Cyanotis

Cyanotis is a genus of flowering plants in the family Acanthaceae. The genus includes several herbaceous, creeping or trailing species that are commonly grown as ornamental groundcovers, in rock gardens, or as hanging plants in containers. Plants have small, opposite leaves and slender stems that can root at the nodes. Flowers are usually small and tubular, and are commonly blue or purple, though colors may vary among species.

Distribution and habitat: Cyanotis species occur in tropical and subtropical regions of Africa and Asia. They are valued in cultivation for their dense foliage and their cascading habit. In cultivation they prefer warm conditions, bright but indirect light, and well-drained soil. They tolerate regular watering but do not thrive in waterlogged pots; good humidity helps but is not mandatory in all environments.

Cultivation and propagation: These plants are propagated by division or stem cuttings, and seeds are possible for some species. Provide bright light to maintain compact growth and vibrant foliage. Avoid exposing them to harsh, direct sun in hot climates, and ensure the potting mix drains well to prevent root rot. They generally require regular watering during the growing season and reduced watering in dormancy, depending on the species and climate.

Selected species: The genus comprises several species, including Cyanotis somaliensis, which is among the better known in cultivation.
