The familiar Snowball of deligrhtfnl meiviory «eems to 

 be doomed. It is too much trouble to try t<> keep olf the 

 aphids. Fortunately its place can be taken by a Japa- 

 nese species that is even more satisfactory. Fig. 26G8. 

 The berries of the Japanese species, I". to)nentosH)n, are 

 a brilliant soarlet, changing to black. The foliage of this 

 Snowball is also remarkably beautiful. The leaves are 

 olive-green with brownish purple or bronzy margins, 

 and their plicate character makes them very distinct 

 and attractive. The bush is entirely free from insect 

 pests. The single and double forms of the Japanese 

 species differ in the same way that is shown in Figs. 

 2n64: and 26GG. Unfortunately they have been confused 

 in many nurseries, and only the trained eye can tell 

 them apart in the nursery row. The double or Snow- 

 ball type is, of course, the one destined to the greater 

 popularity, though the single form is a shrub of great 

 value, especially for large estates and parks. The dou- 

 ble form is known to nurseries as I'il'iirinnii plicatuin, 

 hut its proper name is V. tomenfosii}it, var. pJivahim. 

 While it is hardy in New England, it is not a shrub that 

 can be transplanted as easily as many other species. 

 Hence it should be transplanted every second yaoj: in 

 the nursery until it is sold. The double form may be 

 propagated by cuttings of half-ripened wood in close 

 frames, or by laj'ers, which in some soils would better 

 remain two years. French nurserymen propagate it by 

 layering. The layers seem to suffer from winter and, 

 to be on the safe side, it is best to cover them well with 

 moss or leaves when the ground is somewhat frozen, so 

 that the frost may be kept in until spring. The clusters 

 are about as big as oranges and pure white. They are 

 in great demand for Decoration Day in New York. 



The single form, unlike the double, is easily trans- 

 planted. It is also readily propagated by layers or cut- 

 tings. Both kinds are hardy in the North and make 

 compact bushes G-8 ft. high.
