AMONG THE ALPINE 
FLOWERS. 
“ O come at la5t, to whom the spring.tide’s 
hope 
Looked for througrh blossoms, what has thou 
for me’^ ” 
Where suitable glass accommcKlation is 
available few plants give more satisfaction 
to the cultivator than roses. But to grow 
them with any large measure of success 
houses must be specially devoted to them. 
A mistake which is often made by the in¬ 
experienced is that of growing too many 
varieties. It is a much better plan to 
grow three or four well-tried sorts, choos¬ 
ing the colours which are most desirable for 
decorative purposes. 
To be successful with early forcing the 
roses must be well established in their pots, 
and the w^ood. be tlioroughly ripened 
before placing them in the forcing house. 
Such plants should now be in an exposed 
situation outdoors, where they must remain 
until the time comes for placing them in¬ 
doors. This time will, of course, be 
governed by the date at which flow’ers are 
required. Before placing them indoors re¬ 
move a little of the surface soil, and top- 
dress with loam, old lime inibble, and bone- 
meal. In most private establishments no 
attempt is made to force roses till early 
spring, when the chances of failure are 
few, provided their cultural requirements 
are well attended to. 
Pruning pot roses required for very early 
forcing should not be done until the wood 
is quite ripe; the growi>hs should then be 
cut back to three or four eyes. An impor¬ 
tant point to remember when the roses are 
in active grow’th is to remove all the less 
promising shoots, and especially those 
which are growing in the centre of the 
plants. Very little pruning will then be 
required beyond the shortening back of the 
young wood. 
Air must be very carefully admitted at 
all times, and unless the conditions out¬ 
doors are very favourable the top ventila¬ 
tors only should be used. Mildew is one of 
the worst enemies, and the grower will be 
wise to anticipate an attack of this trou¬ 
blesome pest by using flowers of sulphur 
freely about the house, especially near the 
hoWater pipes. Grubs also must be 
sought after, and picked off by hand when 
found. A mild fumigating with a nicotine 
compound will keep the plants free from 
aphis. During fine weather the foliage 
Biust be syringed with rain watei*, the tem¬ 
perature of which must not be lower than 
that of the house. During the early stages 
of growth water must be given with great 
care; later on, when growth and roots are 
more active, it may be given more liber¬ 
ally, and when the flower buds are forming 
stimulants must be given. Diluted liquid 
farmyard manure, sootwater, and guano 
may be given alternately. 
After flowering the requirements of pot 
rcses must be attended to just as assi¬ 
duously as before, for it is then that the 
flowering Avood for another season is de¬ 
veloped. Those which liaA^e been forced 
early should be repotted in spring or early 
summer, and plunged outdoors, removing 
a 1 flower buds as they appear. The later 
P ants need not be potted until the autumn, 
lants for late spring blooming may be 
^ and potted now, plunging the pots 
J' Ihe rims. Should very severe 
set in the roots must be covered 
ith short litter, and some dry material be 
plac^ OA^r the heads. 
he climbing roses need similar treat- 
to^th hybrids in regard 
heir general cultural requirements. In 
this case the pruning consists chiefly in 
shortening hard back tAvo or three of the 
Aveakest shoots to encourage str<vng growths 
from the base. After flowering the old 
flowering Avood must l>e cut out to make 
room for the young shoots. At this stage 
the plants must be repotted, and plunged 
oukloors. 
Pot roses of great merit are noAv fairly 
numerous, but a rigid sele<tion has to be 
made in most places. Among H.P. s the

Zauschneria. californica. 
Perched on a prominent terrace stands 
the brilliant Californian zauschneria, or 
the “ humming bird s trumpet,” as it is 
popularly called. A A^ery precious floAver it 
is indeed, as it Avaves in the autumn winds, 
and cheers us as Ave pass it by or linger 
to look at its bright scarlet, trumpet¬ 
shaped blooms. It is a true treasure, Avhich 
all should oAvii Avhere they can give it 
plenty of sun, and the light, dry, stony 
soil it seems to love. Of the various forms 
in cultivation one should be eschewed by 
all, save those in the Avarmer parts. This, 
which has hairy or pubescent leaA^es and 
brandies, seldom comes into bloom 
timeously. The one here is different, and
