Salvia: Greenhouse Plants
C – cool, minimum of 7°C (45°F) / W – warm, minimum of 13°C (55°F)
There are several species of Salvia which need greenhouse treatment or make good greenhouse plants and they are all easy and fast growing. My personal favourite is Salvia leucantha from Mexico which makes a small shrub of 60-90 cm (2-3 ft). The flowers which appear during winter are covered in white and deep-violet wool in a most attractive way. Once a plant is established it can be kept going from year to year by cutting the shoots back hard after flowering or in the spring each year. Cuttings are not difficult to root and seed can be sown at the surface of theat 21-26°C (70-80°F).
