===Propagation===
Seed can be short lived in some species{{RHS}}, sow as fresh as possible.  Softwood cuttings can be taken of plants you like{{RHS}}.

Seeds of frost-sensitive sorts should be planted under glass in spring, then picked out and planted in individual pots of loamless or loam of medium fertility{{RHS}}.  Grow in a sunny, airy spot, free of frost, and pinch to keep compact{{RHS}}.  Plant outdoors only after danger of frost is passed, and water well.

Softwood cuttings can be taken in spring, and placed in soilless potting mix, best with some bottom heat{{RHS}}.
