—— 
/ 
He'sreris. — Crucifere. — The 
Garden Rocket. These flowers, 
*#though very common, are rarely 
grown, as they require a great 
deal of care to bring them to per- 
fection. They are all perennials ; 
and as soon as they have done 
flowering, they should be taken up, 
and transplanted into fresh and very 
rich soil, which must be of a light 
and friable nature. The best is, 
perhaps, that which has been used 
during the preceding summer for 
celery trenches. Thus treated, the 
double white and double purple 
varieties of Hésperis matrondlis will 
attain extraordmary size, and will 
flower splendidly. | 
Hisse’rtia. — Dillenidcee. — 
Trailing shrubs with large yellow 
flowers, natives of New Holland, | 
which require a greenhouse in Eng- 
land. They should be grown in a 
mixture of sandy loam and peat, 
and they are propagated by cuttings. 
Hisi'scus.— Malvdcee.— Showy 
plants with large handsome flowers. 
The hothouse species, which are 
mostly from China, require a strong 
moist heat. Hibiscus syriacus, the 
Althea friitex, [or Rose of Sharon, | 
is a hardy shrub, which will grow 
well in any common garden soil, 
and of which there are numerous 
splendid varieties, some of the best 
of which are those raised by Mr. 
Masters, of Canterbury. The Al- 
thea fritex is propagated by seeds 
or layers. Several of the different 
kinds of Hibiscus are marsh plants, 
which grow best in pots suspended 
in water from the side of a pond.— 
See WaTER-PLANTS. 
Hiera‘cium. — Composite. —The 
common Hawkweed. British plants 
with large yellow flowers, which 
will grow freely in any light rich 
soil. They are propagated by seed, 
or division of the roots. The name 
is said to be derived from the juice 
of these plants being formerly given 
to hawks, to clear and improve their , 
x 
sight ; and it is still used for bathing 
the eyes in ophthalmic disorders. 
Hir.—The fruit of the wild Rose. 
Hirrea'strum.—A genus now in- 
cluded in Amaryllis. 
Hirro/puasa. — Eleagndcee. — 
Sea Buckthorn. Handsome hardy 
shrubs, natives of North America, 
which will grow in any common 
soil, and are increased by layers. 
Hirpu'‘ris.—Halordgee.--Mare’s- 
tail. A British aquatic ; sometimes 
planted in ponds, &c., to hide their 
termination, aud to give the water 
the appearance of a natural stream. 
Hor.—There are. many different 
kinds of hoes; but they may be all 
reduced to two classes: the draw- 
hoes, which have broad blades, and 
are used for drawing up the earth 
io the roots of plants, being pulled 
to the operator; and the thrust or 
Dutch hoes, which are principally 
used for loosening the ground and 
destroying the weeds, and which 
the operator pushes from him. 
Horne is an operation used for 
loosening the earth, and destroying 
weeds, where both. digging and 
forking would be injurious to the 
roots of the plants forming the crop. 
It is also used to draw the earth up 
to those plants which send out 
numerous fibreus roots close to the 
surface of the greund. This last 
operation is called hoeing up, and 
it is generally practised with annual 
culinary crops. 
Houiy.—NSee tex. 
Ho.iyHock.—See ALTH#'‘A. 
Home‘r1a.—iridee.—A genus of . 
Cape bulbs, formerly included in 
Morea, and which may be grown 
in the open air, if protected by a 
hand-glass during severe frosts or 
heavy rains. The soil should be a 
sandy yellow lo.m ; and the plants 
are propagated by offsets, which 
should be taken off and replanted 
in September or October. 
Honesty.—See Luna'ria. 
Honey Dew is a clammy sub-
