IXTA. 
ria, the Woad, is a British plant, 
260 
used for dyeing blue, and which | 
looks well in a miscellaneous border | 
er shrubbery. Some of the species 
are dwarf plants, very suitable for 
rockwork. 
Isoro‘con.—Protedcee.—Austra- 
lian plants, with very curious leaves | 
and flowers, nearly allied to Banksia. 
They should be grown in peat and 
sand, mixed with a little turfy loam, 
and the pot should be a third filled | 
with potsherds broken small. These | 
plants are very difficult to cullivate, 
as they are very apt to damp off; 
the cuttings also are extremely 
difficult to strike. 
Iso’roma.— Lobeliicee.— Annual 
and biennial plants, which may be 
/ sown in the open ground, or brought 
4 
forward in a hotbed, and planted 
out in May. J. avxilléris is a most 
beautiful and elegant plant, the 
flowers of which look like a large 
lilach jasmine. 
I'vea.——EHricécee.—A litile hardy 
American shrub, which requires 
peat soil in British gardens. 
Tvy.—See He’pera. 
I’x1a. — friddcee. — Bulbous- 
rooted plants, with very beautiful 
flowers, which vary exceedingly 
in colour and form. They are all 
natives of the Cape of Good Hope, 
and they are generally grown in 
pots in greenhouses ; but as, when 
thus treated, their slender stems are 
apt to become etiolated, and conse- 
quently very weak, they do much 
better in the open garden, treated in 
the following manner, in the climate 
of London :—A bed of any width 
and breadth that may be required, 
should be dug out to the depth of 
two or three feet, according to the 
nature of the sail, a retentive clay 
requiring to be dug deepest. This 
bed should have a third part of its 
depth filled with pebbles, brick- ae 
or any other draining material.

of rotten cow-dung, so as to fill the 
bed to within about a quarter of its 
depth from the surface ef the ground. 
The bed should then be filled with 
a mixture of light turfy loam and 
sand, the loam being broken or 
chopped small, but not sifted. The 
surface of the bed should be raised 
two or three inches above the level 
of the surrounding border; and it is 
most desirably situated, if backed 
by a south wall, and sloping from 
the wall to the gravel-walk. In this 
bed the Ixia roots should be planted 
in quincunx ; and if they are pro- 
tected by a thatched covering raise 
on 2 slight wooden frame duri 
winter, they may be left in 
ground several years without sus- 
taining any injury. In the north of 
England, or in any cold wet climate, 
the Ixias may be planted in October 
in pots, well drained, with a layer 
of cow-dung over the drainage, and 
filled up with a mixture of turfy 
loam and sand. The Ixias should 
be planted three in each pot; and 
the pots should be plunged into a 
hotbed, and covered with a glass 
frame during winter. In spring, the 
glasses may be gradually removed, 
and when the flowers are nearly 
ready to expand, the pots may be 
removed to the greenhouse, or the 
window of a sitting room. Where 
the soil of a garden is a fat yellow 
loam, or a chalky or other porous 
subsoil, and the situation dry and 
yet sheltered, the bulbs may fre- 
quently be planted in the open 
ground, and left there for years, 
without any other care than cover- 
ing them with a heap of dead leaves — 
during winter. ,

stove plants. The history 0 fi 
the genus, is rather curious. TI
