ooms about May. The _Alba_, or white, variety is
also sweet-scented.

Hyacinthus--_continued_.

_CANDICANS_ (_Galtonia_).--The white Cape Hyacinth, or Spire Lily.
A hardy, summer-flowering, bulbous plant 3 ft. to 4 ft. in height,
gracefully surmounted with from twenty to fifty pendent, bell-shaped
snow-white flowers. Thrives in any position and equally suitable for
indoor or outdoor decoration.

_MOSCHATUS_ (_Musk Hyacinth_).--Bears very fragrant purplish flowers.

_PLVMOSUM_ (_Feather Hyacinth_).--A fine, hardy, dwarf plant suitable
for any soil. Its massive sprays of fine blue flowers, arranged in
curious clusters, 5 to 6 in. in length, resemble much-branched slender
coral.

_RACEMOSUM_ (_Starch Hyacinth_).--Rich dark-blue or reddish-purple
flowers. Very free-flowering and fine for massing. It is similar to
the Cape Hyacinth, but flowers in denser spikes.

Hydrangea.--This shrub delights in a moist, sheltered position and
rich soil. It may be increased at any time from cuttings of the young
side-shoots, 2 or 3 in. long, under glass, in sandy soil. The old
stems will also strike if planted in a sheltered situation. The plants
should be cut back when they have done flowering, and protected from
frost; or they may be cut down to the root and covered with manure.
They are well suited for the front of shrubberies, and also make fine
plants for pot cultivation. The flowers are produced in June and July.
Height, 3 ft.

Hymenanthera Crassifolia.--Ornamental evergreen shrubs, thriving best
in a compost of loam and peat. They are increased by cuttings planted
in sand and subjected to a little heat. Height, 6 ft.

Hymenoxys.--Pretty little hardy annuals that may be easily raised
from seed sown early in March in any garden soil. They bloom in June.
Height, 1 ft.

Hypericum (_St. John's Wort_).--Favourite dwarf shrubs. Any soil suits
the hardy kinds, but they prefer shade and moisture. These may be
increased by seed or division. The greenhouse varieties thrive best in
a mixture of loam and peat. Young cuttings placed in sand under glass
will strike. July is their flowering season. Height, 1-1/2 ft. to 2
ft.
