These grow best in a mixture of sandy loam and peat ordecayed vegetable soil. The annuals may be sown either in autumn,
and wintered in a frame, or in the open in April. The perennials are
increased by seed or by division
of the root, and young cuttings
of the branching species root freely if planted under glass. S.
Ocymoides, on account of its trailing nature, and S. Calabrica make
fine rock-work plants. The leaves of S. Officinalis, or Soap Plant, if
stirred in water form a lather strong enough to remove grease spots.
They bloom in June and July. Height, 6 in. to 2 ft.
