SPIRAEA 



broadly oval, i| to 3^ ins. long, toothed towards the apex, more or less grey- 

 green and downy beneath, or sometimes green. Flowers bright purplish 



rose, crowded in 

 an erect, pyramidal 

 panicle terminat- 

 ing the shoots of 

 the year and 3 to 

 8 ins. high. It 

 blossoms in July 

 and August. 



This fine Spiraea 

 is found wild in 

 Western North 

 America, whence it 

 was introduced in 

 1838. Someauthors 

 regard it as a dis- 

 tinct species, some 

 as a variety of S. 

 Douglasii. Mr 

 Zabel considers it 

 to be a natural 

 hybrid between S. 

 Douglasii and S. 

 salicifolia, and 

 places under it, as 

 varieties, a series 

 of forms whose 

 leaves are more or 

 less intermediate 

 between those of S. 

 Douglasii (with a 

 grey-downy under- 

 surface), and those 

 of S. salicifolia 

 (with both surfaces 

 green and smooth). 

 All the forms of S. 

 Menziesii should 

 be pruned back 

 nearly to the pre- 

 vious year's wood 

 every spring, and 

 old worn-out stems 

 removed. 



Var. ANGUSTI- 

 FOLIA, Zabel. 

 Leaves narrowly 

 oblong, more taper- 

 ing at the base than 

 at the apex, toothed
