108 FAMILIAR GARDEN FLOWERS. 
feet high, and produces rather small clusters of bluish- 
purple flowers early in the summer. It is a bog plant, and 
when planted in the garden, therefore, a damp situation 
will suit it best. 
The large-flowered pea (LZ. grandiflorus) is a fine plant, 
with hairy herbage and large rosy flowers, produced in 
clusters of two or three. It runs about four feet, and 
requires a warm sandy or light loamy soil. It is a capital 
plant for the front of a rockery. 
The Californian pea (LZ. Californieuvs) runs about four 
feet; the flowers are light purple and white, extremely 
pleasing. This also is a good rockery plant, being allowed 
to fall over and make festoons in its own way. 
The tuberous pea (/. tuberosa) is of low growth, rarely 
running more than three feet, and generally less. The 
flowers appear early, and are of a pleasing rose colour. It 
is a good rock and border plant. The tuberous root is 
edible, and has been sometimes spoken of as a likely substi- 
tute for the potato. But there is no substitute for the 
potato, unless it be bread—which is like saying the best 
substitute for silver is gold.
