HARDY PERENNIAL PLANTS. 18t 



CERASTIUM BIEBERSTEINII A dwarf plant with a dense mass of 

 growths; flowers pure white: in bloom during May. The leaves are 

 very woolly, giving the plant a whitish appearance all the year round. 

 It stands our hot Summers better even than the well-known C. tomen- 

 tosum (Snow in Summer.) This is a species with smaller and lighter 

 colored foliage. Both are used for edging in beds or borders. The 

 plants may be divided very early in the season with or without roots 

 and replanted with long stems, deep in the soil, well firmed, and kept 

 moist until they begin to grow. C. Biebersteinii is easily raised from 

 seeds. 0. grandiflora is a green-leaved species well adapted for growing 

 in dense carpet-like masses over rocks. 



CHEIRANTHUS CHEIRI (Wallflower) A plant much grown in Europe, 

 where the climate is very favorable to its perfect development. In the 

 warmer parts of America its period of blooming is but a short one. The 

 seeds are sown in April, and as soon as large enough the seedlings are 

 planted out where they are to flower the following Spring. There are 

 many fine double forms, some of which have varietal names. Double 

 flowering kinds can be raised from seed. The colors of the flowers are 

 yellow, and reddish brown. 



CHELIDONIUM MAJUS FLORE=PLENO (Double Celandine) A reliable 



plant for half-shaded positions in woods. It is especially at home 

 among damp rocks, growing in vegetable humus. In such positions it 

 will reproduce itself from seeds. The double form is smaller growing 

 than the single-flowered plant. The foliage of both has a bright green 

 appearance for the greater part of the Summer. 



CHRYSANTHEMUMS, 



For nearly ten months out of the twelve Chrysanthemums are so 

 little seen that when the flowers are in season they are eagerly welcomed 

 by the flower-buying public as a change from the blossoms of Spring 

 and Summer. There may be a change from the stiff and artificial look- 

 ing flower, which is grown on single stems, to the more natural looking 

 spray with smaller flowers; but it is safe to say that the Queen of 

 Autumn will remain popular in some shape or other for a long time to 

 come. Within the last eighteen years the cultivation of this flower has 

 made rapid strides. The size of the blooms is due to this improved cultiva- 

 tion quite as much as to an improvement in the varieties by selection of 

 sports and cross breeding during that time. Many good kinds have 

 been raised, but these kinds, when grown according to old methods, do 

 not show the wonderful improvement that is claimed for them. Indoor 

 bench culture and growing one flower to a plant is the means by which 

 the flowers are developed to their utmost size. 



Stock Plants Selected roots for this purpose should be heeled in on 

 the bench of a house where they can be kept cool; a temperature high 

 enough to keep out frost is best. If such accommodation can not be 

 spared the next best place is a frame around which stable bedding is
