DIANTHUS 



DICENTRA 



11. alpinus, Linn. Very dwarf, the 1-fld. stems rarely 

 reaching more than 3-4 in. high, more or less prostrate: 

 foliage dark shining green : fl. 1 in. or more across, deep 

 rose or purplish and crimson spotted, a darker ring 

 around the eye. Russia to Greece and Swiss Alps. B.M. 

 1205. Gn. 26:455; 47, p. 292; 45, p. 53. -One of the choic- 

 est of alpine and rockwork plants. 



BBS. Calyx-bracts leafy and spreading. 



12. glacialia, Haenke. Three to 4 in. high, the stems 

 tufted and usually 1-fld. : Ivs. green, narrow-linear and 

 pointed, somewhat serrulate: fls. small and odorless, 

 red-purple; the petals toothed. Mts. of S. Eu. G.C. II. 

 21:809. A pretty species, but difficult to establish. 

 Grown among alpine plants. 



13. CMnensis, Linn. (D. Sintnsis, Hort.). Fig. 702. 

 Perennial, cespitose, glabrous, more or less creeping at 

 base: stem forking, angled and more or less grooved, 

 pubescent: Ivs. broad and nearly flat or slightly trough- 

 shaped, 3-5-nerved: fls. large, solitary or more or less 

 clustered, pink or lilac; the petals (at least in the wild) 

 barbed or hairy towards the base; calyx-bracts 4, in 

 some cult. vars. short. China and Japan; but recent au- 

 thorities consider a European Pink to be but a form of 

 it, and thereby extend its range west to Portugal. The 

 Amoor Pink (D. dentdsus, Fisch.) is a form known as 

 var. macrosepalus, Franch.: it is a hardy border plant, 

 1 ft. high, with bright red fls. and a spot at base of each 

 petal. D. semperflorens, Hort., is a hardy perennial 

 form, 12-18 in., with silvery foliage and deep pink, red- 

 eyed, fragrant fls. D. Chinensis has given rise to a 

 beautiful and variable race of garden Pinks, var. Hed- 

 dewigi, Regel (D. Htddewigi, Hort.). These are ex- 

 tensively grown from seeds, and are practically an- 

 nuals, although plants may survive the winter and give 

 a feeble bloom in the spring in mild climates. The 

 flowers are scarcely odorous. They are single and 

 double, of many vivid colors; and many of the garden 

 forms have bizarre markings. In some forms, var. la- 

 ciniatus, Regel (D. laciniatus, Hort.), the petals are 

 slashed and cut. D. imperialis, Hort., is a name applied 

 to a strain with strong habit and rather tall growth, 

 mostly double. C. diadematus, Hort., is another garden 

 strain. D. Cincinnatus, Lem., is a red form with 

 shredded petals. I.H. 11:388. D. hybridus, Hort., is 



13:1380-1. Gn. 49:1051. The garden Pinks are of 

 easy culture. Seeds may be sown in the open where 

 the plants are to stand, but better results are obtained r 

 at least in the north, if plants are started in the house. 



703. Dicentra spectabilis-Bleeding Heart (X %). 



another set. This name (D. hybridus) is also applied 

 to a dentosus-like form, which some regard as a hybrid 

 of dentosus and some other species. For portraits of 

 garden Pinks, see B.M. 5536; F.S. 11:1150; 12:1288-9; 



704. Dicentra formosa (X %). 



Plants bloom after the first fall frosts. They grow 10- 

 16 in. high, and should be planted 6-8 in. apart. They 

 are very valuable for borders and flower gardens. 



14. latifdlius, Hort. Perennial, 6-12 in. high, of doubt- 

 ful origin, but in habit intermediate between D, Chi- 

 nensis and D. barbatus. Fls. large, double, in close 

 clusters or even heads: Ivs. oblong-lanceolate. A good 

 border plant. 



D. mscordalis is a name which once was advertised by Man- 

 ning, but is not now in the trade. The seed was obtained from 

 an English firm. It is probably a garden form of some old 

 species. L. H. B. 



DIClSNTRA (Greek, dis, kentron, two-spurred, but 

 originally misprinted Diclytra, and then supposed to be 

 Dielytra). Fumariacece. A genus of charming hardy 

 perennial plants with much cut foliage, and rose, white 

 or yellow fls. of interesting structure. The Squirrel 

 Corn and Dutchman's Breeches are two of our daintiest 

 native springtime flowers, and the Bleeding Heart is 

 one of the choicest memories of old-fashioned gardens : 

 it is also the most widely cultivated of all the plants of 

 this delightful order. Though long known to herbaria, 

 plants of Bleeding Heart were not introduced to western 

 cultivation from Japan until the late forties. Robert For- 

 tune saw it on the Island of Chusan, where he also got 

 Diervilla rosea and the epoch-making "Chusan Daisy," 

 the parent of pompon Chrysanthemums. The first live 

 plants seen in England flowered in May, 1847. It rapidly 

 spread into every garden in the land, and is now rich 

 in home associations. It is an altogether lovely plant. 

 There are about 15 species of Dicentra, mostly N. 

 American. Sepals 2, scale-like : petals united into a 

 2-spurred or heart-shaped nectariferous corolla : stamens 

 diadelphous. 



Dicentras are easily cultivated in borders and wild gar- 

 dens. Two kinds can be readily secured from the woods 

 in the E. Try to reproduce the natural conditions, espe- 

 cially the degree of shade, They like a rich, light soil. 

 Prop, by dividing crowns or roots. It is a singular fact 

 that the forcing of Bleeding Hearts, though practically 

 unknown in America, is said to be commoner in England 

 than outdoor culture. According to Nicholson, the foro-
