HARDY WOODY PLANTS 179 



the killed portions it is possible to have fairly good plants at all times. From 

 the purely decorative jjoint of view this is one of the best of all the spireas. 



Spiraea vanhouttei. Vaxhoutte Spirea. One of the most popular and 

 widely used shrubs in the whole nursery catalog, and indeed one of the 

 I'est. Perfectly hardy and satisfactory. 



Stupluilea trifolia. Aimericax Bladderxut. A rather interesting small tree 

 or large shrub. Suitable for planting in woodland borders. 



Stephanandra flexuosa, Cutleaf Stephaxaxdra. A delicate and attractive 

 shrub of good form and texture. Very suitable for mass planting on the 

 lawn and in general park work. Its one defect is a tendency to kill back 

 at the tips of the branches during the winter. Nearly always the plants need 

 going over in early spring, cutting out these small dead portions. This de- 

 fect, however, is not very serious, and the plant is well worth the extra 

 trouble required. 



Si/mphoricarpos racemosus, Comjiox Sxowberry. An attractive small 

 shrub with graceful habit of growth. Its most pleasing feature consists of a 

 fine crop of ^^•axy white berries which persist far into the winter. Excellent 

 for foundation plantings and general use on small lawns. 



Si/mphoricarpos vuh/dris, Coralheurv. A hardy, solid, ratlier satisfactory 

 shrub of moderate height and medium texture. The bright red berries which 

 persist well into the winter are a feature. 



Syringa, Lilac. A considerable number of the hybrid lilacs have been 

 tested here and found generally ^ery satisfactory, much to be recommended 

 in preference to the wild, weedy, unselected varieties from the roadside. 



Si/r'uKja jdpotilcd, Japax'ese Tree Lilac. This Japanese species has long 

 been growing on the college campus, the older trees attaining a height of 

 twenty-five feet. The flowers are borne late in the season in very large showy 

 clusters, the odor being unfortunately unpleasant. Still this is an ornamental 

 tree worth using in many collections. 



Si/ritii/a pekiiiensis. Pekixc; Lilac. A good, iiardy species, worth a place 

 in the shrubbery collection. Later in its blossoming period than the more 

 common species. 



Si/rinc/a persica, Persiax Lilac. A fine, strong plant with fragrant flowers 

 smaller than the conunon lilacs. Well known and always to be reconunended. 



Syriiif/a villosa. Late Lilac A strong, hardy shrub of rather upright 

 growth. Flowers freely considerably later than the ordinary lilac. Unfor- 

 tunately the blossoms are not fragrant, or at least not agreeably so. Other- 

 wise this shrub is well worth general use. 



Syringa vulgaris, Commok Lilac. Various forms of the common lilac have 

 always been growing on the college grounds. These are hardy and thorough- 

 ly satisfactory, not even being troubled by the mildew, or at least not fre- 

 quently. They are excellent for mass planting in borders, etc., but for fine 

 ornamental effects they should be replaced with the better hybrid varieties. 



Tamarix odessana, Odessa Tamarix. A shrub A\ith tall, slim willowv 

 branches and feathery green foliage. Rather different and interesting. Xot 

 entirely hardy.
