siliquastrum alba, the white European Judas tree, is 
not hardy at the north. 
21. — The rosaceous group contains a large number 
of species which together produce the most brilliant 
spring flowering effect of any woody plants in north- 
ern regions, surpassing even the Rliododendrons., 
which appear later. Take Primus in its peach, 
apricot, plum, cherry and bird-cherry sections, and 
it is difficult to imagine greater brilliancy of blossom 
than may be collected together by a good selection of 
the trees and shrubs it contains. The pink, white and 
weeping almonds, how early and brilliant are they. 
Then P. Davidiana, P. nana, in three or four varieties, 
P. Persica, the double flowering peaches, with pink, 
white and magenta double flowering forms — the last 
perhaps the most exquisite in color of all spring 
flowering small trees. Then there is a curious form 
bearing flowers of all the coloi's — ^variabilis, I think it 
is called. There are red leaved and yellow leaved 
peaches to add to the effect — a little later. There are 
eight or ten apricots, including P. Mume and its 
varieties. Among the plums are as many well worth 
planting for their wealth of spring flowers. In the 
cherry section are some grand things, not forgetting 
the wild red or black cherry, for its ultimate size. P. 
avium fl. pi. is another that sometimes becomes a fine 
tree. P. cerasus, Rhexii fl. pi. is a double form of the 
same cherry ; P. Chamaecerasus pendula is often 
wrongly attributed to Japan ; P. Japonica fl. albo- 
pleno, and roseo-pleno are very charming double cher- 
ries which should always be planted ; P. pendula is 
the small flowered “rosebud” Japanese cherry. There

are also varieties of P. Pseudo-cerasus among these 
cherries well worth looking after, including one called 
SPIR,\EA CANTONENSIS 
fl. luteo-plena, which I have not yet seen. Some of 
the bird-cherries become large trees, the native “black 
cherrv,” P. serotina, being verv flne, with long racemes 
of white flowers late in spring. The European P. 
Padus has its racemes less drooping, but otherwise 
similar. P. Maacki is another of this type. 
Spircas are shrubs and a very excellent lot of white- 
flowered spring bloomers may be had from among 
them. S. Thunbergii, prunifolia, p. flore-pleno, Can- 
tonensis. Van Houttei, media and arguta being among 
the most useful. 
N eillia.^ are the nine-barks, N. opulifolia lutea being 
a good yellow-leaved form. 
Stcphanandra is another small genus, which has 
been separated from Spireas. S. flexuosa is a neat 
shrub, which in foliage and flower reminds one of 
hawthorns. 
Exochorda grandiflora is a fine white-flowered 
shrub, which attains to lo or 12 feet with age. 
Kcrria Japonica is an old favorite, with bright 
golden flowers, the double-flowered form being upon 
the whole the best, although the single is excellent. I 
care little for the variegated kinds. 
Rhodotypus Kerrioides is a white-flowered plant of 
somewhat similar character — the “white Kerria” of 
nurseries. 
Ruhas is the extensive blackberry and raspberry 
genus. A very large number are carried in the better 
botanic gardens, and spring flowering species, such as 
R. deliciosus may be employed. They are rather com- 
mon plants, however. 
Geuni triflorum and Potentilla rupestris are exam- 
ples of herbaceous plants belonging to the group. 
These and Fragraria Indica and the kind called Vick’s 
everbearing, may sometimies be usefully employed as 
covering plants for the bare soil of rose beds.
