About this plant
This is an interesting holly, with heavily prickled leaves. Prickles cover the upper surface of the leaves in a curious manner. The leaves are very striking mid-green with broad creamy edges. It is a very slow growing variety. This plant is male, so there are no berries. Plantsman Roy Lancaster recommends this as an intriguing gift for young gardeners.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Hedges · Planting
Suitable for creating a prickly hedge
This plant has thorns, so makes a good defensive barrier. Weeding around plants with prickly foliage can be painful without suitable gloves and clothing for protection.
Hedges · Planting
Close clip for a formal hedge
The hedge is most attractive when close-clipped if a formal hedge is required.
Hedges · Planting
Hazardous to animals
Don't plant this hedge on a boundary, or any position where it could be eaten by animals grazing in meadows, or otherwise left its vicinity. Some parts of the plant are poisonous.
