This plant is cultivated for its yellow trumpet-shaped flowers, appearing in winter and spring. Each flower has a pale green calyx with a long spur. As it does not tolerate freezing temperatures, it can only be grown outdoors in the mildest parts of the UK. Otherwise it must be grown under glass. It has gained the Royal Horticultural Society's Award of Garden Merit.^[2][3]
