Wildlife Food & Habitat
WildlifeThe persistent red berries are an important winter food source for birds including American robins, cedar waxwings, and mockingbirds. The dense, evergreen canopy provides excellent shelter and nesting habitat for wildlife. [source]
Traditional Beverage & Remedy

Harvest Tips
Cut branches for holiday arrangements in November through December after berries have fully colored and hardened. Use sharp pruning shears and cut at a 45-degree angle above a leaf node. Branches last 3-4 weeks in water with fresh cut and preservative added. Harvest sparingly (no more than 1/3 of canopy) to maintain plant structure and wildlife food sources.
Fun Facts
- 🌱 Nellie R. Stevens is a female clone of Ilex × attenuata developed in Louisiana, and produces exceptional quantities of berries even without a male pollinator nearby, though berry set is improved with a compatible male holly present.
- 🌱 Holly berries are not actually berries botanically—they are drupes (stone fruits) containing 2-4 hard seeds, which is why birds must work to consume them and why the seeds are widely dispersed.
- 🌱 Ilex plants have been associated with winter solstice celebrations for over 2,000 years across European, Celtic, and Christian traditions, making them one of humanity's oldest symbolic plants.
