HARDY PICTORIAL TREES. 267 



Coronilla Emerus. Height, 6 feet. This is a pretty 

 dwarf shrub, the flowers yellow, tipped with red, produced 

 in May and June. It is very hardy, thriving in any soil. 



Cratcegus Oxyacantha punicea (the Scarlet Thorn). 

 Height, 1 5 feet. No plant is more beautiful in early spring, 

 the dark red flowers being produced in magnificent pro- 

 fusion. The species and varieties of Crataegus are almost 

 endless, and nearly all are desirable when space admits of 

 their introduction. The best for ornamental planting are 

 the double white (C. Oxyacantha fl.-pl.), the double pink 

 (C. O. punicea fl.-pl.), and the double crimson (C. O. coccinea 

 fl. pi.), the last named promising to eclipse all others in

 flowers tipped with pink, also very beautiful. The common 

 Laburnum (C. Laburnum, height, 20 feet) belongs here, 

 and there are many dwarf-growing varieties of great 

 beauty, ranging in height from I to 4 feet ; of these 

 nigricans, patens, purpureus, purpureus flore-albo, elon- 

 gatus, supinus, and capitatus, may be regarded as the 

 best.

 Both the white and pink varieties of this plant are 

 desirable on account of flowering in mid-winter. 



Deutzia gracilis. Height, 2 to 3 feet. A pretty dwarf 

 shrub of free hardy growth thriving in any soil ; admirably 

 adapted for the front of shrubberies. The white flowers 

 are freely produced in early spring. D. scabra is similar 

 in character, although of larger growth. D. crenata flore- 

 pleno is very handsome, the flowers white, often tinged 

 with rose colour. All these are excellent for forcing. 



Forsythia viridissima. Height, 4 feet. The flowers of 

 this plant, which are greenish yellow, appear in great
