CALLISTEPHUS. 



top of the steins. Its foliage resembles 

 that of one of the Mimulus, creeping along 

 the ground, and it is a very interesting 

 dwarf rock-garden plant. 



C. Pavonii is a noble species, the 

 largest in cultivation. It is from 2 to 4 

 ft. high, has large light-green, much- 

 wrinkled foliage, from June to September 

 bearing large, pale-yellow, slipper-shaped 

 blossoms. It is a fine object against a 

 warm south wall, but at the approach of 

 winter it should either be lifted or pro- 

 tected. Peru. 



C. violacea is a pretty species, with 

 small helmet-shaped flowers, which are 

 rich purple and spotted ; succeeds well on 

 warm borders or the rock-garden, and, if 

 slightly protected, withstands mild winters 

 in the south. Chili. 



Calendula officinalis (Pot Marigold}. 

 An interesting old hardy biennial ; one of 

 the best for autumn and winter flowering 

 in almost every garden ; the petals were 

 formerly used to flavour dishes in old 

 English cookery, hence its name. A 

 variety of kinds is now offered by the 

 seed houses. The plants are among the 

 best biennials for autumn and even winter 

 flowering. For late blooming, seed should 

 be sown in July. The plants usually sow 

 themselves freely, and may be sown in the 

 open ground either in spring or autumn. 

 The pretty variety called meteor and other 

 forms are improvements on the old showy 

 form. 



CALLA (Bog Arum}. C.palustris is a 

 small hardy trailing Arum, which has pretty 

 little white spathes. Though often grown 

 in water, in a bog or muddy place it will 

 grow larger. For moist spongy spots near 

 the rock-garden, or by the side of a rill, 

 it is one of the best plants, but its beauty 

 is best seen when it is allowed to ramble 

 over rich muddy soil. N. America and N. 

 Europe. Flowering in summer, and in- 

 creasing rapidly by its running stems.

CALLIRHOE (Poppy Maiiow\& 



small and handsome genus of North 

 American plants, of the Mallow order, of 

 which some half-dozen kinds are known 

 in our gardens. They are hardy herba- 

 ceous perennials, and succeed well in the 

 open border in rich light soil. 



C. alcseoides is an erect herbaceous 

 perennial, with the habit and general ap- 

 pearance of Malva moschata, the flowers 

 from i inch to \\ inches in diameter. 

 Barren Oak lands, Kentucky and Ten- 

 nessee. 



C. digitata. A distinct-looking glau- 



cous perennial herb, 2 or 3 ft. high, with 

 reddish-purple flowers in summer ; it is 

 not so showy as the other kinds. 



C. involucrata is a charming dwarf 

 prostrate perennial, with large violet- 

 crimson flowers 2 in. in diameter. It is 

 excellent for the rock-garden, as it bears 

 a continuous crop of showy blossoms from 

 early in summer till late 'in autumn. It 

 has the best effect when allowed to fall 

 over the ledge of a rock. California. 



C. macrorhiza alba is a pure white 

 form of a kind with purplish-carmine 

 flowers, and erect stems, from i^ to 2^ ft. 

 high, with a corymbose raceme of flowers. 

 It occurs in several shades of colour, from 

 rosy-purple to pale rose and white, and 

 sown early it will bloom the first year. 

 South-western States of N. America. 



C. Papaver, figured in The Garden, has 

 a trailing habit, and flowers incessantly 

 from early summer until late autumn. 

 The flowers are of a bright purple-red, as 

 large and somewhat resembling those of 

 our common field Poppy, hence the 

 name. 



C. pedata is one of the prettiest species. 

 A perennial, with trailing stems bearing 

 lobed foliage, and handsome crimson 

 flowers, fully 2 in. in diameter. When 

 sown early the plants bloom the first 

 season, and continue in flower until late 

 in autumn. In dry soils the roots survive 

 our average winters. It succeeds best 

 in dry soils. The varieties nana and 

 compacta are pretty dwarfer varieties. 



CALLISTEPHUS (China Aster]. 

 Among the many annuals now in cultiva- 

 tion China Asters (C. chinensis) are among 

 the best, and when well grown and cared 

 for they do as much to render a garden 

 gay during summer and autumn as any 

 annual plant. To see them in their beauty, 

 however, they must be grown in masses, 

 and well cultivated not at any stage left 

 to haphazard or poor culture. 



VARIETIES. China Asters may be 

 classed according to height, habit, 

 character of flower. Tall Asters com- 

 prise the fine Paeony-flowered, the tall 

 Chrysanthemum, the Emperor, the tall 

 Victoria, the Quilled, and a few others. 

 Kinds of medium height are the dwarfer 

 forms of the Victoria, the fine Cocardeau, 

 the Rose, and the Porcupine. The dwarf 

 forms comprise the short Chrysanthemum, 

 the dwarf pyramidal, and specially the 

 dwarf bouquet, which is one of the most 

 beautiful for pot culture. The best bedding 

 kinds are the medium-growing Victoria, 

 the Rose, and the dwarf Chrysanthemum, 

 as these vary from 9 to 12 in. in height, 

 and form good bunches of bloom on each
