HELIANTHEMUM. Holly Rose. H. Tuberaria (of 
B. M.) is a synonym of H. globularixfolium. These ever- 
green shrubs are extremely valuable as being amongst 
the comparatively few subjects which will flower pro- 
fusely upon dry, hot, sandy soils. The brilliant flowers 
open in bright sunshine, and are of good size, but of no 
use for cutting. They are short-lived upon the plant, but 
atone for this by their abundance and 
j=) oe] ~4the time over which the flowering period 
extends. They are not rampant growers, 
and may be readily kept within bounds 
by slight prunings in spring. Besides the 
species referred to in Vol. II., there are 
several most desirable garden forms, both 
single and donble, the best of the former 
including Bronze Queen, Pink Beanty, 
Salmon Qneen, Snowflake, and Sulphur 
Gem; and of the latter, Mrs. C. W. 
Karle. 
HELIANTHUS. The perennial 
Helianthus (Fig. 441) are extremely usefal 
plants, and may be effectively employed 
in beds, borders, or shrubberies. They 
are very robust, and may therefore be 
left to take care of themselves. Like 
the members of the genus generally, they 
are sun-loyers, and a sunny position in a 
well-drained, rich border is where they 
are seen to perfection. Periodically it is 
advisable to lift them and give the roots 
entirely fresh quarters, as, being some- 
what gross feeders, they quickly take 
the nutriment ont of the soil. When 
propagated by divisions, these may be 
made in either spring or autumn. 
Of recent years some very fine garden 
varieties have been obtained, in some 
cases later as to flower than the species, 
and with the blossoms well above the 
foliage. The best kinds are Bouquet d’Or, 
H. G. Moon, Meteor, Miss Mellish, Qneen 
Victoria, and Soleil @’Or. For fuller 
information on the perennial Sunflowers 
the reader is referred to a paper by 
Mr. D. Dewar, in the “Journal of the 
Royal Horticultural Society,’’ vol. xv., 
part i., p. 26.
