Barberry ‘Royal Cloak’

Barberry ‘Royal Cloak’ (Berberis thunbergii ‘Royal Cloak’). Berberis thunbergii 'Royal Cloak', or Japanese Barberry 'Royal Cloak', is a vigorous and very colourful ornamental shrub, appreciated for its dark purple foliage with purplish-red reflections, which maintains a remarkable intensity throughout the season. Its full and well-structured bushy habit allows it to play a strong role in decorative hedges, contrasted beds, or background plantings. In spring, small pale yellow flowers appear discreetly, followed by decorative red berries that extend visual interest into autumn.

To plant Barberry ‘Royal Cloak’, choose a suitable exposure: full sun to partial shade. The recommended soil is well-drained and tolerant. Water the root ball before planting and ensure water can drain after planting. During establishment, check moisture by hand before watering again. Spread mulch around the base, leaving the collar clear. Avoid systematic fertilizer applications without considering soil richness. In Quebec, choose a period when the soil is thawed and easy to work with. In hot weather, monitor recently planted plants more frequently.

Allow a width of 1.5 m (5 ft) to arrange this plant's space in the garden. The indicated height of 1.8 m (6 ft) helps choose its position relative to neighbouring plants. Keep access to the base to weed, check moisture, and remove damaged parts. Associate this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
