About Black cotoneaster
Cotoneaster niger, commonly known as black cotoneaster or black medlar, is a deciduous or semi-evergreen shrub belonging to the Rosaceae family. It is characterized by small white flowers in spring, followed by glossy black berries in autumn that persist on the plant. It's ideal for low hedges, borders, or as a standalone specimen in rock gardens and wild-style landscapes, offering seasonal interest.
Native range
Europe and temperate Asia
Care tips
It prefers full sun to partial shade for optimal flowering and fruiting. Once established, it is drought-tolerant but appreciates moderate watering during dry periods, avoiding waterlogging. It adapts to a wide range of soils, provided they are well-drained; a universal potting mix with some sand is suitable. A common mistake is excessive pruning, which can reduce flowering and fruiting, so light maintenance pruning to shape or remove dead branches is preferable.
