3i6 Ornamental Shrubs. 



wide a spread. It can be grown in this way, or kept in 

 due limits as a somewhat straggling bush, as may be 

 desired. The branches are numerous and quite twiggy,

 very much resemble large, single roses, and are borne in 

 profusion at the ends of the branches, continuing in suc-

 and half a dozen of these sprays will help to add lightness 

 and grace to a vase of the highly-colored flowers which 

 usually prevail at this season." The plant is reasonably 

 hardy, and can be depended upon both in the North and 



South.

THE ancients knew the elm by this name, which is 

 now applied to a mere shrub because of a fancied 

 resemblance in the fruit. It belongs to an entirely 

 different order, Rutacece, and has little in common with 

 the majestic elm. It rarely rises to more than eight feet. 

 The pteleas make up a genus of six species, only one of 

 which has a place among ornamental shrubs. P. trifoliata, 

 known as the hop tree and also as swamp dogwood, is a 

 much-branched shrub with alternate leaves usually in 

 threes, pinnate, and with oblong or ovate leaflets. If the 

 foliage is bruised or crushed it exhales a rather unpleasant 

 odor. The flowers are greenish-yellow, and have a short
