FLOWERING TREES AND SHRUBS 197 



is a very free-growing shrub, of perfect hardihood, and one 

 of, if not the best for general planting. 



The above two species are, so far as is at present 

 known, the hardiest in cultivation, although there are 

 many kinds that will succeed well under very favourable 

 conditions, and particularly when planted by the seaside. 

 Other half-hardy species might include V. salicifolia 

 (Willow-leaved Veronica), with long, narrow leaves, and 

 white or purplish flowers; V. ligustrifolia (Privet-leaved 

 Veronica), with spikes of feathery-white flowers ; V. speciosa, 

 with erect spikes of purplish-blue flowers ; and V. Ander- 

 soni, a hybrid form, with spikes of bluish-violet flowers. 

 V. hulkeana is another desirable Bpecies. 



The dwarf or alpine species might include V. cupres- 

 soides, with Cypress-like foliage, V. Lyallii, V. carnosula, 

 and others, but such hardly come within our scope. 



The Veronicas thrive best in light, loamy soil. 



Viburnum (Caprifoliaceae), 



Viburnum acerifolium. — Dockmackie. New England to 

 Carolina, 1736. This is one of the handsomest members 

 of the family, being of slender growth and compact and 

 neat in habit. It grows to fully 4 feet in height, and is 

 well supplied with neatly three-lobed leaves, these in the 

 autumn turning to a deep crimson. The white or yellowish- 

 white flowers, too, are highly ornamental, being borne in 

 fair-sized clusters. It is a very desirable and beautiful 

 plant, quite hardy, and of free growth in any fairly 

 rich soil. 



V. Awapukii. — Japan, 1842. This is another rare and 

 beautiful plant, of neat habit, and bearing an abundance 

 of showy white flowers, that are, however, seldom produced 

 in this country. 



is V. Carlesh. — Corea, 1902. This is a recently introduced 

 species with ovate leaves upwards of 2 inches long, with
