The name C. aethiopica has sometimes been misapplied to this species; true C. aethiopica (L.) N.E. Br. has a one-sided spike of up to 15 flowers, and is rare in cultivation.Yellow flowered plants have been known as var. duckittii L. Bolus or as the cultivar 'Lutea'; their colour is apparently due to one recessive gene.
C. bicolor (Ten.) N.E. Br. with 2-toned yellow and red flowers is occasionally available; it produces prolific seed and has weed potential.
