HYOSCYAMUS. 
IZERIS. 
wants by its conspicuously drocping 
leaves, and reviving rapidly when 
water is given. It should be grown 
in a rich soil, and its branches 
should be cut in every year when 
it has done flowering ; as, otherwise, 
the branches are apt to become un- 
sightly from losing their leaves near 
the base. 
Blue Hydrangeas are very much 
admired, partly, perhaps, from the 
difficulty of obtaining them, for no 
plants can be more capricious. 
Sometimes they come without any 
trouble at all; sometimes applying 
any one of the numerous recipes re- 
commended will change the colour, 
either directly or gradually; and 
sometimes no care and no recipe 
has the slightest effect, and the 
flowers remain pink in spite of all 
that can be done to turn them blue. 
Water impregnated with alum, 
steel-filings, sheep’s dung, wood- 
ashes, peat-ashes, nitre, carbonate 
of soda, or common salt, are all re- 
commended, andall succeed—some- 
times. The flowers are sometimes 
turned blue by removing the plants 
to a loamy soil, and sometimes by 
planting them in peat. It is gene- 
rally allowed that the fine yellow 
loam found in some parts of Hamp- 
stead and Stanmore Heaths, and 
the peat of Wimbledon Common, 
are sure to produce the desired ef- 
fect ; asis also the peat of the bogs 
near Edinburgh, and that of the 
neighbourhood of Berlin and St. 
Petersburgh ; but these soils are not 
always to be procured when wanted. 
Water in which tan has been steep- 
ed is also very often successful ; 
though, like the other recipes, it 
cannot always be depended on. 
Hypro’cuaris.— Hydrocharidee. 
—Frogbit. A pretty little British 
water-plant, with white flowers.

Hyoscy‘amus. —Solandcee. — Hen- 
“ene. The annual kinds are quite 
hardy and will grow anywhere, but 
they prefer a soil that is rich and 
light. The English kinds are gen- 
erally found on old dunghills or 
heaps of mould from decayed vege- 
tables. ‘The perennials also prefer a 
light and rich, and yet deep soil; 
and they are increased by dividing 
the roots. 
Hyrve/ricum.—Hypericacee.— St. 
John’s Wort. The pretty yellow- 
flowered shrubs and _ herbaceous 
perennials known by this name at 
the present day, were formerly in 
high repute for driving away evil 
splits; and on this account were 
generally planted near dwelling- 
heuses. They were also highly 
valued for their medicinal properties, 
being believed te have a powerful 
effect in stopping blood and healing 
wounds. The most common kind, 
the Tutsan, or Park Leaves, is now 
made into another genus, under the 
name of Androsenum; but the 
botanical distinction is very trifling. 
All the kinds will thrive under the 
drip of trees ; and they will grow in 
| any soil and situation, though they 
prefer moisture and the shade. 
They are found in almost all the 
temperate climates of the world; 
|and they are propagated by sceds, 
and by dividing the roots. 
I. 
Ige\ris.—Crucifere.—Candytuft. 
Most of the kinds of Candytuft are 
well-known annuals, which received 
their name from J. umbelldta, the 
first species grown as a garden 
| flower, having been brought from 
Candia. The seeds should be sown 
in a rich light soil in autumn, 
where they are to remain, and kept 
rather dry during winter. They 
should be repeatedly thinned out, 
and in spring they should be water- 
ed with liquid manure, taking care 
| not to let the liquor touch the plants.
