south-east exposure in good loam, leaf-mould and sand, with 
the addition of a little lime rubbish and broken sandstone; 
abundance of water during thei growing season is most essen¬ 
tial. 
Saxifraga, diapensioides is a. very beautiful species and veiy 
seldom seen in good condition. It produces tiny rosettes of 
oblong, grey leave®, beautiful white flowers, appearing in June. 
It delights in a moist, well-drained sunny position, wedged 
between, stones (limestone preferred) in a mixture of loam, 
sand and grit, with the addition of a little peat. 
Saxifraga poirophylla is; a rare) species from the South ot 
Europe, resembling in foliage the well-known burseriana, with 
beautiful red flowers. Plant at the bottom of the rockery, 
facin°' west, in, good sandy loam and limestone, well diained. 
Saxifraga aretioide® primulina; is a very diminutive but 
pretty variety, the flower-stalk, 1 in;, or so high, bearing beiau- 
tiful sulphur-coloured flowers, flourishing best on rockwork m 
very light sandy soil, in, a sunny but moist position. _ 
Saxifraga, Hirculus isi a, peculiar and pretty speicies. It, is 
found on some of the mountains of Britain in marshy place®. 
Flower-stem erect, 6 in. to 9 in: high, bearing a beautiful 
solitary yellow flower, spotted with orange. A fine plant, for 
the bog garden, or at, the foot of the rockery, in wet peat and 
sand ; "it- must have plenty of moisture during the growing 
season. 
Saxifraga diveirsifolia, a, lovely specie®, with beautiful yellow 
flowers v hi. to § in. in, diameter. To grow it, to perfection, it 
ouriit, to be planted at, the bottom of the rockery, facing north, 
where it,will be well shaded from the sun. It delights m 
moist, peaty loam, but must, have thorough drainage. 
Saxifraga Elizabethae is in the way of S. apiculata, but 
superior to that well-known variety. The flowers and foliage 
are deeper in, colour; it is a better grower, and does; not turn 
brown in. the foliage like S. apiculata,. It should have a, south¬ 
west exposure, and a mixture of very sandy loam and lime¬ 
stone. 
Saxifraga Fergusomii is a, new hybrid, said to be a, erosisi 
between, S. Rhei and S. atro,purpurea,. It has the same habit 
a,s S. Rhei, but the flower's are dark red. To see this variety 
in perfection, it should be planted on the north side of the 
rockery, in, a very shady position, where the sun, si rays will 
n,ot reach it,, or, if in, a sunny position, it, must, be shaded 
before the flowers open, otherwise the petals will fade to a, 
very pale pink.

Ipomoeas. 
l The o'enus, Ipomoea is’ an extensive one, containing asi it does' 
over 400 species. Like'most members of the order Convoivu- 
laceae, the species are mostly twining or creeping, stove, green¬ 
house, or hardy herbs. 
The, annual species are propagated by means of seeds, the 
evergreen or perennial species by cuttings or layer's', the latter 
method being most efficacious in the case of I. Horsfalliae. 
Ipomoea, rubro'-caerulea is onei of the 1 best and most showy of 
the stove species, and may be grown and flowered successfully 
in 6-in. pots—-a great recommendation with Ipcunoeiasi,. asi the 
majority of’them succeed best when, planted.out, or ini leny 
large pots. Three or four seeds should be sown in ->-iu. pots, 
and they should afterwards bei potted on into a, larger-sized 
pet, without disturbing the individual plants. They may bg 
trained to small stake® until ready for a position in the stove, 
where they form fine subjects for training up thei pillars or 
roof. Feedin.o- with soot water and weak manure water tends 
to, strengthen the plants considerably. The beautiful sky-blue 
flowers, 'which gradually fade away to a reddish-purple, make 
a grand show. 
T. Horsfalliae, a perennial stove species, ha,si a beautiful red 
flower, but is; not nearly so free-flowering as its variety Briggsi. 
The latter isi to be preferred for this reason. 
I. Quamoclit differs from most of the other Ipomoeas In 
having pinnate leaves. The flower is small, solitary, and deep 
red in colour. 
I. Hardingii is a beautiful perennial species which succeeds 
well grown in water in a, tropical tank. It may then be trained 
round the edge of the tank, thus showing the large delicate- 
coloured flowers to advantage. 
I. Bona-Nox is; a stovei annual, the large white flowers having 
thei disadvantage of only opening at night-time, from which 
peculiarity it gains its name: 
One could not, finish a talk about Ipomoea® without some 
reference to I. purpurea, the popular Convolvulus major, or 
“ Morning Glory ” of nurserymen. This species, however, is 
too well known to need any description. In conclusion, I 
would say that Ipomoeas are of easy culture and well repay 
any trouble spent on them. The flowers, of course, last only 
a, very short time, but this in, my opinion is counterbalanced 
by the profusion in which they arei produced. F. M. 
Clerodendron fallax. 
Well-grown plants of this useful and showy subject art 
always much admired during the autumn, and to ensure a 
supply seed may be sown any time during February or March 
in well-drained 6-in. pots. Fill the pots half full of clean 
crocks, over which place; some rough pieces of turf, and then 
till to within in. of the rim with light, sandy soil. It is a 
good plan to, soak the seeds before sowing, a® they are veiy 
hard. Sow them thinly, and cover over lightly with some fine 
soil, and water in, carefully. Place the pots in a warm pro¬ 
pagating frame, where they can obtain a nice bottom heat, and 
cover over with paper until they are germinated. When the 
seedlings are large enough to handle prick them out into' small 
60-sizei pots, using a, light compost of loam, leaf-soil and sand 
passed through the 4-in. sieve. Shade the plants for’ a day or 
so, if the weather bei at all bright, and lightly syringe them 
over morning and afternoon. They will soon make plenty of 
roots, and before they become potbound give them another 
shift, into small 48-size pots, using the soil rougher than before, 
and leaving enough room to water thoroughly. A temperature 
of 65 deig. to 70 deg. will suit, them at this period, as if 
grown in too much heat the- flowers do not come such a good 
colour. Six-inch pots will be found large enough for the final 
potting, using a, soil composed of good turfy loam, picked by 
the hand, two parts, one part, peat, and one part, leaf-soil, 
with a good sprinkling of sand and 4-in. charcoal. The pots 
should be crocked carefully, and some rough turf that will 
allow the water to pass through easily placed over them. Pot 
rather firmly, and sprinkle some sand on the top to give it a 
neat and finished appearance. Shade as before for a time 
until they become established, and keep the syringe going 
during hot weather. When the pots become full of roots a 
watering of weak manure water or some good fertiliser about 
twice a, week will greatly help in building up fine blooms. 
The plant is. of rather a spreading habit, and on this account, 
should be given plenty of room. When, the flower-spikes show 
signs of pushing up discontinue the syringe overhead, but 
keep the pots and stage well damped. When the flowers are 
opening remove the plants to a, cool house or conservatory, 
and discontinue the use of stimulant®', or they will not last so 
long in bloom. If it is thought desirable to- save the seed, 
place the plants in a cool frame or house and gradually with¬ 
hold water as the flower-sp'ike-s show signs of withering, or, I 
should say, ripening. As soon as they are thought to- be ripe 
enough cut them off and place in a shallow box and put, on 
the shelf in full sunlight, till the seed drops out, when it may 
be ga,there,d up and placed away in a dry position ready for 
sowing the next year. 
Clerodendron fallax may also be propagated by cuttings, 
placing the old plants in peat in. the early spring and syringing 
to induce them to grow, hut the plants are best if grown from 
seed every year, and produce much finer flowers than where 
cuttings are used for propagation. R. Thatcher.
