Summary

Chasmanthe aethiopica, commonly known as Cobra Lily, is a deciduous perennial bulb native to the fynbos and grasslands of South Africa, particularly in the Western Cape. It typically grows to a height of 2 feet (0.6 meters) and can spread 1-4 feet (0.3-1.2 meters) wide. The plant features sword-shaped leaves and produces striking, tubular orange to red flowers on tall spikes during late winter to early spring, which are particularly showy and attract pollinators such as sunbirds.

Cobra Lily is valued for its vibrant, exotic-looking flowers and is often used in borders, as a focal point in gardens, or naturalized in grassy areas. It is relatively low maintenance, requiring minimal water once established, making it suitable for water-wise gardens. It thrives in well-drained soils and can tolerate a range of soil types, from sandy to loamy. While it prefers full sun to part shade, in hotter climates, some afternoon shade can be beneficial. After flowering, the foliage dies back, and the plant remains dormant until the next growing season. It is not known for serious pest or disease problems, but it can be sensitive to overly wet conditions which may cause bulb rot.CC BY-SA 4.0
