SNOWBALL, Japan (TV- 
burnum plimtum). This va- 
riety is a valuable addition to 
the list of hardy shrubs and 
surpasses the common Snow- 
ball in many respects. We 
can recommend this with a 
certainty that it vill please. 
It forms an erect, comi)act 
bush 4-6 f«et high, and blo.s- 
soms early in .June, when the 
plants are covered from the 
ground to the toi)S of the 
branches with balls of flowers 
as white as snow, clustered 
one against the other in dense 
masses. Leaves are of a 
bright green, with a beauti- 
ful plicated or jilaited sur- 
face.

mental Trees.]

period of the .Spiraeas ex- 
tends from spring to late 
summer, some of them flow- 
ering at a time when there 
is but little in bloom. 
SPIR/EAS, Aurea or 
Goldzn (Opulifolia aurim). A 
striking variety of decided 
beauty, and one of the most 
effective shrubs for a lawn. 
Foliage green, bordered with 
a rich, golden yellow ; very distinct ar d beau- 
tiful. In June the branches are covered with 
a double white flower. 
SPIR/EAS. Callosa alba. A dwarf variety 
of the above, having jiure white flowers in the 
greatest profusion. Very desirable on account 
of its <Iwarf habit and free-flowering. 
SPIR/EAS. Prunifolla. (Bridal Wreath). 
One of the oldest and most hardy of the Spiraias. 
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 perfect wreath, whence the name. 
It has the habit of producing very few lateral 
branches, so that severe pruning should be given 
to a few of the strongest canes after blooming 
in the spring. 
SPIR/EAS Van Houtte {Van Houttei). Sur- 
passing all other Spirisas in the s'uperb beauty 
and gracefulness of its blo.ssoms. The plant is 
dwarf in habit,with graceful, pendulous branches

down with pure white blossoms, the plant being 
covered with a mass of flowers.

phns). Of vigorous habit ; very hardy, with
