Ledum (_Labrador Tea_).--Low-growing American evergreen shrubs,
thriving best in sandy peat, and may be increased by layers.
Leek.--Sow early in March, and prick out the plants in rich soil, in a
sheltered position, to strengthen. As soon as they are large enough,
plant them out in very rich, light ground in drills 6 in. between each
plant and the rows 18 in. apart. For large exhibition Leeks sow in
boxes in February, under glass. Plant out in June in trenches 15 in.
wide and 18 in. deep, with plenty of old manure at the bottom of the
trench and 6 in. of good light mould on the top of it. Gradually earth
up as the stems grow. Water liberally in dry weather, and give a
little weak liquid manure occasionally.
Leontopodium.--Hardy perennials, succeeding best in peat soil. They
are most suitable for rock-work, and may be increased by seed or
division of the roots. Bloom is produced in June. Height, 6 in.
