This herbaceous perennial forms a compact rosette of thick, fleshy, oval leaves that are dark-green, hairy, and often display pronounced veins and wavy margins. It produces clusters of trumpet-shaped, five-lobed flowers, typically light to medium blue or violet-blue, on slender stalks. As a lithophyte, it naturally thrives on rocky outcrops in its native southeastern Kenya, blooming almost all year round.
Where it works in Kilifi
In a Kilifi-coast garden, this lithophytic herb thrives in bright, indirect light, ideally sheltered from direct midday sun. It requires fertile, humus-rich, well-draining soil and benefits from high humidity, making it suitable for rock gardens, shaded planters, or as an understory specimen in humid microclimates.
Growing notes
This species prefers consistent warmth and moderate watering, allowing the soil to dry slightly between applications. Avoid wetting the hairy leaves to prevent rot or fungal infections. It is hardy in frost-free conditions (USDA Zones 9-11) and benefits from regular deadheading to encourage continuous flowering. Growth can be slow initially.
