i84 PLANT CULTURE 



CLEMATIS. During July and August one of the most useful 

 plants for producing white flowers is the herbaceous Clematis, 

 known as C. recta. It grows from 2 to 3 feet high and if in deep, 

 rich soil the quantity of flowers to a plant is very large. In C. 

 heraclemfolia (lubulosa) and C. Davidiana we have two blue-flowered 

 species from China. The last named is fragrant. They are reUable 

 plants for the herbaceous border, growing about 2 feet high. 



Propagation. They are all increased from seeds sown as soon 

 as gathered ; also from division of the crowns, and by cuttings taken 

 from the plants before coming into flower. 



COREOPSIS. C. lanceolata and C. I. grandiflora are yellow- 

 flowered composites, much used for Summer cut flowers. C. verti- 

 cillala is of little service for cutting, but owing to the finely divided 

 foliage it is a desirable border plant. 



Propagation. Old plants may be divided, but they are best 

 raised from seeds, and the young plants put out early w^here they 

 are to bloom. 



DELPHINIUM (Larkspur). D. grandiflorum and D. formosum 

 have numerous fine varieties, which are much grown for cut flowers. 

 The D. grandiflorum, 2 to 3 feet high, is one of the most stately of 

 the Delphiniums. Its striking foliage remains beautiful throughout 

 the whole growing season. It can be massed in the hardy border 

 as close as 2 feet, but produces a fine effect when 4 feet apart. On 

 account of its height it is usually planted well back in the border. 

 The D. formosum is the most permanent form for naturalizing, 

 being the hardiest. The species are numerous and there are superb 

 hybrids catalogued by dealers, most of them being choice border 

 perennials requiring deep, rich soil. 



Propagation. They are propagated principally by cuttings 

 of the young growths in early Spring, from seeds sown about the 

 beginning of March, and by division of the roots when dormant in 

 Autumn or late Winter. 



DIANTHUS (Carnation. Pink). There are nearly a hundred 

 distinct species, many of which are in cultivation. Most of them are 

 desirable as border or rockery plants. They usually make dense 

 tufts of grassy-like growths. Nearly all have attractive flowers. 

 D. barbatus is the Sweet William. Good strains are procured from 

 seed. D. ccBsius (Cheddar Pink) stands our hot Summers well. A 

 useful species for the rockery. D. plumarius (Common, Grass, or 

 Garden Pink) is a universal favorite, being used as edging for beds.
