Ilex × 'Nellie R. Stevens'
nellie R. stevens holly
Garden hybrid — {Ilex aquifolium} (English holly) × {I. cornuta} (Chinese holly); originated in Mississippi
Overview
Ilex spp. × 'Nellie R. Stevens' is a hybrid holly, growing 180–360 inches (450–900 cm) tall and 120–180 inches (300–450 cm) wide. Dark green glossy spiny evergreen foliage with abundant red berries in fall and winter. A hybrid of I. aquifolium × I. cornuta. Named after Nellie R. Stevens of Mississippi, who discovered the original seedling. The cultivar produces berries with minimal or no pollination (parthenocarpic tendency) — most hollies are dioecious and require a nearby male pollinator for berry production on female plants. A nearby male holly increases berry set but is not strictly required. Fast-growing for a holly at 12–24 inches (30–60 cm) per year. Deer-resistant (the spiny leaves deter browsing). The red berries are toxic to humans (gastrointestinal irritation: nausea, vomiting) but are consumed safely by birds, which are the primary seed dispersal agents. Zones 6–9. Full sun to partial shade. Tolerates a range of soil types. Scale insects and holly leaf miner are the primary pests. The spiny leaves can scratch skin during pruning; gloves and long sleeves help reduce exposure. Responds well to hedging and formal shearing.
