HARDY SHRUBS 303 



Propagation. Cuttings root freely, under cool treatment, late 

 in Summer. 



CITRUS. As a dwarfing stock C. trifoliata is used extensively 

 for budding and grafting the different varieties of Oranges, and for 

 a hedge plant, one that will make an almost impenetrable barrier, 

 scarcely any other subject will answer so well. But its usefulness is 

 yet by no means exhausted. As an ornamental shrub it makes quite 

 an effective appearance early in the season, before the leaves appear, 

 when covered with its pure white flowers, which are usually an inch 

 across. In late Summer and Fall the branches are loaded down 

 with its golden fruit. During some seasons this species bears two 

 crops of flowers — the first in Spring, the second along about the 

 month of August. The second crop of fruit fails to ripen before 

 cool weather. 



Propagation. Its propagation is effected by seeds, of which 

 there is a plentiful supply; sown in the Fall out of doors, every 

 seed will germinate after good weather sets in. 



CLERODENDRON. A very handsome, free-flowering Japan- 

 ese species, C. Irichotomum, thoroughly hardy in the Middle Atlantic 

 States; although annually killed to the ground farther north, it 

 makes strong growths, and on these it blooms freely. The flowers 

 are white with a dark red calyx. C. foelidum is not as hardy as the 

 above. The crowns, if they can be saved, will flower splendidly 

 from herbaceous stems. It is one of the best shrubs for the Southern 

 States. It sends up many shoots from underground stems. 



Propagation. Propagation is accomplished by cutting up and 

 sprouting the roots. The plant seems to delight in rather dry soil. 

 In dry weather, when other shrubs suffer for want of water, this 

 one is always fresh and green; but probably this is caused by the 

 roots going deep into the soil. To increase C. fwtidum in quantity 

 the roots and underground stems should be dug up, cut in small 

 pieces, and started indoors early in Spring. 



CORNUS (Dogwood). In the Southern States, C.florida, the 

 Flowering Dogwood, grows sometimes 30 to 40 feet high; farther 

 North it is a shrub 10 to 15 feet high. The flowers are small, green- 

 ish yellow; the bracts are very large and pure white. It blooms in 

 early Spring before the leaves are developed. In Autumn a well 

 fruited bush, with its red foliage, is a most beautiful object. C. f. 

 rubra is a rosy pink flowered variety of recent introduction, well 

 worthy of cultivation; both it and the type should be planted in
