Salvia leucantha, the Mexican Bush Sage, is a member of the Lamiaceae family that originally comes from Mexico and tropical America – but you can see it in the chillier climate of the Hayrick border in the Parks. It is a tender sub-shrub which grows to around 1.2 metres tall. It is ideal for use as a highlight plant in a herbaceous border or cottage garden. It has narrow, deep-veined leaves which are a bluey-green colour, and bears long, downy purple and white flowers from mid-summer until the first autumn frost.
Mexican Bush Sage grows best in full sun, but will tolerate partial shade. A sheltered position will help keep the flowers looking their best. The soil should be moist but well drained. Prune back to healthy shoots in early spring and protect from frost in a greenhouse during the winter. To propagate new plants, take softwood cuttings in the spring or semi-ripe hardwood cuttings in the autumn.
