| Notes: | ||
Outdoors, Rosyleaf sage should be planted in soil that is light and somewhat fertile. Humus-rich moist soil is best, but good drainage is important. Grow in full sun to part shade, keeping in mind that those with dense/wooly leaves need full sun and particularly good drainage. Cut back water sharply in the winter. Should be heavily pruned each spring.
Indoors the plant should be grown under glass, in a potting mix with good drainage. Give it full light, with protection from strong direct sun. Water and fertilize freely while the plant is growing and blooming, but water very little in the winter, and do not fertlize.
Propagation
- Cuttings - Root basal or softwood cutting from spring to early summer. Semi-ripe cuttings can be taken as well in late summer/autumn, and given bottom heat.
- Seed - sow in spring in containers in cold frame, or in situ after frost danger is past.
- Division - divide in spring.
Pests and diseases
- Common - rust, powdery mildew, stem rot, fungal leaf spots.
- Occasional - whiteflies, mealybugs, aphids, spidermites.
Cultivars
- 'Bethellii' - has larger leaves which are also more velvety. Flowers are a bright purplish-crimson.
- 'Mulberry Jam' - smaller upright hybrid which blooms continuously from summer to frost
