The Story
Plant Bio
Ilex x meserveae, or Meserve hollies, are hybrids known for their excellent cold hardiness, glossy blue-green foliage, and classic spiny holly leaves. They are dioecious, requiring male and female plants for berry production. 'Blue Girl' is a popular female cultivar prized for its dense, branching habit, lustrous dark blue-green foliage, and profuse production of large, bright red berries that persist through winter. It needs a male pollinator like 'Blue Prince' to set fruit.

Planting
How to Grow
- Select a site with moist, well-drained, acidic soil in sun or part shade.
- Dig a hole twice as wide as the root ball.
- Set the plant in the hole, with the root flare at soil level.
- Remember to plant a male pollinator nearby for berry production.
- Backfill with soil, water thoroughly to settle.
- Apply a 2-3 inch layer of mulch around the base.
Pro Tip
For maximum berry production, plant one 'Blue Prince' for every 3-5 'Blue Girl' hollies, ensuring they are within 50 feet of each other.

Care Guide
Do

Don't
