About Robin Holly
Robin Holly (Ilex × attenuata 'Robin') is a dense, upright evergreen holly — a female hybrid of Ilex cassine and Ilex opaca — selected for its compact, pyramidal form and abundant bright red berries that ripen in fall and persist through winter. The glossy, lightly spined foliage provides year-round appeal, and the heavy fruit crop makes it a favorite for birds. A compatible male holly pollinator is required for fruit set. Starting at $275.00.

Care essentials
Light
Robin Holly thrives in full sun to partial shade. Full sun produces the densest growth and heaviest berry crop. In NE Florida, a site with morning sun and some afternoon shade suits the plant well in summer.
Water
Water regularly during establishment (first 1–2 seasons); once established, Robin Holly is moderately drought tolerant. Water during extended dry periods to maintain vigor and berry production. Avoid waterlogged soil.
Soil & Fertilizer
Prefers moist, well-drained, acidic soil (pH 5.0–6.5). Sandy Florida soils may benefit from organic matter amendments. Apply a slow-release, acid-forming fertilizer in spring. A male Ilex × attenuata pollinator nearby is required for berry production.
