CLEMATIS HERACLE^FOLIA 
VAR. DAVIDIANA. 
This showy clematis belongs to a small 
group of late summer and autumn-flowering 
kinds, which are cliaracteritsed by a sub- 
shrubby habit, large, rather coarse, and 
usually three-parted leaves and small tubu¬ 
lar flowers of a 'bluish colour. Some 
botanists accept but one sipeoies, and in¬ 
clude the four or five named kinds as 
varieties of C. heraclesefolia, whilst others 
give three sorts &peoific rank. By the inter¬ 
crossing of the various kinds a number of 
hybrids have been raised, some of which 
are su{)erior to the parents in colour of 
flowers ajid floriferousness 
C. reraclesefolia and all its forms are 
similar, so far as habit is concerned, and 
all require similar treatment. Growing 
from 2 to 3 ft. in height, the upper half of 
growth being more vigorous and the flowers 
deeper coloured than is the case with either 
C. heraclesefolia, or its varieties Hookeri 
and Stans. The variety Lavellei is, how¬ 
ever, more floriferous, and brighter- 
coloured than Davidiana, and should always 
be selected when one form only is required. 
The various hybrids raised by the late 
M. Lemoine, of Nancy, are all showy, and 
include such kinds as Azur, with large 
panicles of clear blue flowers; Columbine, 
with very large, violet-coloured bloom<5; 
Hybrida, having compact trusses of large 
pale blue flowers; and Iris, wdth deep blue 
flowers, borne in great profusion. 
Although none of the kinds grow much 
more than three feet in height in the open 
ground, they may be grown considerably 
taller against a fence or wall, providing 
care be taken in the pruning to prune no 
lower than the highest w ell-tieveloped bud. 
SALPIGLOSSIS. 
A bed of these plants, when in full flower, 
forms one of -the most beautiful features 
in a garden from the early ipart of July to 
the middle of September. Experienced 
cultaivatoLrs know well how to raise strong 
examples that will prove satisfactory, but 
the inexperienced may fail to grow good 
plants. Although they are not diflScult to 
manage, much care is necessary if the best 
results are to be secured. 
Alany ibatches of plants are spoiled when 
they are in tlie seedling ista^ge. If allowed 
to renuain in an over^roiwdod state too 
long, or not transplanted while very small, 
even w hen they have ample space to groiw 
in, the iplhints soon begin to flower and the 
stems harden. Afterwards, it is a diflS- 
cult matter to get them to grow freely, 
branch out, and bear large finely-coloured 
flowers.

Giant Groundsels.— -Among what 
may be regarded as giant membeiTs of the 
great Groundsel family must be included 
the (two Mexican species—Senecio grandi- 
folius and Senecio Petasites, both of which 
bloom during winter and early spring. Al¬ 
most a tree in. stature, although it will 
flower freely when but a few feet in height, 
S. grrandifolius has large, coarsely-toothed 
leaves, and massive, densely-packed heads of 
yellow flowers. Senecio Petasites is less 
sturdy in growth, and the flowers are dis¬ 
posed iu a loose, terminal panicle. The 
leaves, to>o, are lobed, hence it has been 
given the specific name of S. platanifolius, 
while S. grandifolius is also known as S. 
G h iesbr egh ti.—W. 
The seeds should ibe sown thinly in pots 
OT pans not 1 -ater than the middle of March. 
If placed in a warm atrTiotiire the seed- 
iliings will! sooui appear, and, in due course, 
they must be pricked out in boxes 4 in. 
deep. The next move must be to a bed 
in a cool frame. A fair quantity of sweet 
leaf-so-il and welLrobted manure should be 
passed through lan incih-mesh sieve, and 
added to the loam in the frame. Use 
coarse eiand witih the compost, but also put 
some on the surface of the bed. 
Slugs are very fond of these plants, and 
must Ibe guarded against, as they will soon 
destroy tiny specimens. It is importiaiit 
that they be grown sturdily and trans¬ 
planted wdth good balls of soil adhering to 
the roots. 
A somewhat Sheltered Ibarder, with a 
bachgiroimd of shrubs, Ibut open to the sun 
and very light, is an ideal position for 
salpiglossis to blossom in.
