THE GARDENING WORLD.

Mr. Jones had a fine display during the last week of 
September. The variety under notice was raised by 
M. Sautel, and is almost sure to become popular for 
early flowering.

FORCING HARDY 
PLANTS. 
There are many hardy plants well adapted for 
forcing, and prove a valuable addition to the green- 
be abundantly supplied with water. Clumps may be 
potted on any time from November to Christmas for 
successional flowering, using a light loamy soil. 
After this operation has been performed they should 
be put away for a few weeks either in a cold frame 
or under a greenhouse stage, until the roots have 
commenced to grow ; they may then be brought into 
a warm temperature and forced as required, care 
being taken to give them plenty of water right on 
until the time of flowering. 
Deutzia gracilis is another of our hardy plants 
which forces easily, and when well grown is one of 
the prettiest of early spring bloomers, producing a 
profusion of its snow-white blossoms amid foliage of 
a delicate green. Like Spirasas, Deutzias when mak¬ 
ing their growth enjoy a liberal supply of water, but 
it is the treatment which the plants receive after 
flowering which determines another year's success. 
Too frequently they are turned out of doors and 
placed in some out of the way corner to give place

house and conservatory in fhe early months of the 
year, and together with a few pots of Ffyacinths, 
Tulips, Lily of the Valley, etc., form a charming 
spring display. Of hardy plants for this purpose 
none are more useful or in greater demand in their 
blooming season than Spirieas. Whether they are 
used simply for the decoration of the greenhouse, or 
for the adornment of windows, fables, etc., they are 
an acquisition : their spikes of bloom being set off to 
advantage by a wealth of bright green foliage which 
makes them even more attractive. 
Spir^as are very easily grown, and all they need is 
fi hbfise where they will obtain plenty of light and 
Spiraeas are such moisture-loving plants, and if 
possible the pots should be placed in saucers of 
water, which will considerably reduce the trouble in 
this direction. Spiraea japonjca is perhaps more 
largely grown than any other species as may be seen 
by a visit to any of our flower markets in spring. 
Spiraea palmata, though not nearly so much grown 
under glass, and does not force so readily as S. ja- 
ponica, makes a handsome plant, and this also 
requires plenty of moisture. Indeed, when we re¬ 
member that the old Meadow Sweet is allied to this 
family it is scarcely possible to err on the ride of 
catering, 
to other plants coming into bloom. This is decidedly 
wrong, as, if possible, they should be kept in the 
greenhouse, or failing this be transferred to a coo 
frame, and encouraged in growth, gradually harden¬ 
ing them until the end of May, when they may with 
safety be planted out of doors until they are required 
again for forcing in the autumn. Treated in this way 
they will bloom each spring, and make large specimens. 
Dielytra spectabilis, when brought on in a cool 
house, forms an attractive plant for a window. They 
should not be unduly forced, otherwise the flowers 
appear " washed out." Like the preceding plants 
Dielytras should be well supplied with water,
