A genus of South African Amaryllids, still well known as Imantophyllums. They have strong deep-green strap-shaped leaves, and throw up large heads of showy bell-shaped or tubular flowers somewhat like those of the Vallota or Scarborough Lily. They are easily grown in a compost of rich fibrous loam, leaf mould or well - rotted manure, and sand, in about equal proportions, and require warm greenhouse treatment, or, say, a minimum winter temperature of 50° to 60° F. Propagation by dividing the tufts usually takes place in February or March, but stock may be more readily raised from seeds. These should be sown when thoroughly ripe in a temperature of about 70° F., the seedlings being in due course pricked out and grown on in small pots. It takes about three years to attain the flowering stage. The best-known kinds are: C. cyrtanthiflora, beautiful salmon red; C. Gardeni, orange and red; C. miniata, scarlet with a yellow throat; there are, however, many varieties of this species, including a pale creamy-yellow one called citrina. C. nobilis, bright red and yellow.
