Trees and Shrubs. 



PRUNU5 TRILOBA. 



Under the common name of the double 

 flowering plum, this shrub is deservedly 

 well kno*n to most northern gardeners. 

 Its almost absolute hardiness is an essen- 

 tial element in its favor. Oncein a while, 

 duringwintersofextremecold.it ma}- lose 

 its flower buds, but the damage ends 

 there. It is a native of China. While 

 those usually cultivated have double pink 

 flowers, a single-flowered form is known. 

 In Gardening February 15, 1897, there 

 is illustrated a very fine specimen grown 

 in the natural way, that is, on its own 

 roots and in shrub form. Mr. Temple 

 describes it as being fifteen feet in diame- 



ter and eight to ten feet high, and as 

 being planted some twelve years. 



The two specimens here illustrated are 

 what are termed standards, that is, grown 

 to a tree form. Some shrubs like the 

 Hydrangea paniculata grandiflora, may 

 be grown as standards, while still on 

 their own roots, by allowing, at first, 

 only one stem to grow, which is trained 

 up straight, with no side branches except 

 at the top. Generally, however, stand- 

 ards are produced by budding or grafting 

 on some strong growing species of the 

 same or an allied genus. The specimens 

 illustrated are grafted at a height of four 

 feet from the ground. The width and 

 height of the head of the one at the left is 

 six teet. 



As a rule standards are not as long 

 lived as when naturally grown, as in the 

 latter case the shrub renews itself by new 

 shoots from the roots, which standards 



cannot do, therefore morecare is required 

 in growing this form, especially in endeav- 

 oring to retain a dense head of bloom and 

 leaf. This denseness is easily retained in 

 shrub form, as the renewed growth from 

 the bottom produces the new wood that 

 gives the most flowers and leafage. The 

 heads of standards may be kept in verv 

 fair form, by due attention to cutting in 

 immediately after blooming. These spec- 

 imens were exhibited by a Holland firm 

 on the Wooded Island at the World's 

 Fair, and were transferred to Egandale 

 in the spring of 1894. W. C. Egan.

This doubly handsome tree should find 

 a place in all parks and private grounds 

 making any pretence whatever to a selec- 

 tion of trees, the flowers and foliage being 

 both unique. It is almost impossible to
