GOOD TREES AND SHRUBS 221 



known also as C. multiflora, is of excellent growth, very free, and bears 

 crimson fruit. O. tanacetifolia (Tansy-leaved Thorn) is very beautiful, 

 having much cut grey leaves and sweet-scented flowers and yellow 

 fruits. It blooms quite late. C. Carrieri is free in growth and very 

 ornamental. Its large orange-red fruits are showy and hang upon 

 the tree generally until spring. G. Douglasi is vigorous, flowers 

 early, and has dark fruits. The Washington Thorn (C. cor data) is 

 a conspicuous autumn shrub, wtih great corymbs of white flowers late 

 in spring and showy fruit in autumn. Amongst the numerous varieties 

 of the Common Thorn the following are especially good: Lucida, flowers 

 double white ; flore pleno coccinea, flowers double scarlet ; flore pleno 

 rosea, flowers double, rose coloured ; flore puniceo, flowers single red ; 

 atrofusca, weeping habit, flowers white. Paul's Scarlet is a very bright 

 kind. G. Pyracantlia (Evergreen Fire Thorn) is a well-known shrub, 

 usually planted against a wall, and is one of the most attractive of 

 shrubs for this purpose. The berries are borne in clusters, and if birds 

 are kept off, will remain fresh for the greater part of the winter. 



Cytisus (Broom). This is a fairly large group of shrubs, with pea- 

 shaped flowers. Ordinary soil suits them, and they succeed well in dry 

 situations. Those mentioned are perfectly hardy and satisfactory in all 

 ways. G. biflorus is of sturdy growth and very free-flowering. Its 

 bright yellow flowers are borne in clusters. The Black Cytisus (G. 

 mgricans), from Austria, bears rich yellow flowers in erect racemes 

 towards midsummer. G. pr&cox, a hybrid between C. albus and C. 

 purgans, is a grand shrub for massing. In habit it is less vigorous than 

 the White Broom. The flowers are sulphur yellow. G. capitatus is a 

 much branched bush, four feet high, with bright yellow flowers at the 

 points of the growths. G. purgans is a charming free-growing and free- 

 flowering dwarf shrub. Its flowers are bright yellow. G. purpureus is 

 another good dwarf spreading shrub, which begins to blossom in May and 

 keeps up a succession of dull purple flowers until autumn. As it is of 

 procumbent habit it deserves a place in the rock-garden. C. kewensis is 

 another rock-garden Cytisus, raised by crossing G. Ardoini with G. albus. 

 It is of creeping habit, and bears a profusion of cream-coloured flowers. 

 G. albus (White Broom), G. scoparius (Yellow Broom) are too well 

 known to need description, and andreanus, a variety of the last named, 

 also known as Genista andreana, is very showy and blooms profusely. 



Groups of the White and Common Broom are very beautiful and are 

 the shrubs to plant in rough places, where one wants to preserve a wild 

 free growth. 



Daboecia polifolia (St. Dabeoc's Heath), and its varieties, alba and 

 bicolor, are exceptionally pretty free-flowering dwarf evergreens, which 

 seem to flourish best in damp peaty soil. They are just the kind of 

 shrubs for planting in masses at the foot of the rock-garden, as their 

 neat habit fits them for such a position. The drooping flowers of each 

 are borne in erect terminal racemes in summer and autumn. The type 

 has crimson-purple flowers ; alba, white ; and bicolor, white and purple on 

 the same plant. 



Daphnes. These are low-growing, deciduous, and evergreen shrubs,
