Dwarf live oak is a close cousin of the southern live oak, once named a variety of it, that never grows past shrub size. It grows on deep sand in pine flatwoods, sandhills and open scrub of the southeastern Coastal Plain, often beneath pines. North Carolina lists it as endangered, and NatureServe ranks it critically imperiled there and in Mississippi. It is an excellent groundcover that the nursery trade has overlooked. Use it as a woody groundcover on dry, sunny sand, or beneath longleaf pines in a restoration planting.

Size, growth and what to expect

Dwarf live oak grows slowly, and our growth estimator uses its slow class. Most stems stand under 3 feet, straight and often unbranched, and rarely reach 6 feet.

It flowers in early spring before the new leaves, from March to May, and it bears acorns every fall. A plant can fruit three years from seed, on a stem only 8 to 12 inches tall. The nut is five eighths of an inch to an inch long, up to half in a goblet-shaped cup. Its leaves come in two shapes, broad and coarsely toothed low on a shoot and narrow and smooth-edged near its tip. They stay green through winter until the new leaves push them off. Its acorns feed wildlife, and its leaves feed hairstreak caterpillars.

How to grow Dwarf Live Oak

Dwarf live oak wants full sun or light shade and a sandy, well-drained soil. Once rooted it needs no watering, but salt wind burns its leaves. In the wild it grows only where fire keeps taller plants back, so do not let shrubs shade it out. Set plants 3 feet apart for a groundcover, and keep each one 3 feet from a wall. It may grow within 15 feet of overhead wires.

Saplings ship bare-root or potted. Plant them from late fall to early spring, in a hole wider than the roots and no deeper. Set the crown at the soil line, put the sand back in, and keep the mulch thin. Live oak acorns sprout soon after they fall. Sow them on arrival, an inch deep, under hardware cloth.

Water every week or two through the first summer, then only in a long drought. Deer and rabbits browse young oaks, so cage the first plants for two years. The patch widens on its own from underground stems, so give it room to spread.

The flowers are wind pollinated, and an acorn crop wants another oak nearby. Dwarf live oak belongs to the white oak group, so its acorns ripen in a single season. Prune only in the dormant season, if at all. Where it meets Chapman oak along the east side of Florida, the two form hybrid swarms.

Heights and zones are typical ranges for the species in cultivation; local conditions and seed source shift them.
