and are
increased by division. Height, from 9 in. to 1 ft.

Sauromatum Guttatum.--This makes a good window or cool greenhouse
plant. Pot the tuber in good loam and leaf-soil, and keep the mould
only just damp until the foliage, which follows the flowers, appears.
When the foliage fails, keep the tubers dry till spring. If grown out
of doors the tubers must be lifted before frost sets in.

Savoys.--Sow the seed in March or April, and when the plants are 2 in.
high remove them to a nursery-bed, selecting the strongest first. Let
them remain till they are about 6 in. high, then transplant them, 18
in. apart, in well-manured soil. Their flavour is greatly improved if
they are frozen before being cut for use.

Saxifrage.--These beautiful Alpine perennials delight in a light,
sandy soil, and are easily propagated by seed or division. It is most
convenient to grow the rare and tender kinds in pots, as they require
the protection of a frame in winter. Saxifraga Sibthorpii is very
suitable for the lower and damper parts of rock-work; it is hardy, and
sheds its seed freely. S. Umbrosa (London Pride) makes a neat border,
and is also useful for rock-work. S. Sarmentosa (Mother-of-Thousands)
is a fine hanging plant for greenhouse or window. They flower in
April. Height, mostly 4 in. to 6 in., but some grow as high as 1-1/2
ft.

Scabious.--Ornamental and floriferous hardy biennials, which grow
freely in common soil. The seed may be sown at any time between March
and midsummer; transplant in the autumn. They bloom in June. Height, 1
ft to 3 ft. (_See also_ "Cephalaria.")

Scale.--Red Scale may be easily overcome with a strong solution of
soft soap applied with a sponge. White Scale is harder to deal with.
Syringe frequently with strong soapsuds heated to 120 degrees. If the
plant is badly attacked it is best to destroy it.

Schizanthus.--Extremely beautiful and showy annuals. A rather poor,
light soil is most suitable for their growth. For early flowering sow
the seed in autumn, and keep the young plants in a frame or greenhouse
throughout the winter. For a succession of bloom sow in the open
border early in the spring. They flower in July and August. Height, 2
ft.

Schizopetalum.--This singular and delightfully fragrant annual
does best in a mixture of loam, peat, and sand, or sandy loam and
leaf-mould. Sow the seed in pots in the spring, place in a greenhouse,
and when large enough to handle, plant out in the open border,
