Ardisia escallonioides aka Marlberry

Ardisia escallonioides is an evergreen shrub or small tree called marlberry. Other names include marbleberry and dogberry. It belongs to the Primulaceae family. Its native range includes Florida, Mexico, Central America, and the Caribbean. Kew links it with wet tropical climates. In Florida, it grows alongside sabal palms and stoppers.

Garden plants often reach 12–15 feet (3.7–4.6 metres) tall. The broader listed range reaches 20 feet (6.1 metres). Plants spread 6–12 feet (1.8–3.7 metres) wide. The crown has an oval shape and a fairly even outline. Several trunks or clustered stems form much of its structure. The stems lack thorns, and new twigs are green. Removing lower branches can reveal the trunks and create a small tree. UF/IFAS rates growth as moderate, though its care notes describe faster growth.

The dark green leaves have a slight sheen. They stay green year-round, without a fall colour change. Each simple leaf has smooth edges and pinnate veins. Leaves grow alternately along the stems and have an oval shape. UF/IFAS gives differing lengths, from 3 to 8 inches overall. Small white flowers form dense panicles at the branch tips. These clusters reach about 5 inches long. The blooms have a pleasant scent but do not last long. Flowers appear at intervals across the year. Small, round, fleshy fruit appears in late spring. The source describes purple fruit in its overview and red fruit elsewhere. Each fruit measures less than half an inch across. Birds eat the fruit, which UF/IFAS also lists as edible for people. The evidence does not establish the safety of other parts.

Marlberry suits USDA hardiness zones 10–11. It grows in partial shade through full sun. Its foliage stays dense even with some shade. Give it soil that drains well. It accepts sand and loam across acidic and alkaline conditions. UF/IFAS rates its drought tolerance as moderate. Seed offers an easy way to raise new plants.

Use marlberry for hedges, screens, borders, or a single specimen. It also suits mixed groups and background planting near patios. Its dense growth can block views and frame other plants. Rows of small trees can line paths or entrance roads. The plant attracts butterflies as well as fruit-eating birds. Roots seldom cause problems, according to UF/IFAS. The same source reports no major pest or disease concerns. It does not identify marlberry as invasive.
