THE FLOWER GARDEN. 
soil in a cold frame in autumn or spring. Seedlings do not 
flower for several years. Also by cuttings of the fleshy roots 
in March. The plants emit a strong resinous odour which is 
capable of ignition at night; hence its name, Burning Bush. 
Digitalis (Foxglove). — The Common Foxglove (D. pur- 
purea) is a well-known wild plant. It belongs to the Nat. Ord. 
Scrophulariacem, and is a biennial. The common kind is only 
grown in wild gardens and woodland borders as a rule. There 
are, however, some very pretty strains which deserve a place 
in the mixed shrubbery or ordinary borders. For instance, 
alba is a pretty, white variety ; campanulata, a dwarf variety, 
growing i8in. high, and bearing a large bloom at the summit 
of the spike ; gigantea, a giant strain with large flowers ; 
gloxinioides, with gloxinia-like flowers, which are prettily 
spotted. Of the latter there are three special kinds : alba, 
white, spotted with purple ; rosea, rose, spotted with purple ; 
purpurea, purple spotted. The colours of a good mixed strain 
range through every shade of cream, rose, white, red, and 
purple. Seed may be sown outdoors in spring, the seedlings 
transplanted 6in. apart as soon as large enough to handle, and 
finally planted out in September in their flowering quarters. 
The seedlings flower the second year after being raised from 
seed. In the shrubbery or wild garden the seed may be 
scattered over the surface and raked in. Once the plants get 
established seedlings from self-sown seed will be plentiful, and 
these can be transplanted in showery weather. Foxgloves do 
well in shady, partially shady, or sunny positions. They show 
to best advantage when grouped or massed together. The 
only perennial species worthy of note is D. ambigua (Syn. D. 
grandiflora). This 'grows 2 to 3ft. high, and bears yellow 
flowers in summer. This will succeed in ordinary soil in sun 
or shade. Increased by seeds. 
Dlmorphotheca (Cape Marigold). — Hardy annuals, 
natives of the Cape, and members of the Daisy family (Com- 
positae). Pretty and showy plants to grow on a sunny border. 
D. pluvialis has white marigold-like flowers with a purplish- 
violet exterior, and grows i8in. to 2ft. high. A variety of 
the latter named Pongei has double or semi-double flowers. 
Easily reared from seeds sown in ‘patches or masses where the 
plants are required to grow. Sow in March or April. Thin 
out the seedlings early to six or more inches apart. 
Dipsacus (Teasel). — The Teasels are hardy biennials, 
with bold, prickly foliage and conical flower-heads. They 
belong to the Scabious order (Dipsaeeae), and are of too coarse
