The plant, like all the species of the genus, requires pro- 
tection in winter: but during summer it will succeed in the 
open air. Under such circumstances, however, the flowers 
seldom open in their native brilliancy. The best way of cul- 
tivating them is in a frame, made upon the principle of Mr. 
Ward’s cases, described by Mr. Ellis in the Gardener’s Ma- 
gazine for September 1839, and only ventilated occasionally. 
In such a frame I saw them in wonderful beauty in the Kew 
Garden in the autumn of 1838. 
The seed may be sown in any season, except late in 
autumn or in winter; for when the plants are weak at that 
time they are almost sure to perish from the want of light. 
The soil used in potting should be loam and peat mixed with 
a little sand. The plants should be placed near the glass, and 
after they are strong enough be fully exposed to light and air.
