BEAUTIFUL GARDEN FLOWERS. 
cens fl. pi.), lias somewhat similar foliage, but the 
large double blossoms are composed of long wavy, 
and reflexed petals, varying in colour from pale to 
deep rose. C. Soldanella is a native of our sandy 
shores. It has trailing stems, roundish kidney-shaped 
leaves, and pale purple or pink blooms. It is a good 
plant for trailing over stones, in the rock garden, in 
sandy soil. There are a few other species not so well 
known, the best perhaps being dahurica from the 
Caucasus, having oblong heart-shaped leaves and rosy 
purple flowers. (See also Convolvulus, and Ipomsea.)

posed of annuals, biennials, and perennials, differing 
greatly in size, habit, and blossom, but all possessing 
a certain gracefulness and charm. 
Annuals. — Most of the annual kinds like drabse- 
folia, Erinus, have blue blossoms, but macrostyla 
( remarkable for its large club-like style in the centre 
of the flower) has purple blossoms conspicuously 
veined with violet ; while the flowers of punctata are 
white spotted with red within. These and many other 
annual Bell-flowers are easily raised from seed sown 
in gentle heat in spring (see p. 9). 
Biennials. — Of the biennial kinds there are 
many species — mostly with blue or purple flowers — 
but none of them compares with the well-known 
Canterbury Bell (C. Medium) and its varieties. The 
blossoms of a few forms are shown on Plate 19, and a 
white one is also depicted on Plate 25. There are many 
still finer forms in cultivation, having broad bell-shaped 
corollas with white, blue, purple, rose, pink and inter- 
mediate shades of colour. One very remarkable
