About Black and Blue Sage
Botanically, Salvia guaranitica 'Black and Blue' is a fast-growing perennial in the Lamiaceae family. It reaches around 1.5 m tall and 1 m wide at maturity, with aromatic and deciduous foliage. Blue flowers appear for much of the year.
Where to grow Black and Blue Sage
Black and Blue Sage suits warm-temperate and subtropical 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. It also is a genuinely water-wise choice.
Soil & planting
Black and Blue Sage does best in free-draining soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Black and Blue Sage does best with regular, moderate watering. A light spring feed is usually enough to maintain steady growth. New plantings need closer moisture checks in hot or windy weather, with watering tapered once strong new growth appears.
Pruning & care
Prune Black and Blue 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 Black and Blue Sage in the garden
Black and Blue Sage earns its place for drawing nectar-feeding birds into the garden, feeding bees and pollinators and a feature or specimen planting.
Companion planting & design
For easier irrigation and care, group Black and Blue 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.
