Oxalis triangularis ssp. papilionacea, more commonly called "Oxalis regnelii", is a wood sorrel with fresh green leaves. It has masses of white to pale pink flowers which appear during the growing season. It is suitable for pots and hanging baskets.

Oxalis Triangularis is one of the most sought-after houseplants. They are easy to grow and mostly perennial plants, with rhizomes that profoundly grow leaves, divided into 3 leaflets like clovers, which resemble a butterfly. They flower abundantly and can be grown inside or outside.

Native to Brazil, the Royal Horticultural Society has awarded this Purple Shamrock the Award of Garden Merit.
Please note that this order only includes the bulb/rhizome and not a full plant. The bulbs look like TINY immature pinecones.

STARTING YOUR BULBS
Put a few in a pot with a rich, well-draining potting mix. Plant about 2-4 centimeters (1-2 inches) apart and 1-2 cm (1 inch) deep. Water lightly every couple of weeks until new growth appears. Sprouting happens VERY SLOWLY at first but picks up speed later.

Oxalis bloom from spring until the first frost with small light pink flowers.

In the winter, they go into hibernation mode and should be brought inside and stored in a cool, dark, dry place. They will not survive cold winters outdoors but will be perennials if taken care of properly. In spring, simply plant and give a light amount of water and sun and they will quickly wake from dormancy.

CARE
Light: Thrives in bright indirect to bright direct light.
Water: Water every 1-2 weeks, when the top 2 centimeters (1 inch) of soil becomes dry. Make sure your pot has drainage holes. Expect to water more often in brighter light and less often in lower light.
Humidity: Any humidity level will do. Normal room humidity is fine.
Temperature: Best not to let it go below 60°F (15°C).
Fertilize: Once a month during the growing season using a slow-release blend.
Pruning: Pinch off any dead foliage.
Propagation: You can get your oxalis to reproduce once a year by propagation - separation of the rhizomes.
Dormant season: Winter
