Metalasia muricata, commonly known as white bristle bush or blombos, is a hardy virgate or twiggy shrub with honey-scented flowers usually 2–4 m tall, woody with a rounded crown, and an important component of the coastal and mountain fynbos regions of Southern Africa. It is encountered in a number of forms in its extended distribution, some of which are tolerant of frost, wind and poor sandy soils. A member of the Asteraceae or daisy family, Metalasia has some 54 species in South Africa, many of them found in the Western Cape. The name of the genus Metalasia is derived from 'meta' which can have many meanings, but in this case is intended as 'reverse', and 'lasios' meaning 'woolly', an allusion to the woolly reverse sides of the leaves; 'muricata' means warty with short, sharp points like the shell of the Murex. Metalasia is also found in KwaZulu-Natal, Free State, Eastern Cape and Lesotho. The leaves of Metalasia muricata are some 6 mm long, in tufts or fascicled, closely packed about the stem, acicular or needle-like, sharp-tipped, greenish-grey and may be either glabrous or woolly. Flowers range from white to pink or purple, are bisexual, and produce fruits or cypselae which in this genus are ribbed nutlets with bristly pappi. The greyish bark is slightly striated. This is one of the first plant species to reappear after a fire, and offers shelter to less resilient plants when they emerge after being burnt. It is occasionally used with Marram grass and Chrysanthemoides monilifera to stabilise coastal dunes.
White bristle bush exhibits strong resistance to diseases and is generally not susceptible to them. In terms of care, the plant is fairly low-maintenance. When grown outdoors it needs only minimal watering, and larger specimens typically do not require pruning. Smaller plants, however, should be pruned after they have finished blooming. The white bristle bush is suitable for anyone with an outdoor area, such as a garden or a deck, and does not demand a great deal of care experience.
How to keep Metalasia Muricata.
Light
The white bristle bush comes from open habitats, such as sunny meadows and forest edges, where light is plentiful. It does best in full sun but can also tolerate partial sun, adapting well to different sunlight conditions.
Water
The white bristle bush, native to the fynbos region, flourishes in Mediterranean climates characterized by wet winters and dry summers. It favors well-drained soils and is drought-resistant, though it benefits from being watered weekly. Being an evergreen, it retains moisture throughout the year, making it a great choice for ornamental use both indoors and outdoors.
Temperature
White bristle bush is native to a climate with temperatures ranging from 59 to 100.4 °F (15 to 38 ℃). Preferring warmer conditions, it thrives in moderate to high temperatures. In cooler seasons, consider providing extra heat and protection.
Fertilizer
The timing of fertilizing the White bristle bush is important. Start fertilizing in early spring and continue once a month until early summer. Fertilizer encourages lovely blooms and supplies energy both during dormancy and throughout active growth.
Pruning
The white bristle bush is known for its dense, rounded shape and distinctive white bristle-like flowers. To encourage new growth and more abundant flowering, it’s best to prune in early spring. Recommended pruning techniques include removing dead branches and shaping the plant to maintain its compact form. Regular pruning not only enhances the density of the foliage but also improves air circulation, reduces the risk of disease, and allows better light penetration.
