CHOICE PLANTS FOR ROCK GARDENS = 155 
LinARIA.—Among the members of this genus we have 
some of the daintiest little trailers for the stony areas 
of the rock garden or for tumbling over the face of a rough 
stone wall. L. hepaticefolia is one of the smallest of 
plants, scarcely attaining I inch in height. Its foliage 
is like a minute ivy leaf, its flowers are lilac, peeping out 
among the leaves like beads scattered over a velvet cushion. 
L. pilosa is another tiny plant with pilose or hoary stems. 
The leaves are green above and red underneath, and the 
flowers purple with a blotch of yellow at the nose, the 
blossoms of all the Linarias being shaped like miniature 
antirrhinums. L. repens, ‘‘ Snowflake,” is of semi-pros- 
trate habit and rambling growth. The much branched 
stems are wiry, well furnished with narrow, pointed, pale- 
green leaves, and at the ends of the branches and side 
stems appear innumerable tiny flowers of pure white. 
The plant continues to bloom for months, and presents 
a delightfully light and airy appearance. Even as a cut 
flower for intermixing with larger blooms of bright colours 
the Snowflake Linaria is exceptionally useful, and alto- 
gether it is a plant to seek and cherish. 
Other desirable Linarias are origanifolia, with slender 
spikes of violet orange-throated flowers; pallida, with 
individual flowers of purple, which are large by comparison 
with the total size of the plant; L. alpina, and its varieties 
rosea, pallida, alba, and reticulata, all of which make 
twiggy green stems clothed with narrow glaucous green 
foliage ; and the familiar ivy-leaved toad flax, L. cymbalaria, 
which grows in the chinks of old walls and even drapes 
hard-faced flints with refreshing greenery. This plant
