Salvia splendens is native to Brazil, and is generally grown as a half hardy annual in many areas of the UK.
Depending upon variety they grow from about 200mm - 900mm (8"-36") high.
The smaller growing varieties make good container plants.
Alternatively a taller variety can be set in the centre of the container to give height to the feature,and a lower growing variety of salvia or some other annual placed around its base.
Week 9: Sow seed on the surface of pots / trays of seed compost and germinate at a temperature of 22°C (72°F).
Germination should take about seven to ten days.
Week 12-13: When large enough to handle prick out into cell trays or boxes and grow on at a temperature of 16°-18°C (61°-64°F) for two to three weeks, then gradually harden them off until planting out time.
Week 21: Subject to variety, plant our 200-300mm (8"-12) apart in fertile well drained soil in a sunny or partally shaded spot.
Pinch out the tops to encourage branching.
