half-hardy annual, bearing everlasting flowers. It
should receive the same treatment as Helichrysum. Blooms in May or
June. Height, 2 ft.

Helleborus (_Christmas Rose_).--As its name implies, the Hellebore
flowers about Christmas, and that without any protection whatever. The
foliage is evergreen, and of a dark colour. When the plant is once
established it produces flowers in great abundance. The plants of the
white-flowered variety should be protected with a hand-light when the
flower-buds appear, in order to preserve the blossoms pure and clean.
Any deeply-dug rich garden soil suits it, and it is most at home under
the shade of a tree. It prefers a sheltered situation, and during the
summer months a mulching of litter and an occasional watering will be
beneficial. Readily increased by division in spring or seed. Height, 1
ft.

Helonias Bullata.--A pretty herbaceous plant, bearing dense racemes of
purple-rose flowers from June to August. It grows best in peat, in a
moist position. It can be raised from seed or increased by division of
the roots. Height 1-1/2 ft.

Hemerocallis (_Day Lily_).--Old-fashioned plants of great merit.
Planted in large clumps they produce a grand effect. They are easily
grown in any common garden soil, and bloom in July. Height, 3 ft. H.
Kwanso has handsome, variegated foliage.

Hemp.--_See_ "Canna" _and_ "Cannabis."

Hepatica.--This enjoys a rather light, sandy soil and a shady
situation. The roots should be taken up and divided every second year.
Well adapted for surrounding beds or clumps of Rhododendrons. Flowers
in March. Height, 4 in.

Heracleum.--Coarse hardy biennials, that may be grown in any kind of
soil, and are readily raised from seed. They flower at midsummer.
Height, 2 ft. to 4 ft.

Herbs.--Thyme, Marjoram, Chervil, Basil, Burnet, Hyssop, Savory, etc.,
should be sown early in spring, in dry, mild weather, in narrow drills
about 1/2 in. deep and 8 or 9 in. apart, covered evenly with soil,
and transplanted when strong enough. Mint is quickly increased by
separating the roots in spring, and covering them with 1 in. of earth.
Sage is propagated by slips of the young shoots taken either in
spring or autumn. If planted in light soil and in a sunny position it
produces very fragrant flowers. Chives should be planted 6 or 8 in.
apart: they are increased by division in spring. Penny Royal, like
mint generally, will grow from very small pieces of the root; it needs
to be frequen
