There are 4 species of Skimmia and all are found in Asia; all of the species having attractive berries, aromatic foliage and fragrant flowers.
The Skimmia species is a member of the Rutaceae family which we know better for giving us citrus fruit such as oranges, lemons, limes and Grapefruit. Other members are as diverse as the bitter herb Rue(Ruta) and Zanthozylum which gives us Sichuan Pepper and Prickly Ash. Many members of the family are edible and provide us with important fruit, spices and medicinal components. Skimmia is probably is the most important of the strictly ornamental plants, even the birds don't seem to eat the berries.
Skimmia japonica and all its forms are easy plants to grow, I do absolutely nothing with mine, except chop it back to clear the path. Ideally they like fertile rich soil which is slightly acidic but tolerate clay soils quite well, we live in a chalky area and the plant still seems to thrive. They like a site which is well-drained but is well watered during the hot summers as they do not like drought conditions but again mine thrives in a sun scorched south facing garden. They prefer a site which is dappled or is more on the shady side or their leaves will yellow even in a strong winter sun. Mine being in an open sunny site suffers a little from yellowing but I quite like having the mixture of dark glossy green with the brighter yellow sun scorched leaves. As they are evergreen they will do best being in a location which is protected from drying winds especially in the winter season. It also looks stunning with a heavy winter frost.
Use Skimmia japonica as an accent, in a winter garden, for fragrance in the spring, along paths where you brush the aromatic foliage. Their colourful berries are bright winter interest and the foliage is not popular with pests. They work well as foundation plants especially when placed near entrances or windows. Skimmias are also popular in a woodland setting or in borders as they are very low maintenance and will need little care over their long life.
