Smokey Jazz Salvia / Smokey Jazz Sage

Family: Lamiaceae
Origin: Hybrid selection (South American ancestry)

Overview

A dramatic, long-flowering salvia ideal for Adelaide’s hot, dry Mediterranean climate, Salvia ‘Smokey Jazz’ is prized for its deep, smoky burgundy–purple flowers displayed on near-black stems. Offering a moodier palette than other guaranitica types, it forms a compact, rounded shrub with softly aromatic green foliage that releases a fresh herbal scent when brushed. Flowering from late spring through autumn, it provides exceptional seasonal colour and thrives with minimal water once established. Heat-tolerant, pollinator-attracting and easy to maintain, it’s a standout for SA gardeners seeking rich tones and year-round presence.
