Although some of the species of Hamanthus are 
frequently described as cool greenhouse bulbs, and some 
even recommend cultivating them in warm borders in the 
open air, yet they succeed best in a temperature of from 
50deg. to 60deg. during the growing season. ‘The sorts 
with well-developed bulbs should have these quite buried 
in the soil. When in flower, the blossoms will last 
n cooler quarters. Propagation is effected by offsets,
