Spiraea The Spireas 



A large group of showy free-flowering shrubs of inestimable garden 

 value. Among the species may be found those that produce a profusion 

 of flowers in earliest spring, others that blossom at later intervals, and 

 even varieties that continue to produce flowers from midsummer until 

 autumn. In general, they are graceful, compact bushes, many of them of 

 great hardiness. They thrive best in moist, fertile soils, preferring sunny 

 exposures. For convenience, the varieties are arranged in two groups, 

 early- and late-flowering.

 shrub of garden origin. Leaves narrow, bright green, fading with tones of yel-
