Oxalis triangularis subsp. papilionaceae: Silver Butterfly Oxalis

Oxalis triangularis subsp. papilionaceae, often sold as 'Silver Butterfly' or Purpleleaf False Shamrock, is a captivating bulbous perennial grown for its stunning foliage. Each leaf comprises three deep purple, triangular leaflets with a distinctive silver or pale green central marking, creating a butterfly-like appearance. The leaves fold down at night or in low light (nyctinasty). Delicate, pale pink to white, trumpet-shaped flowers bloom intermittently above the foliage.

Plant Profile

This plant thrives in bright, indirect light and well-drained potting mix. It goes through a natural dormancy period, usually in summer or winter, when the foliage dies back. During dormancy, reduce watering and store the bulbs cool and dry until new growth emerges. It makes an excellent houseplant or seasonal outdoor container specimen in frost-free climates. Note: all parts contain oxalic acid and can be toxic if ingested in large quantities.
