Hybrid Mahonia

Berberis hortensis

The Story

Plant Bio

Berberis hortensis is a slow-growing broadleaf evergreen shrub of the tall Mahonia group, three to thirteen feet high. Long compound leaves of eleven to seventeen leaflet pairs give a bold architectural texture, spikes of bell-shaped yellow flowers open in late winter, and clusters of blue-black grape-like fruit follow.

Its value is the flowering season — bright yellow spikes in the depths of winter, when almost nothing else is out and early bees have nothing to work. The blue-black fruit is edible in moderation but causes stomach upset in quantity, so it is better left for birds. The leaflets end in sharp spines, so site it away from paths.

Uses & Benefits:

Ornamental UsesBold architectural evergreen foliage with bright yellow winter flower spikes and blue-black fruit.
Practical UsesEvergreen structure in shade, and the spined leaflets make it a useful deterrent barrier.
Ecological BenefitsFeeds bees at a time of year when almost nothing else flowers, and birds strip the fruit.

Planting

How to Grow

  1. Plant in partial shade in moist, freely drained soil.
  2. Site it away from paths; the leaflets are spined.
  3. Shelter it from cold drying winter wind.
  4. Water through the first two summers.
  5. Prune only lightly, after flowering.
  6. Leave the fruit for birds rather than eating it.

Pro Tip

It flowers in midwinter, so put it where you actually walk in January rather than in a summer border you never visit then.
