4-5 ft. high. It has large tuber- 

 ous, Parsnip-like roots, circles of 

 toothed leaves, and beautiful, 

 bell-shaped flowers up to 4 in. 

 across, white stained with lilac- 

 purple and deeper veins (fig. 

 230). This noble plant is quite 

 hardy in most parts of the king- 

 dom, and may be raised from 

 seeds sown in cold frames or in 

 a warm greenhouse. Owing to 

 the great roots it is necessary 

 to have the soil deeply dug and 

 well manured to secure the best 

 results. 



Ourisia coccinea. A hand- 

 some Chilian rock plant about 

 9 in. high, with oval coarsely 

 toothed leaves, and drooping 

 scarlet flowers from May to Sep- 

 tember. It likes moist peaty 

 soil, and partially shaded places 

 and warm, being a little tender. 

 Oxalis. A large genus of 

 tuberous-rooted plants from 

 various parts of the world, easily 

 Some kinds are grown in greenhouses, 

 but several are fairly hardy. 

 Among these latter one of the 

 best is enneaphylla (tig. 231), 

 from the Falkland Islands, with 

 tubular white (or rose) flowers 

 in summer. It likes moist shady 

 positions in the rock garden, and 

 is increased by separation of the 

 offsets. A closely related species 

 is adenophylla, which has larger 

 pink or rose flowers. 0. crenata 

 and 0. Deppei are valued for 

 their edible tubers, but there are 

 about 200 other species having 

 a general resemblance in blos- 

 som, the colours of which are 

 either white, rose, or yellow. 

 Paeonia (P^EONY). Although there are many distinct species of Pseony 

 known in botanical collections, only one or two are grown extensively
