winter. G. argenteum is one of the silvery leaved kind, 
and G. cinereum another. G. grandiflorum is a_blue- 
flowered plant of much beauty, and G. Endressi is a very 
fine rosy pink with dark veins. G. sanguineum, a bright 
red species, has also both pink and white forms, all of 
them being charming plants capable of making a delight- 
ful display throughout summer and autumn. Two double- 
flowered varieties, G. pratense flore plena and pratense 
alba plena, purple and white respectively, are of upright, 
fairly tall growth, and their flowers, borne on stiff, straight 
stalks, are both showy and more durable than the singles. 
In all, there are close upon three dozen species and varieties 
of the genus, those named being a few that may be planted 
with confidence in any rockery or alpine bed. Propaga- 
tion by division is a simple matter, and the plants increase 
in size very rapidly. 
GruM.—This is another family of very easily grown 
plants, possessed of elegance of form and brightness of 
colouring, and having the additional good quality of 
being very prolific and continuous in regard to flowering 
capabilities. The Geums have effective, fresh-looking and

is attractive throughout the year. The majority of the 
species produce their flowers on fairly long, practically 
erect, and generally branching stems, and are light and 
graceful, either in the garden or in a cut state. 
There are vivid scarlets, rich orange, bright yellow, and 
reds of various shades, some double flowered, but the larger 
number singles, simulating in form and appearance the 
blossoms of the strawberry. The best positions on the
