An easy-to-grow fragrant evergreen shrub

Sarcococca, is a compact evergreen shrub that is native to Southeast Asia and the Himalayas. It is commonly known as ‘sweet box’ due to its vanilla fragrance, and generally grows up to a height around 1.5m. It is closely related to common box, Buxus sempervirens, but has sweeter smelling winter flowers. It adds an appeal to any garden with its heady fragrance and versatility. 

Sarcococca thrives in shady areas, such as beneath trees or in woodland gardens. It compliments other winter flowering woodland plants, such as hellebores, crocus and snowdrops. It can also be grown as an informal, lightly clipped hedge along paths and entryways – ideal for adding evergreen structure as well as an appealing scent. They are low maintenance plants, so pruning is rarely required. Furthermore, these adaptable shrubs are tolerant of dry shade and even atmospheric pollution, making them a hardy addition to your outdoor space.

How to grow and care for Sarcococca

Sarcococca is an adaptable shrub that can be planted at any time of year; however, they will achieve the best results when planted in spring or autumn. These shrubs prefer moist, but well-drained, organic-rich soil, but once established, they can tolerate dry shade as well. As a result, they are ideal for planting under trees or in shady areas. Sarcococca can grow in partial or full shade, and they do not require much sunlight to thrive.

Sarcococca is a low-maintenance shrub that requires minimal pruning as they are low-growing shrubs, compact, and well-branched. Watering your sarcococca thoroughly is vital in the first few seasons after planting, particularly during dry periods. It’s important to keep the soil consistently moist without overwatering. As the plant grows and establishes itself, its water requirements decrease significantly, and requires only minimal maintenance. Pruning in spring, after its flowering season, can help maintain their size and shape if they outgrow their designated space. Mulching the plant in spring with organic matter, helps to conserve moisture and suppress weeds. Additionally, removing any dead or damaged branches keeps it looking its best. Avoid cutting into old wood as this can reduce flowering the following year.

Pests & diseases that affect this genus

Sarcococca is generally considered to be a tough and disease-resistant plant, rarely affected by pests and resistant to deer and rabbits.

Aphids can gather on the leaves and stems, causing minor damage. However, Sarcococca is usually able to tolerate and recover from these infestations without significant harm. If aphid populations become a problem, then regular monitoring, and appropriate practices, such as using water sprays, can help keep them in check.

Another pest that can affect Sarcococca are scale insects. These tiny insects feed on the plant’s sap and can weaken the plant over time. This is easy to treat, though. Cutting off and disposing of the affected leaves will prevent scale insects from spreading.

Spider mites are another common pest to monitor. While feeding on the foliage, these pests spin webs around the shrub’s branches and leaves. They can cause yellowish spots to appear on the plant’s leaves. To combat these pests, you must first prevent them from reproducing. One method is to mist the affected plants with tepid water or use an organic pest control option such as insecticidal soap.
