well-manured ground. They may be increased by division in October or
November, as well as in spring-time. Height, 3 ft.

thrives in any rich soil, and may be increased by division of the
root. Height, 1 ft.

Ruta Graveolens.--This hardy evergreen shrub is a species of Rue.
It enjoys a good, rich soil, in which it flowers freely in August.
Cuttings may be struck under a hand-glass. Height, 3 ft.

Ruta Patavina (_Rue of Padua_).--For rock-work this hardy perennial is
very useful. It likes a dry yet rich and light soil. At midsummer it

Saffron, Spring.--_See_ "Bulbocodium."

Sage.--This useful herb likes a rich, light soil, and is propagated by
division of the root, by cuttings, or by seed.

Saintpaulia Ionantha.--The leaves of this plant spread themselves
laterally just over the soil, forming a rosette, in the centre of
which spring up large violet-like flowers. It is a continuous bloomer.
A rather light, rich soil or vegetable mould suits it best. The seed,
which is very minute, should be sown early in spring, in gentle heat:
to prevent it being washed away, the pots may stand up to the rims in
water for a while when the ground wants moisture. Height, 1 ft.

Salix Reticulata.--A dwarf creeping plant whose dark green leaves
eminently fit it for the rock-work or carpet bedding. It will grow in
any soil, but prefers a moist one, and produces unattractive brown
flowers in September. Propagated in spring by detaching rooted
portions from the parent plant and planting them in moist, sandy loam.
Height, 2 in.

Salpiglossis.--Very beautiful half-hardy annuals which are greatly
prized for cut bloom. A light but not over-rich soil suits them best.
The seed may be sown in the open border early in spring, or preferably
on a hotbed at the same period. For early flowering raise the plants
in the autumn, and winter them in a frame or greenhouse. Flowers are
produced in July and August. Height, 2 ft.

Salsafy (_Vegetable Oyster_).--Sow the seed in any good garden
soil--deep sandy loam is best--towards the end of April in drills 1
ft. apart, and thin the plants out to a distance of 6 in. from each
other. The roots may remain in the ground till required for use, or be
