Can you help me identify this houseplant please

This plant folds its leaves back at dust like a prayer plant. I love it, and would like to know what it is. Can you help please? I am attaching a photograph.

Thank you

Hi Chris,

Thin, purple triangular leaves on PurpleShamrock Plant
Purple Shamrock Plant

Your plant is called  a Purple Shamrock Plant.

Shamrock Plants, or Oxalis,  have the nickname Shamrock Plant because of their soft, thin, triangular leaves that are divided into three leaflets just like a lucky clover plant. ”Oxalis regnelli, the green leafed version of the Shamrock Plant, has small delicate white flowers while Oxalis triangularis (your plant) also called False Shamrock Plant, has dark purple leaves and pinkish lavender flowers. Shamrock Plants are bulb plants and die back after they bloom. Don’t throw them out, they just need a little rest before starting to grow again.

These plants are considered slightly poisonous if eaten in large quantities and should be kept away from pets and children. Read more about common houseplants that are poisonous in Don’t Feed Me To Your Cat! A Guide to Poisonous Houseplants.

You can find all my care tips for a Purple Shamrock plant in the Popular Houseplant section of the website. The picture is of the green variety, but the care is the same.
