Protea effusa, commonly known as Scarlet Sugarbush, is an evergreen shrub native to the fynbos biome of the Cape Provinces of South Africa, particularly in mountainous areas. This plant typically reaches a height and width of 3-5 feet. It boasts a striking display of cream, yellow, orange, and red flowers during the fall and winter months, which are highly valued for their ornamental qualities. The flowers are showy and make an excellent addition to the winter garden when few other plants are in bloom.

Scarlet Sugarbush is appreciated for its unique and vibrant flowers, which can also be used as cut flowers due to their long vase life. It is often cultivated in rock gardens, as a specimen plant, or in botanical collections that focus on South African flora. While it can be challenging to grow, understanding the specific climate and soil conditions from its native habitat is key to successful cultivation. It requires full sun exposure and well-drained, acidic soil. Overwatering should be avoided, as it is adapted to low or medium water conditions. Protea effusa is not known for significant disease problems, but it can be sensitive to root rot if drainage is poor. It is also not tolerant of heavy frost and requires protection in colder climates.CC BY-SA 4.0
