louisiana palm is an especially cold hardy variety of Sabal minor that has been grown as far north as Zone 7. There's another trunkless member of the Sabal species that is native to Florida called the scrub palm (Sabal etonia). Unlike the blue palm which prefers shadier sites and moister soils, the scrub palm grows on dry sandy soils often on hot sunny sites. Yet another shrubby palm native to the southeastern United States is the needle palm (Rhapidophyllum hystrix). Young specimens of these may resemble blue-stems but you can distinguish the two - dark needles emerging from the base of the plant show that it is a needle palm.
