Caring Tips


Allow the soil to dry between watering, ensure the top 2cm of soil is dry before watering.


Keep your Oxalis Triangularis in a filtered bright to medium light but away from direct light. It grows well in morning light (i.e. East window). It is fairly hard to burn since Oxalis grows outdoors, the glass in your windows will filter out a lot of the intensity of the light, however it will grow best when it’s away from direct sunlight.


The striking purple leaves stand out amongst green indoor plants and it’s also photophilic, which mean that the leaves open and close in response to light in a process called nystinasty. At night the leaves fold down and during the day they will open up. Oxalis Triangularis is fairly low maintenance.
Oxalis is a genus of the wood sorrel family and is well known for being an invasive weed in most gardens. However, there are some varieties of Oxalis that are perfectly well behaved and don’t spread all over the places, such as the Oxalis Triangularis. Oxalis is often referred to as a purple shamrock or false shamrock.
