Iberbaceous plants* 333 



leafy sterns, pendulous, almost cylindrical, blue. Neat in 

 moist places in rockeries. C. Rainerii, dwarf, two or three 

 inches ; leaves ovate, hairy ; flowers mostly solitary, erect. 

 O. Waldsteiniana, dwarf ; leaves small, cordate ; stems four 

 or five inches high, bearing one or more erect, violet-blue 

 flowers. All these are suitable for rockeries, but enjoy 

 half shade and moisture and a light, well-drained soil. The 

 common harebell (C. rotundifolia) is one of the prettiest of 

 all bell-flowers. The stems are nearly always simple, but it 

 often forms rich tufted masses ; flowers solitary, drooping, 

 blue or white. Grows in rocky, open woodlands, and is 

 especially desirable for naturalizing in lawns and grassy 

 openings among trees and shrubs. Another fine species for 

 naturalizing is C. rapunculoides. 



Chinese Bell-flower, Platycodon grandiflorum. This is 

 the largest flowering species of the family ; stems somewhat 

 branching; leaves ovate-lanceolate, large and handsome; 

 flowers blue, several inches across, solitary or in small clus- 

 ters at the top of the branches. Height about two feet ; 

 flowers late in summer. There is a white variety. P. 

 Mariesii is a dwarf and very floriferous form. Both are 

 very fine plants for borders and rockeries ; the best bell- 

 flowers for small gardens. 



THE PYKOLA FAMILY. 



Wintergreen, Pyrola. A genus of several small ever- 

 green woodland flowers. They grow in partial shade in 

 leaf soil, chiefly in sandy ground, and are excellent for 

 planting in thickets and shrubberies among other wood- 

 land flowers. Most common are: P. chlorantlia, flowers 

 greenish- white, scented, borne in umbels on simple scapes
