Carmine-red leaves with a fine golden edge make Berberis thunbergii Ruby Star a compact color feature for the front of a border or a patio container. The slow-growing, rounded shrub reaches about 10 to 20 inches high and 10 to 20 inches wide, so it fits small gardens and edging.
Small yellow flowers appear in May and June, followed by red berries in early fall. Grow it in full sun for the most vivid foliage, though partial shade is tolerated. Plant in moist, well-drained soil and avoid waterlogged ground. The thorny stems can scratch skin, and the ornamental fruit should not be eaten; wear gloves when handling the shrub.
