60 TRANSACTIONS OF THE AMERICAN INSTITUTE. 



iutcrmediatc shades, the difforeiit varieties blooming from May 

 until frost. The foliage of the Reetjefiii is quite pretty, let alone 

 the clusters of snow-white flowers. They are all hardy, and easily 

 propagated by layers and suckers. They grow from four to eight 

 feet hio-h, and a l)ed of spiraeas, arranged in an oval form, with the 

 taller growing sorts in the center, diminishing in height to the 

 outer edge, makes an attractive collection of flowering shrubs. 



Syringa (Lilac) is one of the oldest shrubs, but will always be 

 a favorite on account of its early bloom and sweet perfume. The 

 old sorts are partially giving way to the more delicate Chinese 

 and Persian, which grow from four to six feet high, while the 

 common [S. vidgaris) reaches eight to twelve feet in height. They 

 bloom last of May and early in June, are very hardy, thriving 

 with ue£!;lect, and are often employed for screens to out-buildings. 



Thuja occidentalism 8iberica, etc., (Arber vitoe), though usually 

 classed among evergreen trees, they are so slow of growth, and 

 some of them so dwarfish in habit, we include them in this list. 

 The common American is much used for evergreen hedges, and is 

 also a o-ood plant or tree for single specimens, or for screens about 

 out-buildings, fruit-yards, etc. The Chinese is very pretty, but 

 not perfectly hardy. In the Siberian, however, we have a dwarf, 

 compact growth, perfectly hardy, and very desirable as single 

 plants near the dwelling to relieve the monotony of winter. The 

 aurea, or golden, is a beautiful, hardy plant. Set last of May or 

 early in June. 



, Viburnum opulus (Snow Ball). — A strong growing shrub, grow- 

 ing- from eight to fifteen feet high, and is an attractive object 

 when covered with its large " balls " of snow-white bloom in May 

 and June. It should not be crowded, as it is a rank grower, and 

 may be increased by cuttings or layers. 



Weigelia rosea is of comparatively recent introduction from 

 China, and well deserves a place even in small collections. It is a 

 profuse bloomer, flowers rose color, opening in May, is perfectly 

 hardy, and readily increased by cuttings, layers, or division of 

 roots. Set early in April, in any good garden soil. 



Climbing Plants. 



The flower garden is incomplete without some of those hardy 



perennial climl)ers. They should be planted near the house, in 



some situations in close contact, to be trained to the building, or 



what is better, to trellises, fitted up around the piazza and other
