In winter, the plant should not be watered. The plant measures about 15cm (6in) in height. Without stems, it develops leaves carried by a long petiole emerging directly from the rhizome. The leaf is divided into 3 generally triangular leaflets, arranged in the same plane perpendicular to the petiole. The leaves orient themselves by following the light: they close on the petiole in the evening and spread out at sunrise.

Each umbel bears 2 to 9 small flowers that start off pale pink, funnel-shaped and spreading into 5 rounded lobes.
