原生地・分布（英語）:

説明（英語）: Genus of about 150 species of evergreen shrubs, subshrubs, and annuals from grassland, rocky places, moist sites, and forest margins in tropical Africa and South Africa. Their simple, often very narrow leaves are usually clustered or solitary, and borne at alternate nodes or occasionally in opposite pairs. Selagos are grown mainly for their heads, spikes, corymbs, or panicles of usually small, tubular flowers, each with 5 spreading petal lobes. In frost-prone climates, grow in a temperate greenhouse. In milder areas, grow at the front of a shrub border, in a raised bed, or at the base of a warm, sunny wall. S. serrata is also effective grown in a container in a courtyard garden.

耐寒性（英語）: Frost tender, although some may survive temperatures near 0°C (32°F).
