7 6ft. or 7 ft. high. In an 
# area of a house in Berke- 
ley Street, there were, in 
1836, two plants, about 
6 ft. high, and of propor- 
portionate bulk, Mr. 
Bowie, in avery interest- 
ing communication to 
the Gard. Mag.on raising 
Australian and Cape 
shrubs from seeds, and 
acclimatising them to 
Europe, proposes to place 
the Plectranthus fruti- 
cdsus in green-houses, 
as the most susceptible 
of cold; which, if pro- 
perly placed, will prove 
a warning thermometer 
to guard against direct 
injury to others, as it is 
always the first to suffer. 
and consequently will 
show the _ increasing 
harm. (Gard. Mag., vel.

Sideritis __ciéndicans 
Ait., Com. Hort., 2. t.

ra, an old inhabitant of 
; green-houses inEngland, 
: and of orangeries in 
eo France, where we have 
y BA seen it growing about 
T [a the same’ height as the 
Plectranthus fruticdsus, 
There are several other sorts, from the Canaries, Spain, the Levant, &c., which will be found enume- 
rated in the Hortus Britannicus, all of which would probably live on rockwork, with very little pro- 
tection during winter. 
Leonotis Leonnrus R. Br.; Phldmis Leonirus L., Bot. Mag., t. 478.5; is a Cape shrub, which has 
been in the country since 1712. It grows to the height of 3ft. or 4ft., and is tolerably hardy. It 
bears showy scarlet flowers, but does not flower freely in Britain. 
Sphdcele campanulita Benth., Bot. Reg., t. 1382, and our fig. 1151., is a 
shrub, from Chili, which grows to the height of @ ft. or 3 ft., and produces its 
pale blue flowers in July and August, There is a plant in the Horticultural 
Society’s Garden,,which has stood out at the foot of a wall since 1832. S. 
Lindléyi Benth., Bot. Reg., t. 1226., is another species which was introduced 
from Valparaiso in 1825.

ip " Dracocéphalum canariénse Com. Hort., 2. t. 41., is 
1150 W an old favourite, much esteemed for its fragrance. 
Spy Trained against a wall, and protected during winter, 
it will, in two years, cover a space 4 ft, or 5 ft. high, 
and 5ft. or 6 ft. broad; producing its pale purplish 
flowers in abundance from July to September. It 
may be raised from seeds early in spring, and turned 
out in the borders, like a tender annual. 
Salvia spléndens Ker, Bot. Reg., t. 687. ; S. formosa 
Willd., Bot. Mag., 375. ; S. fulgens Cav., Bot. Reg., 
1356. ; and S.Grahami Benth., Bot. Reg., t. 1370., and 
our fig.1151. ; are all splendid suffruticose plants, na- 
tives of South America, which will live through the 
winter against a wall, and flower beautifully during 
summer ; but, though technically shrubs, in prac- 
tice they are best treated as herbaceous plants, kept 
in pots and pits, or green-houses, through the winter, 
and turned out into the open borders in spring. 
S. Grahami has stood in our garden, in the open 
border, through the severe winter of 1835-36, without 
any protection whatever. S. chamcedrydides Cav. is 
a dwarf species, the flowers of which are of a pecu- 
liarly intense and brilliant blue. It is frequently grown in England for planting out in beds in regular 
flower-gardens, where its flowers form a mass of beautiful blue. There are some Cape species, which 
are truly ligneous, that might be tried against a wall. Of these, S. area is one of the most splendid. 
Prasium majus L., F1. Grec., t. 584., is a native of Spain, which has been in the country since the 
time of Gerard. It grows 3 ft. high, and produces its white-spotted flowers, some of which are’ fol- 
lowed by pulp-covered seeds, from June to August. 
Prostanthéra lasidnthos Lab., Bot. Reg., t. 143., is a native of New South Wales, which has stood 
a ne Horticultural Society’s Garden, at the foot of a wall, since 1831 ; but it was killed in the spring 
of 1836. 2 : 
Other half-hardy gee belonging to this order may be found in considerable numbers by looking 
over the lists in our Horivs Britannicus ; but, with the exception of the salvias, the phlomises, and 
the lavandulas, we can hardly recommend any of them for culture, except in the warmer situations 
of the south of England, where they will grow with little or no protection. Where much labour 
and expense are required to protect tender plants during winter, only those that are truly ligneous 
ought to be made choice of; but where the climate is such as to render protection easy, a greater 
latitude ie | be allowed,
