Propagation
Take semi hardwood cuttings taken from summer to autumn.

Sow fresh seed during spring and prick out when large enough to handle.
In moist areas graft onto Westringia fruiticosato avoid root rot.

Culture
Plants may require regular light pruning when young to encourage a dense habit and mature plants may be pruned after flowering.
