o cut away the flower-stems and to divide the
roots every two or three years. The plants may be forced for winter
use.

Southernwood (_Artemisia Arborea_).--Any soil suits this odoriferous
bush, and it is readily increased by cuttings or by division.

Sparaxis.--Closely allied to the Ixias, equally beautiful and varied
in colour, but rather dwarfer and compact in growth. Invaluable for
pot-culture. For outdoor cultivation plant them early in September,
5 or 6 in. deep, on a sheltered border, in rich, well-drained, loamy
soil. Protect from frost and wet in the winter, but keep the roots
moist while they are growing. For indoor cultivation plant four to six
bulbs in a 5-in. pot, plunge in ashes in a cold frame, withholding
water till the plants appear. When making full growth remove them to
a sunny window or conservatory, and water them carefully. They will
bloom in March or April. Height, 3 ft.

Sparmannia Africana.--An exceedingly handsome and attractive
greenhouse evergreen shrub, thriving best in loam and peat. Cuttings
may be struck in sand under glass. May is its flowering season.
Height, 10 ft.

Spartium Junceum(_Yellow Broom_).--A hardy evergreen shrub which will
grow in any soil, and is propagated by seeds. It flowers in August.
Height, 6 ft.

Specularia Speculum.--_See_ "Venus's Looking-Glass."

Spergula Pilfera.--May be grown in any moist situation in sandy soil.
It is of little value.

Sphenogyne Speciosa.--An elegant hardy annual. Sow the seed early in
spring on a gentle hotbed in loam and peat, harden off, and transplant
at the end of May to a soil composed of loam and leaf-mould, if peat
cannot be obtained. The bloom is produced in July. Height, 1 ft.

Spider Wort.--_See_ "Commelina" _and_ "Tradescantia."

Spigelia Marilandica.--From August to October this hardy perennial
produces tubular crimson and yellow flowers. It finds a congenial home
in damp peat, shaded from the sun, and may be propagated by cuttings
in loam and peat under glass. Height, 1 ft.

Spinach.--For summer use sow the round-seeded kinds at intervals of
two or three weeks from February to the end of July in rows 1 ft.
apart, cover with the finest of soil, and thin out to a distance of 3
or 4 in. In dry weather give a liberal supply of manure water. Pull
before it runs to seed. For winter use sow the prickly-seeded variety
in August and September, and thin the plants out 9 in. apart. If the
ground is hot and dry, the seed should
