Oxalis Triangularis, also known as the Purple Shamrock or False Shamrock, is a beautifully decorative houseplant that’s prized for its vivid purple leaves and unusual movement. A native of Brazil’s tropical forests, this easy-care plant brings something a little magical to your indoor space — with leaves that open by day and close at night.

This compact, rhizomatous perennial features delicate, triangular leaves made up of three heart-shaped leaflets. Each leaf reacts to light, folding up at night and reopening in the morning — a natural behaviour called nyctinasty. It’s a true conversation starter.

Our Oxalis Triangularis comes in a nursery pot sized W11cm x H15cm, making it perfect for shelves, side tables, or grouped displays.

Native habitat and growth patterns
In the wild, Oxalis grows on the forest floor in warm, bright, filtered light. Indoors, it prefers a well-drained soil mix rich in organic matter and does best in bright, indirect light. It may occasionally flower with delicate pale pink or white bell-shaped blooms.

Seasonal dormancy — don’t panic!
Oxalis Triangularis naturally goes dormant, often in late summer or winter. Leaves will die back — but this is part of its life cycle, not a sign of trouble.
Here’s what to do:

  • Stop watering and allow the leaves to die back

  • Keep the pot in a cool, dry spot

  • Wait for signs of new growth, then resume watering and place it in a bright location

Styling ideas

  • Display in ceramic or terracotta pots for contrast with the foliage

  • Use in trailing shelves or as a centrepiece in a grouping

  • Pairs beautifully with other colourful foliage plants like Calatheas or Marantas

Oxalis Triangularis care guide

Light requirements:
Thrives in bright, indirect light. Avoid intense midday sun but don’t keep it in deep shade.

Watering:
Water when the top few inches of soil are dry. Use a pot with drainage and a standard premium indoor potting mix. Avoid letting the plant sit in water.

Feeding:
Feed monthly in spring and summer with a gentle, organic fertiliser. We recommend our Original Vegan Plant Food, made from seaweed and natural extracts — perfect for delicate foliage plants like Oxalis.

Pet safety:
Oxalis can be toxic to pets if ingested, so it’s best to place it out of reach of curious cats or dogs.

Propagation:
Easy to propagate via rhizome division. Just separate the small bulbs and replant in fresh soil — a great way to multiply your collection.

FAQs

Well made brackets
Size: 11.25“, Color: black-6 pack, Size: 11.25“, Color: black-6 pack
These are nicely manufactured in that they are all exactly the same (with no variations) and with nice countersunk holes for the provided black flat head wood screws. I used a stained 1x12 #2 whitewood (Eastern Pine) from Lowes for the shelves. With these brackets solidly installed into wall studs at 32" on center (every other stud) the 1x12 shelf will easily support a heavy book load. I like the look better than the brackets that have the vertical leg below the shelf. It looks a lot cleaner. It is probably inevitable that your stud layout will result in a bracket or two needing to be installed between solid wood studs. In this case, do NOT use the sheetrock wall anchors provided with the brackets as they will pull out of the wall under an appreciable load. Instead, get some "Snaptoggle" toggle bolts and replace the provided bolts with #10-24 x 1.25" flat head machine screws in black. These toggle bolts are incredibly strong and easy to install. I am adding a postscript to my review regarding bracket spacing recommendations. With a heavy book load, the 1x12 shelf boards don't sag with the brackets spaced 32" apart, however I have found that the brackets themselves are overstressed by about 30% (they are only rated at 80# each.) Heavy books weigh up to about 36# per lineal foot so the maximum spacing of the brackets should be 24" apart. At 32" apart, they won't pull out of the wall if they are fastened into studs but they will sag a little bit back to front under this load. So I added additional brackets in between the installed brackets and now they are 16" apart at the heavy book shelf. The load on each bracket is now less than 50# but they STILL sag about 3/16" from back to front when loaded with books! No danger of structural failure and the sag is not really noticeable.

Very sturdy and all hardware needed
Size: 9.25”, Color: black-12 pack
These brackets are very sturdy and came with all the hardware needed, including two types of wall anchors if you won’t be going through a stud, and a magnetic level which was very useful. Would recommend.
