Babiana ambigua is a small South African geophyte from the Iris family that grows from a corm, producing fragrant blue to mauve flowers each year. It needs winter-wet, summer-dry conditions and sun, and is typically grown from corms in bulb gardens.

About
Babiana ambigua is a species of plant in the Iridaceae. It is endemic to the Western Cape province of South Africa. It is a geophyte, that appears from an underground corm every year and grows to a height of 5–8 cm (2.0–3.1 in) or occasionally up to 16 cm (6.3 in). Its leaves are pleated, hairy, lance-shaped, reaching higher than the inflorescence. The fragrant, mirror-symmetric, blue to mauve flowers, consist of six tepals merged into a tube at their base, but with free lobes at the top. The lower lateral tepals have whitish markings accentuated by a more intense blue line along their margin. Each flower is supported by two green bracts sometimes with a brownish tip, and the inner bract is divided entirely to its base. There are three anthers crowded to the dorsal side of the perianth and a style divided in three branches on top of a smooth ovary.
Where it grows
Babiana ambigua can be found in the mountains and the coastal belt of the Western Cape province of South Africa between Riversdale in the southeast and the Gifberg in the northwest. It grows in fynbos and renosterveld on different kinds of soils, including the deep coastal sands of the strandveld habitat, mountain slopes and flats with a rocky sandstone underground, and renosterveld vegetation on granite-derived soils. Urban development in low-lying coastal areas and alien invasives threatened some subpopulations. But this species is still too common and too widespread, and many subpopulations are present in safe mountain habitat, therefore it is considered a least-concern species.
