ingredient in the manufacture of Persian Insect-powder. (Dalmatian 
Insect-powder is furnished by a closely-allied species, viz. P. cinerarie- 
folium.) Under cultivation it has run into a very large number of 
forms varying in size and colour, and dignified with florists’ names. A 
few of these are shown in Plate 151.

P. rosewm is one of the most useful plants for 
the gardener, owing to the highly ornamental character 
of its flowers and foliage, its adaptability alike for beds, borders, vases, 
pots, or for cutting purposes. It likes a rich deep soil, well manured, and 
must have plenty of water in dry weather; this is an important item in 
its treatment, for if neglected the flowering period will be a short one, 
whilst given liberal waterings the plants will continue to bloom right on 
through summer and autumn. Propagation is chiefly effected by division 
of the roots. The instructions for cultivation given under the head of 
Chrysanthemum apply generally to these plants, except that allowance 
must be made for their more herbaceous character.
