About Scarlet Sage
Botanically, Salvia splendens is a fast-growing annual in the Lamiaceae family. It reaches around 40 cm tall and 30 cm wide at maturity, with evergreen foliage. Red, purple and white flowers appear for much of the year.
Where to grow Scarlet Sage
Scarlet Sage suits warm-temperate, subtropical and tropical climates and grows best in full sun and part shade or morning sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Most soils suit Scarlet Sage provided drainage is reasonable. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Scarlet Sage does best with regular, moderate watering. A light spring feed is usually enough to maintain steady growth. Keep a newly planted specimen evenly watered through its first season; established plants can then follow the water needs above.
Pruning & care
Prune Scarlet Sage after flowering to keep it compact and encourage the next flush of blooms. Expect a low maintenance care workload once it is established.
Using Scarlet Sage in the garden
Scarlet Sage earns its place for drawing nectar-feeding birds into the garden, feeding bees and pollinators, pots and courtyard containers and a feature or specimen planting. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
For easier irrigation and care, group Scarlet Sage with species that also favour regular, moderate watering and warm-temperate climate. Leave enough room for the mature spread so neighbouring plants are not crowded out.
Good to know
It is regarded as non-toxic and pet-safe.
