Oxalis triangularis
Light requirement
Suits east or west-facing rooms, or 2–3 m back from a brighter window.
Deep purple, butterfly-shaped leaves that fold up at night and open again each morning. Charming and rhythmic to live with — grows from a small corm and bounces back cheerfully from dormancy.

Reliable in most indoor environments with regular watering.
