The genus Skimmia belongs to the Rutaceae family which is currently comprised of 4 species, all of which are evergreen shrubs which can tolerate drought and air pollution. Hailing from warm temperate regions of Asia, these delightful evergreens have clusters of leaves at the ends of shoots. Depending on the species, leaves are usually around 6-21 cm in length and 2-5 cm in width with a simple lanceolate shape and a smooth margin. Skimmia fruits are usually 6-12 mm in diameter and reddish to black in hue. Skimmia produce dense panicle clusters of flowers, with each flower around 6-15 mm in diameter featuring 4-7 petals per flower. Cultivars of S. japonica are the most common form of Skimmia used within the UK, the flowers and fruits make this evergreen a valuable source of food for birds and bees.
Skimmia are dioecious plants, meaning you get male and female flowers on different plants, as such it is important to plant female and male plants close together in order to ensure the female plants will bear fruit.
Skimmia are also easy to maintain due to minimal pruning requirements, they are slow growing and compact meaning only damaged and diseased material needs pruning around mid-spring time.
Moisture: Moist & well-drained
