ORNAMENTAL GARDENING. 



In previous annual reports of the Horticultural Division, and in bulletins, con- 

 siderable information has been given by the writer in regard to trees, shrubs and 

 herbaceous plants tested at the Central Experimental Earm. Short descriptions 

 have in many cases been published of varieties considered best for ornamental plant- 

 ing and, in some cases, cultural dir ctions based on experience at Ottawa have been 

 given. 



In 1897, lists were published of one hundred of the most ornamental hardy trees 

 and shrubs, and also one hundred of the best herbaceous perennials. In 1898, an 

 additional list of good perennials was given. In 1899, a list was published of some 

 good low-growing flowering shrubs, and also an additional list of good perennials. In 

 1900 there was given a list of the best hardy, woody, and annual climbers. In 1902, a 

 list of best spring flowering" perennials. In 1903, a list of deciduous trees, shrubs and 

 climbers with attractive foliage, bark and fruit. In 1904, a list of the genera of trees 

 and shrubs in the arboretum, with the number of species of each; and, in 1899, there 

 was published a catalogue of the trees and shrubs in the arboretum which had been 

 tested up to that date, with notes regarding hardiness. 



In the annual report for 1906 a list of thirty of the best hardy flowering shrubs 

 was given, with short descriptions. In the annual report for 1909 was published a 

 list of the best twenty-five hardy ornamental deciduous trees, a list of best twenty-five 

 hardy evergreens, and a list of the best lilacs, ..with short descriptions. A descriptive 

 list of the best philadelphus or mock orange appeared in the report for 1910. Finally, 

 in 1912, an article on ' Hardy Roses and their Culture ' was published in the annual 

 report and also in bulletin form. 



In 1911, Mr. F. E. Buck, B.S.A., was appointed to assist the writer in ornamental 

 gardening and, during the past three seasons, considerable experimental work has 

 been in progress which will be reported upon as rapidly as the material can be got into 

 order. Especial attention has been paid to annuals, and following is an article pre- 

 pared by Mr. Buck on ' Everlastings ' which will no doubt be read with much interest :—
