ORNAMENTAL SHRUBS, VINES, AND HEDGE PLANTS. 203 



largely planted. It produces long, slender branches that 

 in the spring are covered with beautiful white double 

 flowers. These branches may be bent around so as to form 

 a very perfect wreath, whence the name. It has the habit 

 of producing very few lateral branches, so that severe prun- 

 ing should be given to a few of the strongest canes after 

 blooming in the spring. Never prune the spiraeas in the 

 spring before blooming if an abundance of flowers is 

 desired. Like all the other species of this genus, the flowers 

 last but a short time. 



LOBKD-I.KAVED SPIRAEA (S. trilobata). A d\tarf, com- 

 pact grower, producing large masses of white flowers. 



BUMALD'S SPIR^JA (S. Japonica, var. Bumaldd). A 

 dwarf -growing shrub, with large quantities of rose-colored 

 flowers. 



THUNBERG'S SPIR^A (S. Thunlergii). The most 

 graceful and beautiful of the spiraea while young. The 

 foliage is fine and fern-like, and changes to a beautiful 

 golden-orange color late in the autumn. It needs cutting 

 back severely to cause the lower branches to grow with 

 vigor. 



VAN HOUTT'S SPIRAEA (S. Van Houttii), Fig. 109. The 

 finest of all the spiraeas. It is dwarf in habit, with grace- 

 ful pendulous branches that, when in bloom, are weighted 

 down with pure white blossoms. The flowers are of very- 

 short duration, but the foliage is good. 



WATERER'S SPIR^A (S. Jap., var. "Anthony Waterer "). 

 Resembling the Bumalda, but with the most beautiful, 

 large clusters of pink flowers, and continues to bloom, 

 throughout the summer more or less if the clusters are cut 

 off before the seed-vessels mature. 



SNOWBERRY-SHRUB (Symphoricarpus racemosus). A
