is a pretty sight, with its yellow flowers and elegant 

 foliage, and its white variety is even more attractive. 

 C. bracteata, C. nobilis and C. solida are worth growing 

 in rocky ground. 



Dianthus. — The Alpine Pinks are more likely to 

 prosper on stony banks than in the border, and the 

 Cheddar Pink, D. coesius, grows and flowers freely on 

 old wall-tops. Pink seed sown along cliff ledges where 

 gritty soil has been scattered will be the means of 

 creating a charming picture later on. D. Athinsoni is a 

 striking Pink of glowing crimson, and Napoleon III. is 

 a double form almost as bright in colour. D.fragrans 

 is a perfumed flower with feathered petals, and in D. 

 superbus the petals are still more divided. 



Dodecatheon. — American Cowslip. D. Meadia is a 

 graceful plant bearing several rosy-purple drooping 

 flowers with reflexed petals on stems a foot or so in 

 height. There are several varieties of this plant. A 

 rich and porous loam is best suited to its requirements, 

 and it should be planted in a sheltered and partially 

 shaded position. 



Dondia epipactis. Syn. Hacquetia. — A pretty little 

 dwarf-growing plant, bearing in the spring quaint 

 pale-green flowers with yellow centres. Succeeds 

 best in a partially shaded position. 



Draba. — Dwarf Alpine plants bearing white or yellow 

 flowers which, in the case of D. gigas, are almost an inch 

 in diameter. They form compact cushions of foliage 

 spreading in tufts over the ground, and are most satis- 

 factory when planted in crevices between rocks, where 

 they will get the full summer sun and be free from 

 stagnant moisture at the roots during winter. 



Dry as. — D. Drummondii is a dwarf trailer bearing 

 yellow flowers on stems six inches in height. It prefers 

 a compost of moist, peaty loam. D. octopetala does well 

 in the full sunshine, covering the ground with close-
