266 THE NEW GARDENING 



The Hollies, Ilex Aquifolium varieties, are a numerous 

 band. The variegated sorts, such as the Silver Milkmaid 

 (argentea medio-picta) ; Golden Queen, Waterer's 

 Golden, Golden Milkmaid (aurea medio-picta), aurea 

 marginata and Handsworth Silver, are the most popular, 

 with the possible exception of Hodginsii, which has very 

 large oval leaves. The Golden-fruited variety fructu- 

 luteo is interesting. The Hedgehog Holly is I. ferox. 



The Laburnum has been mentioned in a previous 

 chapter, and the Scotch, L. alpinum, recommended in 

 preference to the common, L. vulgare, owing to its bear- 

 ing longer racemes of bloom ; it flowers a little later in 

 spring. A hybrid called Watereri, said to have been 

 raised by crossing the common and Scotch Laburnums, 

 is good, as it produces very long racemes late in spring. 

 Perhaps most tree-lovers are familiar with the peculiari- 

 ties of the graft-hybrid variously known as Laburnum 

 Adami and Cytisus Adami, which was raised by a French 

 florist in 1825 by grafting Cytisus purpureus on to 

 Laburnum alpinum. This has been known to produce 

 in alternate years : (i) Cytisus purpureus and yellow 

 Laburnum ; (2) Cytisus purpureus, yellow Laburnum 

 and a purple Laburnum alpinum, the last identical with 

 Laburnum alpinum except in colour. In other years 

 only one form appears. It is singular and interesting 

 owing to its variability, but is not otherwise desirable. 



The Sweet Gum, Liquidambar styraciflua, is a deciduous 

 tree which is admired because of the brilliant colour which 

 the leaves assume in autumn. 



The Tulip Tree, Liriodendron tulipifera, attains to the 

 dimensions of a forest tree in rich soil, and may be 

 planted on a large lawn. When the Tulip-like greenish 

 yellow flowers are borne freely it is very handsome. 

 There is a variety with yellow in the leaves called aurea.
