CINERARIA WATERHOUSIANA.

plants are sufficiently strong they should be potted into 60-sized pots and placed in 
a cold frame, where they should stand all winter in no larger sized pot than a 48. 
In the spring (March) they should be shifted into 32 sized pots, and still kept in the 
frame ; in a month or six weeks they will begin flowering, when the lights of the 
frame should be tilted so as to admit an abundance of air : in order to have the 
plants dwarf, the head broad, and the flowers well expanded, they should stand as 
near the glass as possible ; when the flowers are open they should be taken into the 
greenhouse, where they will be quite ornamental. Any favourite variety that is 
desirable to keep more than one season, should be cut down after flowering and 
placed at the back of a greenhouse or pit, where they should have but little water. 
Sometime in August their roots should be divided and potted, treating them as re- 
commended for the seedlings above. For ornamenting the flower-garden the plants 
should be managed in this manner : seedlings sown in May should be preserved in 
small pots in a cold frame, and in the beginning of May following they should be 
planted out, where they will flower splendidly. C populifolia is excellent for this 
purpose, but the best way of treating it is to strike young plants in autumn, and 
keep them in small pots in a frame as directed for seedlings. As soon as the season 
admits, plant them out where they are intended to flower. Another method of get- 
ting good plants for the flower-garden is by taking the ofl'-shoots from the stools 
cut down in May, and potting them in small pots, and preserving them in a cold 
frame. The plants in vvinter should have plenty of air when the weather will 
admit, but no rain ; damp should also be kept under, which may in a great measure 
be done by judiciously admitting air. The following are the names of some of the 
hybrids raised and cultivated by Messrs. Henderson, Pine-apple Place, Edgeware 
Road, all of which are exceeding handsome and free flowerers : C. cruenta, var. 
Hendersonia^formosa^pulchella, elegans, and purpurea. The following are also 
highly worthy of cultivation either for the greenhouse or flower-garden: C. auran- 
tiaca, PetasiteSy lanata^ speciosa, hyhrida, geifolia, incana, prcecox, alba, and 
l(Bvigata. 
We earnestly solicit the attention of amateurs and gardeners in general to this 
exceedingly handsome genus of plants, which we are of opinion may yet be much 
more improved. Any one seeing Messrs. Henderson's plants, when in flower in the 
spring, would see much to stimulate them in the undertaking. We have seen there 
flowers very near black, and a good size ; others approaching to a blue, with broad 
and long petals : these by careful attention will come a good deal superior.
