DENTAKIA DI ANTHUS. 



tance than tlie species. Additions are 

 being yearly made to the number by 

 nurserymen who cultivate florists' 

 flowers, and have usually a good selec- 

 tion of fine kinds. These Delphiniums 

 are of the highest importance in the 

 flower-garden, where they may be 

 used in lines and in mixtures, in the 

 mixed border of which they are some 

 of the finest ornaments, and, in a 

 word, for every use to which the 

 most beautiful perennials may be put. 

 They thrive best in rich light soil ; 

 and if, after flowering in summer, 

 they are cut down to near the ground, 

 they will again bloom vigorously by 

 autumn. All are easily increased by 

 division in winter, or early spring. 

 The following are excellent kinds : 

 Alopecuroides, Belladonna, Barlowii, 

 Hendersoni, La Belle Alliance, Scha- 

 myl, Wheeleri, William Pfitzer, Ranun- 

 culceflorum, Delight, Hyacinthiflorum, 

 Magnificum,Keteleeri, Heine des Delphi- 

 niums, Madame Chate, Hebe, and Bicolor 

 grandiflorum. 



Dentaria bulbifera (Bulb-bearing D.) 

 An interesting perennial, bearing 

 bulbils in the axils of its leaves, as in 

 I/ilium bulbiferum ; 1 to 2 ft. high. 

 Flowers, in spring ; purple, sometimes 

 nearly white, rather large, produced 

 in a raceme at the top of the stem. 

 Leaves, lower ones pinnate, with 5 or 

 7 segments ; upper ones undivided or 

 with few segments ; segments 1 to 2 in. 

 long, lance-shaped, toothed or entire, 

 tapering at the base. Europe, Asia, 



and Britain. Borders, and fringes 



of shrubberies in half-shady positions, 

 and in sandy vegetable soil. Divi- 

 sion and seed. 



Dentaria digitata (Showy Toothwort.) 

 A very handsome dwarf kind, 

 about 12 in. high. Flowers, in April; 

 rich purple, in flat racemes at the top 

 of the stem. Leaves, stalked, pal- 

 mately cut into 5 oblong-lanceolate, 

 pointed, deeply serrated segments. 



France, Italy, and Switzerland, in 



shady woods. Half-shady borders, 



margins of beds of American plants, 

 or among low shrubs near rockwork, 

 in rich light and moist soil. Divi- 

 sion. 



Dentaria pinnata (Pinnate D.) A 

 stout species at once distinguished by 

 its pinnate leaves ; 14 to 20 in. high. 

 Flowers, from April to June ; large, 

 pale purple, lilac, or white, in a 

 terminal cluster. Leaves, few, near 

 the top of the stem, alternate, stalked, 

 pinnate ; leaflets 5 to 7, lance-shaped, 

 acute, smooth, irregularly toothed, 

 pale underneath. Switzerland, in 



mountain and sub-alpine woods. 



Fringes of shrubberies and half-shady 

 spots, in rich light earth. Careful 

 division of the thick scaly roots. 



Dianthus alpinus (Alpine Pink). A 

 rare and beautiful mountain pink, 

 3 or 4 in. high. Flowers, in summer ; 

 deep rose spotted with crimson, large, 

 solitary on each stem, so freely pro- 

 duced as to hide the leaves ; petals 

 crenated. Leaves, green, oblong- 

 linear, obtuse. Alps of Austria. 



The rock-garden, in exposed spots, in 

 light, fibry, gritty, or sandy loam. 

 Where plentiful enough, and where it 

 thrives freely, it should be used on 

 the margin of the choice border. I 

 have seen it attain great beauty as an 

 edging to small beds of American 

 plants, in sandy peat. Seed and care- 

 ful division. 



Dianthus barbatus (Sweet William). 

 One of our most popular old garden 

 flowers, 1 to 2 ft. high. Flowers, in 

 summer ; variously coloured, from dark 

 purple to white, in dense cymes; petals 

 bearded ; scales of the calyx ovate, 

 awl-shaped, about equalling the tube. 

 Leaves, broadly-lance-shaped, nerved. 

 There are many varieties, both single 

 and double. Various parts of Central 

 and Southern Europe. Borders,
