A firm favourite for its butterfly-like leaves, Purple Shamrock or Oxalis triangularis is photophilic. This means they respond very quickly to light, folding their leaves in the evening and opening them again in the morning. Place them in a brighter spot where they get at least partial sunlight. Make sure not to overwater as too much water may send them back to dormancy. If they do get dormant, let them dry out, set them aside and wait for the first new leaf to appear then you can start watering again.
