GOOD TREES AND SHRUBS 219 



also for its small, sweet-scented, white, orange-like blossoms, which 

 are borne along the spiny branches. It is slow in growth, and 

 should, if possible, be planted in small groups on the turf, selecting 

 of course a sunny position so as to insure thorough ripening of the 

 wood. It succeeds best in turfy loam, with which has been incorporated 

 a quantity of leaf-mould. Good drainage is of much importance, be- 

 cause it fails when the roots travel into sour soil. 



Glerodendron trichotomum. Here we have another autumn- 

 flowering shrub or small tree, introduced a hundred years ago. It is 

 vigorous and distinct both in foliage and in flower, its ovate deep green 

 leaves changing in autumn to shades of orange and red, and its sweet- 

 scented flowers appear abundantly in terminal cymes, the conspicuous 

 purple calyces affording additional beauty. It delights in a rich, well- 

 drained soil, and protection from piercing winds is essential. 



Clethras. Few hardy Clethras are cultivated in this country, still 

 they are exceedingly ornamental, easily grown, and all have fragrant 

 flowers. They grow well in fibrous loam, but prefer a moist, peaty soil. 

 C. alnifolia (the Alder-leaved Pepper-Tree) is rarely more than five feet 

 high, and bears a great profusion of small white flowers towards mid- 

 summer. The variety tomentosa should be grown for its flower display. 

 It is of similar habit to the type, but the flowers are bigger and borne 

 at least three weeks later. 



The Coluteas (Bladder Sennas} are very accommodating shrubs, as 

 there is scarcely a position in which they refuse to grow. No soil, how- 

 ever poor, comes amiss to them, as they grow freely and flower profusely 

 in wet as well as in dry situations. They are also excellent shrubs 

 for smoky districts. It is a good plan to cut them hard back every 

 spring, as vigorous growth follows close pruning. There is a profusion 

 of bladder-like seed-pods, at first red, then changing to orange-yellow in 

 autumn. 



The Dogwoods (Cornus) are deciduous shrubs of free growth. They 

 comprise silver, gold, and green-leaved forms, and some, like C.florida and 

 G. Kousa, are valuable flowering shrubs, and 0. alba is one of the most 

 effective of red stemmed shrubs in winter; it is an excellent kind 

 for planting along the water margin, as the reflection of the bark in 

 the water in winter makes warm colouring in the garden. Sibirica is 

 a good variety. Spathi is a brilliant golden-leaved shrub, and does not 

 burn in hot suns as in the case of the majority of yellow-leaved shrubs. 

 Its delicate pale green leaves are marked with yellow and irregularly 

 bordered with a deeper shade. C. macrophylla has bright green leaves, 

 which in autumn are heavily shaded with red. It is conspicuous in 

 early summer when bearing its large clusters of white flowers. The 

 Cornelian Cherry (C. Mas) is a small growing tree of erect bushy habit 

 with slender branches, and in February bears clusters of small yellow 

 flowers. It grows freely in dry soil. 



The genus Corylopsis contains several uncommon deciduous shrubs 

 of much merit ; they are quite hardy, dwarf, and delightfully free, well 

 deserving a place against a west wall, as the flowers are seen there to 

 better advantage than when on plants in the open shrubbery. C. spicata,
