General Description

Successful in many warm soils, the spreading foliage of Ganges primrose is a lovely backdrop for the white or yellow blossoms that flush purple with maturity. An exact nativity is uncertain, but believed to hail from eastern Africa, and India eastward into Malaysia. This is a tender perennial or subshrub that sprawls out and is reminiscent of a large petunia plant. It is usually regarded as a pretty weed in the tropics (in lawns), often invasive along the beaches.

The medium green leaves are plump ovals to heart-shaped and held in opposite pairs on the creeping or clambering stems. Anytime when temperatures are warm and soil moisture ample, funnel-shaped flowers appear, opening white or yellow and becoming flushed with purple tones as they age. The blossom has five flaring lobes and will attract long-tongued moths.

Grow the Ganges primrose in full to partial sun in average to nutrient poor waste soils. Tolerant of drought and salt spray, this adds to this plant's ability to establish and attain weed status across the world's tropical regions. If selected for garden use, mulch under and around the plant to diminish its weedy tendencies. In colder regions it holds promise for use as an annual groundcover or container plant.
