Eugenia involucrata (Cherry of the Rio Grande)

Eugenia involucrata, often known in horticultural trade as Eugenia aggregata, is a small to medium-sized tropical shrub or tree native to South America, producing glossy, leathery green leaves and attractive edible fruits. The fruits are typically rounded to slightly elongated, ripening from red to dark red or purplish red, with juicy, aromatic flesh that is mildly sweet to sweet-tart. The plant has ornamental value as well as fruiting interest and is suitable for warm gardens or large containers, where it can be kept compact with pruning.

Modern taxonomic treatments, including Kew/WCVP, place Eugenia calycina and Eugenia aggregata in synonymy with Eugenia involucrata, treating these plants within a single variable species. The name E. aggregata is retained here as the former horticultural name under which this plant has traditionally been sold. Our material typically has rounder fruits than Eugenia calycina, which is retained separately in the Top Tropicals catalog for the horticulturally distinct plant sold under that name.

Eugenia involucrata prefers full sun to light shade, well-drained but moisture-retentive soil, and regular watering during active growth. It tolerates light pruning and responds well to cultivation in containers. USDA Plant Hardiness Zones 9-11; established plants may tolerate brief light frost, but protection is recommended, especially for young specimens.
