Streptocarpus (Cape Primrose).--This plant is a greenhouse
perennial, showing great variety of colours, from white to violet
and crimson, and is of neat habit. A light and rather rich soil or
vegetable mould suits it best. Seed sown in February in slight heat
will produce plants for flowering in July; that sown in March or April
will flower in August and September. Grow slowly in small pots, and
in February put them in their flowering pots. Give plenty of air and
shade them from the sun. It may also be increased by division, or
leaf-cuttings may be taken under a bell-glass. The plants like plenty
of water, but need good drainage. Height, 9 in.
Streptosolen Jamesoni.--A good compost for this greenhouse evergreen
shrub is two parts sandy loam, one part leaf-mould, and a little
silver sand. During growth it needs a liberal supply of water and to
be kept near the glass; only a small amount of moisture should be
given in winter. In March cut it into shape, and re-pot it as soon as
new growth starts. During the summer syringe it frequently to keep off
red spider, and during winter maintain a temperature of 55 degrees.
Stylophorum (Celandine Poppy, or Poppywort).--During May and June
this hardy and handsome plant produces fine yellow flowers. It
accommodates itself to any soil, but prefers a rich, light one, and
can be increased by seed sown in autumn or early spring. Height, 1-1/2
ft.
Styrax.--Ornamental shrubs requiring a light soil for their
cultivation. S. Japonica has Snowdrop-like flowers, and S. Obasa
Lily-of-the-Valley-like scented flowers. They are best propagated by
layers. Height, 4 ft. to 10 ft.
Sunflower.--See "Helianthus."
Swainsonia Galegifolia Alba.--A graceful and charming cool greenhouse
plant, with Fern-like evergreen foliage and pure white flowers, which
are borne from April to November. The soil most suitable for it is a
mixture of loam and sandy peat. Cuttings of the young growth planted
in sand under glass strike readily. Height, 2 ft.
