MARSH MARIGOLD.

there are many distinct races or groups of China Aster 
with many shades of colour. They can all be raised 
easily from seed sown thinly in spring in a light 
sandy soil. The seedlings are “ pricked out ” and 
“hardened off,” and by the end of May are fit for the 
open air. They may be used in bold masses or groups, 
or in beds by themselves, and so long as the soil is 
fairly rich and well drained, they will grow with great 
freedom and flower profusely. 
CALTHA palustris ( Marsh Marigold ). — The common 
Marsh Marigold, or King Cup, flourishes in marshy 
spots near the banks of ponds, streams, and rivers. 
It has large glossy green roundish kidney-shaped 
leaves, and the large golden-yellow blossoms from 
March to June. The double-flowered variety (Plate 11, 
fig. 29) looks very fine, and with the single type may be 
easily grown in moist garden soil, or on the banks of 
lakes, ponds, &c. Once established they maybe allowed 
to look after themselves ; otherwise the easiest way to 
increase the plants is by dividing the rootstocks. 
Other Marsh Marigolds worth a place are biflora and 
leptosepala, both with white flowers. 
CALYSTEGIA ( Bearbind ). — These charming 
climbers are usually ranked as weeds, and indeed 
become so when not kept to their legitimate use 
of covering old hedges, arbours, trellises, &c. They 
flourish in any garden soil, and rapidly increase by 
means of the creeping roots. The common British 
Bearbind (C. Sepium ) is a lovely plant with broadly 
hastate leaves and large white or pinkish bell-shaped 
flowers during the summer and autumn months. A 
double-flowered form of a Chinese species (C. pubes-
