tlie bright golden border surrounding the rich velvety 
red or crimson zone outside the centre or eye of the 
flower. The “Fancy” or “Giant” Polyanthuses 
have large blossoms varying from pure white and 
yellow to deep purple and crimson. Besides the 
single-flowered varieties there are many double- 
flowered ones, and also “ Hose-in-Hose ” forms, in 
which the calyx is an exact counterpart of the corolla. 
Although Polyanthuses grow well in any good garden 
soil, they like a rich, sandy loam, and partially shaded 
spots. The best time to divide the plants is when the 
leaves have begun to turn yellow. They should be 
transplanted before the end of September so as to 
become well-established before winter sets in. 
Single and double varieties are shown on Plates 
5 and 6. 
POLYGONATUM multiflorum ( Solomon’s Seal ). — 
This general favourite has arching stems and droop- 
ing clusters of white or greenish -white flowers in May 
and June. It flourishes in ordinary good garden soil 
in partially shaded places and may be increased by 
division of the thick creeping rootstocks in autumn 
when the leaves are withering away. 
POLYGONUM ( Knotweed ). — These free growing 
and ornamental plants sometimes spread over a garden 
with great rapidity. Most of them flourish in any 
garden soil, and are effective in foliage and blossom 
when in bold groups. Some of the kinds are suitable 
for the flower border or the rock garden, and among 
these the best are : — P. affine, 6 to 9 inches high, 
with oblong lance-shaped leaves and dense spikes of 
rosy red flowers from August to October. P. Bistorta
