delicate rose are the flowers of Spircca menziesii and its 

 varieties. These plants are delicate and should there- 

 fore only be planted in well protected places. 



Not over three feet in height with beautiful red flowers 

 which are open throughout the entire Summer is 

 Spircca bumalda. This bush grows vigorously and does 

 well in any garden soil. It can be used for borders or 

 for small hedges. The var. ''Anthony Waterer'' devel- 

 ops darker and larger flowers. If the flowers, when they 

 have bloomed, are regularly removed, then this species 

 develops new flowers and will continue to bloom far 

 into the Fall. The young foliage shows a beautiful spat- 

 tering of white and red. When it is desired to keep 

 this species small, it should be pruned even with the 

 ground in the Fall. Garden forms to be recommended 

 are, among others, Spircra syringiflora, having red flow- 

 ers and a dwarfed growth. Also Spiraa cocinna, whose 

 flowers are flesh colored. For borders and the moun- 

 tain garden Spircea bullata can be used. This shrub 



All Spiraeas flowering in the Spring should not be 

 |iruned excessively. It should be done after flowering so 

 that the strength of the plant is not wasted in seed for- 

 mation. When pruning euly the soft immature wood 



Spircra grandiflora (Exochordia grandilloru, Koralkozi/i} 



must be placed in a sunny spot where it will then develop 

 its red hemispherical flowers in rich profusion. 



Spiraa van Hoitttei is a medium sized bush which cov- 

 ers itself luxuriously with snow-white flowers. These 

 make their appearance at the end of May. This plant 

 can be used for both individual planting and for groups. 

 and it develops its full beauty under both conditions. 

 The flowers always make their appearance on last year's 

 twigs. Therefore, when pruning, care should be taken 

 that the young wood is not removed entirely. 



The smallest of all the Spiraeas is Spircca dcciiinbcns. 

 Its flowers are white and appear in June. This shrub 

 seldom exceeds one foot in height. Spircca trilobata 

 introduced from Asiatic mountains grows about two feet 

 in height. The flowers are tiny, white, appear in May, 

 and cover the twigs. From China comes Spircca callosa 

 with rose-colored flowers. This species, and its variety 

 alba, are low shrubs which can be successfully used for 

 borders or low hedges. The var. alba flowers for a long 

 period and is therefore very valuable. 



Spira'a pritnifolia 



should be removed. Those Spiraeas flowering later in 

 the season should be strongly pruned after the flowering 

 period. This should not be left for the Winter. Here 

 the tips of the shoots coming from the ground and the 

 tips of the lateral shoots from the old wood should be 



Sl>iraa chamccdry folia 



cut ofl'. All thin and much branched twigs must also 

 be removed.
