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.
