American. These “sea 
rockets” are rarely seen 
in gardens as they are 
difficult to grow away 
from the sea beaches. 
The British C. mariti- 
ma is pretty. 
Cleoine has ninety 
species distributed over 
the temperate regions. 
They are mostly annu- 
als, but a few are shrub- 
CLEOME SPINOSA. by. C. I'osea, C. speci- 
ossissima and a few others are in cultivation. C. 
pungens is found wild in places along the lower 
Delaware. These and many other plants of like 
character should be grown in masses. Two or three 
flowers on a single plant are not sufficiently effect- 
ive, except in small gardens. 
Reseda has thirty species mostly from the regions 
of the Mediterranean. There are larger, growing 
yellowish and white species sometimes seen in gar- 
dens, but none have the popularity of the odorous 
though dull colored mignonette. 
Cistus has twenty-five species mostly from Med- 
iterranean regions. They bear a host of names. C. 
laurifolius is perhaps the hardiest, and has some- 
times stood the winters of Philadelphia. They 
should be tried along the coasts further south as 
they are maritime in their preferences. They are 
summer flowering and fugitive but quite pretty. 
Heliantliemnin is a trifle more extensive as to 
species having perhaps thirty-five, and far more 
names. They are found all over the world in shrub- 
by and annual varieties. They are pretty little 
things, these Rock-roses, with their yellow or white 
spotted fugitive flowers. There are several species 
native to both Britain and America. They prefer 
gravelly or sandy soils. 
Viola, “violets” and “pansies” have 150 spe- 
cies scattered over the earth, mostly in temperate re- 
gions. They are so popular and well known that they 
need but little said about them. The sweet garden 
varieties are derived from Viola odorata, “violets,” 
and from Viola-tricolor, “heartsease,” with V. lutea, 
“yellow heartsease” which are the originals of the 
splendid race of garden pansies. We have 
a great many handsome native species and V. 
pedata, “bird-foot-violet” and its varieties are cer- 
tainly worthy of more attention than they receive, 
both from the spring-gardener and the hybridist. 
It is not too much to say that the coloring of this 
species is as rich as any in the genus. 
Idesia, is an arborescent wanderer from the 
tropical representatives of the parietal alliance. It 
is a monotypic tree from Japan with large leaves. 
It will probably be largely confined to the south, 
at any rate young plants have seemed somewhat 
tender at Philadelphia. 
Street Trees. 
The somewhat exaggerated desire on the part 
of local authorities for planting street trees — a most 
desirable act in broad streets and where there are 
no forecourt gardens — is likely to seriously injure 
trees of very pleasing character previously planted 
privately in gardens, and in that way to shut out or 
destroy one of the most pleasing of suburban as- 
pects. Street trees must of necessity be of one 
kind, and in that respect many of them soon be- 
come very monotonous; then they will grow large 
in time, let the kind be what it may. To check 
that evil it is necessary later to use the saw and the 
knife largely, and thus these trees must ultimately 
either be converted into mop-heads, be kept unduly 
thin, or be allowed to grow too large, and in that 
way not only shut out from the adjoining houses 
needful light and air, but also so much from the 
forecourt gardens, that these are robbed of all 
charm, and trees, shrubs and flowers become drawn 
and useless. On the other hand, a surburban street 
or road in which there are on either side forecourts 
of some 20 feet in depth usually have some few 
trees planted in them. It is in this case that variety 
exhibits so much that is pleasing, although that sat- 
isfaction is modified when here and there some fool- 
ish or thoughtless person plants American Oaks, 
Sycamores, Planes, Plorse Chestnuts or similar 
large trees that outgroAv space and everything else 
in the most unpleasant fashion. Perhaps it would 
seem an undue interference with personal liberty, 
but as we endure much in that direction for the gen- 
eral good now, it might be as well to grant local 
authorities some power to control tree-planting 
within 20 feet of the street or road, so as to check 
the putting in of any kinds that made growth far 
beyond the needs of the case. Equally, on the 
other hand, it would be well did such local author- 
ity offer every encouragement to the planting of 
suitable trees in these forecourt gardens. What 
wondrous beauty will flowering trees give to subur- 
ban streets in the spring and summer. Most of 
these also are of moderate growth, needing little 
pruning, and if some be given, in no case producing 
distorted heads. There are Almonds, double-flow- 
ering Peaches, Cherries and Thorns, Laburnums, 
Lilacs grown as trees. Crabs, or Pyruses of diverse 
varieties. Mountain Ash for berries and Sumachs 
for foliage, all most beautiful, though in a street no 
one wishes to see every tree a flowering one. A. D.
