228 PLANTING THE ORNAMENTAL GROUNDS 



Wild laurel, Kalmia latifolia. 



Erieaceous evergreen. Thekalmias and rhododendrons are among the 

 choicest of shrubs. They require a rather peaty soil and a somewhat 

 shaded situation, especially in winter (page 217). 



Rhododendron, Rhododendron Catawbiense, garden varieties. 



Sty rax, Sty rax Japonica. 



One of the most graceful of flowering shrubs. It may not be hardy 

 northward. 



Common snowball, Viburnum Opulus.* 



The cultivated sort is a native of the Old World, but the species grows 



wild in Michigan (known as High-bush Cranberry), and is worthy of 



cultivation. 

 Japanese snowball, V. plicatum (properly V. tomentosum) . 



Common lilac, Syringa vulgaris. 

 Josika lilac, S. Josikcea. 



Persian lilac, S. Persica. 



Various other lilacs are also hardy and desirable. 

 Mock -orange, Philadelphus coronarius and P. grandiftorus. 



Smoke-tree, Ehus Cotinus. 



One of the best shrubs for massing. Two colors are grown. 

 Dwarf sumac, E. copallina* 



Attractive in foliage, and especially conspicuous in autumn from the 

 brilliant red of its leaves. 



Sumac, smooth and hairy, E. glabra* and E. typliina.* 



Useful for the borders of large groups and belts. They may be cut 

 down every year and allowed to sprout (as in Fig. 157). The young tops 

 are handsomest. R. glabra is the finer species for this purpose. 



Three-lobed spirea, Spircea trilobata. 



One of the most showy early-flowering shrubs. Excellent for massing. 



Sorbus-leaved spirea, S. sorbifolia. 



Desirable for its late blooming, late June and early July. 



Plum -leaved spirea, S. prunifolia. 

 Fortune's spirea, S. Japonica, or S. callosa. 



Thunberg's spirea, S. Thunbergii. 



Neat and attractive in habit. Dwarf. 

 St. Peter's Wreath, S. hypericifolia.
