Brachylaena transvaalensis, also known as the Forest silver-oak, is a medium to large tree native to the eastern escarpment of South Africa. Growing to a height of 10 – 25 m, this tree is predominantly evergreen but may occasionally be deciduous depending on its environment. The main stem is typically single and straight, with bark that is initially smooth and grey to light brown in color. As the tree matures, the bark develops vertical striations, adding to its character.

The attractive foliage of the Brachylaena transvaalensis makes it an eye-catching addition to gardens. Its leaves are narrow and elliptic, with a glossy dark-green upper surface and silvery white underside, creating a striking contrast. Pale white, fragrant flowers bloom from July to December, appearing in dense clusters at the tips of branches. These flowers later give way to small dry fruits, which are crowned with tufts of cream-colored bristles, and can be seen from September to November.

The Forest silver oak is well-known for its hardiness and fast growth rate, thriving in a variety of conditions. Its non-invasive root system makes it ideal for medium-sized gardens, where it won’t damage surrounding structures. Frost-hardy and water-wise, the Forest silver-oak is a great choice for sustainable landscaping. The tree also attracts a variety of insects and birds, contributing to local biodiversity. Additionally, its dense foliage provides natural screening, making it an excellent choice for privacy protection in gardens and outdoor spaces.
