Senna Alata, also known as Cassia Alata, candle bush, candle stick, candle tree or Christmas candle plant is an evergreen shrub that can grow up to 3.5 m high. The shrub is widely distributed in tropical countries. It is native to South America, but has been planted widely for medicinal and ornamental flowering purposes. Senna Alata has bright yellow flowers that are similar to a yellow candle and that attract butterflies and bees. When in buds, the flowers are concealed within swollen orange bracts. They are 2.5-5 cm wide. At maturity, the 25 cm long fruit splits open along one side with the flattened, kite-shaped seeds hanging out on a short stalk. The leaves are up 75 cm long and they close in the dark. Senna Alata performs best in full sun but in zones 7,8 and 9, it is possible to grow it as an annual. Senna alata plants are drought-tolerant, but they will still benefit from being watered regularly and given a layer of mulch during the hottest summer months. Hardiness Zone: 10-11
