CLEMATIS JACKMANNI ALBA. 
[Plate 605.] 
ITN 1877, we published in The Clematis as a 
(1 Garden Flower, the following descrip- 
^ tion of this variety, which had been 
raised by Mr. C. Noble, of Bagshot, and 
had been exhibited by him in the shape of cut 
specimens at one of the meetings of the Royal 
Horticultural Society :— 
“ A light-coloured variety, apparently belong¬ 
ing to the early Jackmanni group, and raised 
from C. Jackmanni crossed by C. Fortunei. 
It is of vigorous growing habit, the leaves 
pinnately divided with ovate lanceolate leaf¬ 
lets, or ternate with the terminal leaflets some¬ 
times lobed. The flowers are four to six- 
sepaled, of a greyish white, the sepals elliptic- 
oblong acuminate, the fllaments short, white, 
with whitish-brown anthers. It is the nearest 
approach yet made to that great desideratum, 
a white-flowered Clematis JackmanniF 
From that time till the past summer little or 
nothing was heard of C. Jackmanni alba. 
Some fatality seems to have attended it, and 
prevented its oft-expected reappearance in 
public; in fact, we beheve, it was at one time 
nearly lost, but it has at last revived, and on 
July 24 Mr. Noble produced at South Ken¬ 
sington a handsomely grown and well-flowered 
specimen, which received the unanimous award 
of a first-class Certificate, and well deserved 
such a mark of distinction. Our figure, drawn 
by Mr. Fitch, shows sufficiently well its pecu¬ 
liar characters. Like true Jackmanni it has 
pinnated (not ternate) foliage, and like, that 
variety too, it bears on the current year’s 
shoots masses of flowers, which are also like 
it variable as to the number of sepals, some 
flowers having six, -and others only five, or 
four. Again, as in that splendid hybrid, as 
soon as the earlier flowers die off they are 
replaced by clusters of buds which spring up 
to succeed them, by which means the con¬ 
tinuous succession of blossoms characteristic 
of the group is assured. The colour effect 
of the flowers is white, but on close inspection 
they are found to be just tinged with blue, 
which gives them the faintest possible flush of 
grey. We hope it may prove to be as hardy 
and vigorous a grower as C. Jackmanni itself, 
which for its hardiness, vigour of growth, and 
freedom of flowering stands at the head of 
shrubby climbers for the outdoor garden. 
In a fine illustrated work on these larger 
flowered Clematises recently published, M. 
Lavallee has asserted that C. Jackmanni is not 
Jackmanni—that is to say, it is not a hybrid, 
as stated by the raiser Mr. Gr. Jackman, but a 
species (^hakonensis) first introduced from 
Japan, and then according to this theory 
claimed as an English seedling. We are bold 
to assert on the contrary that C. Jackmanni 
is Jackmanni and nothing else, a veritable 
hybrid of which the origin and whole history 
is well known to many of us, and which was 
raised nearly twenty years before C. hakonensis 
was described. The characteristics assigned 
to C. hakonensis, moreover, do not tally with 
those of C. Jackmanni, since the former has 
the leaves “ ternate ” and the sepals “ scarcely 
an inch long,” whereas in the latter the leaves 
are pinnate, with five or more leaflets, and the 
sepals are at least two and a half inches long. 
It must therefore be concluded that M. 
Lavallee is altogether in a fog respecting the 
true C. Jackmanni. —T. Moore. 
TREE AND SHRUB PLANTING. 
S HE season is drawing near when such 
work as planting trees and shrubs is 
resumed. Few planters do the work 
^ during the winter months, except cir¬ 
cumstances compel them; autumn and spring 
are the periods which are preferred for exe¬ 
cuting the work, though during summer ever¬ 
greens are sometimes planted with much 
satisfaction. Early during last August we 
planted many yews, and they laid hold of the 
soil readily, and made some little growth 
before the autumn was past. During a period 
of more than twenty years we have seldom 
missed a season without planting large breadths 
of shrubs of every class, deciduous as well as 
evergreen, also forest trees in great variety ; 
and have found with evergreens that in early 
autumn (say during September) and late spring 
when growth was about to commence, the 
plants always did well. Deciduous plants 
always moved off satisfactorily into growth 
when planted just before the leaves began to 
fade, or when growth was commencing. 
When trees are put into soil like puddle.
