Berry Heavy® Gold Winterberry Holly (Ilex verticillata 'Roberta Case') brightens winter landscapes with abundant clusters of large, golden berries that persist well into the cold months. Standing six to eight feet tall with glossy green leaves, this shrub creates an impressive focal point or colorful hedge, drawing attention when most plants lie dormant. With unique golden berries rather than traditional reds, Berry Heavy® Gold offers an elegant alternative for gardens, mass plantings, or stunning seasonal cuttings. It thrives in wet and boggy conditions, offering superior versatility over other hollies.
Choosing live holiday décor like Berry Heavy® Gold provides lasting value beyond festive celebrations. This living holly makes a thoughtful gift, offering recipients something beautiful and meaningful to plant in spring. Indoors, the golden berries serve as striking natural ornaments, adding warmth to winter interiors. Later, you can move the shrub outdoors to provide shelter and nourishment for songbirds.
Holiday Berry Heavy® Gold Winterberry Holly Care
Keep Berry Heavy® Gold in a cool spot indoors where it receives indirect but bright sunlight and maintain consistently moist soil without allowing waterlogging. Avoid placing it near direct heat sources, as cooler conditions help the berries remain fresh and attractive. Minimal pruning indoors ensures optimal berry production when the plant transitions outdoors.
When the risk of frost passes, gradually introduce your holly outdoors, increasing its exposure each day. Select a planting site offering full sun to partial shade with moist, slightly acidic soil. Dig a planting hole wide enough to comfortably fit the root ball, position the shrub with its crown level to the soil surface, backfill, and water thoroughly. Ensure proper berry production by planting a compatible male pollinator like Mr. Poppins® Winterberry within approximately fifty feet.
