Exposure
This is the average amount of sunlight that a plant needs to thrive.

Plants may tolerate more sunlight in cooler climates and need afternoon shade in extremely hot climates.
Full sun
Soil type
This is the kind of soil that a plant needs to thrive. Most plants require a well-drained soil that allows the water to soak into the soil without becoming soggy. Sandy and clay soils can be improved by digging in compost to improve drainage.
Well drained
Water needs
Plants have specific water requirements. Water loving means the plant needs regular watering to keep the soil moist. Average generally indicates applying 1 inch of water per week, or watering when the soil is dry to a depth of 3 to 4 inches. One inch of water is equal to 5 gallons per square yard of soil surface.

(Coastal Blue Sage) Native from the sandy shores to brushy slopes of South Africa's East Cape, this sub-shrub sage is noted for growing easily in gardens elsewhere. Its lovely purplish-pink flowers have a subtle blue sparkle in bright sun and bloom spring to fall.

Sub-shrubs are perennials with woody stems as well as soft herbaceous growth. This one has heavily lobed, lyre-shaped leaves. They are a deep green, which is unusual for Salvias from South Africa where velvety hairs often make foliage appear silvery and also help conserve moisture. Scabra refers to the roughness of this plant's leaves.

In its homeland, the fuzzy flower spikes of Coastal Blue Sage grow up to 36 inches above the clumping, basal foliage. In USDA Zones 8 to 11, you can expect heights of 18 to 24 inches with a spread of 24 inches. Give this sage full sun, any well-drained soil and average watering based on local conditions.

Use this lovely little sage as a small-scale groundcover, container plant or front-of-border selection. It grows particularly well in dry gardens. This plant deserves wider use.
