Detailed Botanical Description

Foliage & Growth Habit

Berberis thunb. ‘Red Compact’® features small, oval leaves arranged alternately along thorny stems. During spring, foliage emerges lime-green, transitioning to rich burgundy-red through summer and autumn. The plant forms a dense, rounded mound about 50 cm tall and wide, growing at a moderate rate of 5–10 cm per year. This tidy shape and modest dimensions make it perfect for small gardens, patio containers, and foundation plantings. Sharp, single thorns along stems offer added security in garden borders.

Flowers & Blooming

From April to May, the shrub is adorned with clusters of petite, fragrant yellow flowers. While subtle, their honey-like scent enhances the spring air. These blooms are highly butterfly-friendly, providing essential nectar sources. Flower clusters give way to decorative berries that persist into winter, offering a seasonal focal point.

Planting & Care Guide

Ideal Location

Plant Red Compact® in a site that receives at least six hours of sunlight daily. While it tolerates partial shade, full sun enhances its leaf coloration and flower production. Good air circulation helps prevent fungal issues, and gardeners should aim for a soil pH between 5.5 and 7.0 for optimal growth. Avoid low-lying areas where water may pool, as overly wet soil can lead to root rot.

Watering

Establish new plantings by watering deeply once or twice weekly, depending on rainfall, to encourage deep root development. After the first year, this barberry shows excellent drought tolerance but benefits from supplemental irrigation during extended dry periods. Avoid overhead watering to reduce the risk of leaf-spot diseases, and apply a 5 cm layer of organic mulch to conserve moisture and suppress weeds around the base.

Pruning & Maintenance

For best form, prune in late winter or early spring before bud break. Remove dead or damaged branches and trim any oversized shoots to maintain the compact habit. Rejuvenate older specimens by selectively cutting up to one-third of the oldest stems to ground level; new shoots will emerge vigorously. No heavy annual pruning is required, but light shaping after flowering keeps the plant tidy. Apply a balanced, slow-release fertilizer in early spring to support healthy growth.
