Hey Plant Friends!

This week we are talking about Oxalis triangularis, more commonly known as purple shamrock. Oxalis is a large genus of flowering plants in the wood-sorrel family, Oxalidaceae, and are native to South America. Oxalis triangularis have distinct triangle shaped, purple foliage that dances in the sunlight. Extra bonus, have they lavender colored flowers. Shamrocks are commonly sold around St. Patrick’s Day as a seasonal plant but with the correct care they make a great houseplant. At Tonkadale, we offer the traditional green variety as well.

Let’s talk about care. Oxalis love to sit in a bright, sunny window. Morning sun is best. Oxalis are sensitive to extreme temperatures, however they do like a bit of a chill. Allow the top 1-2 inches of soil to dry before watering. Oxalis will show wilt and will recover nicely from drought. Repot using Espoma’s All Purpose Potting Mix. Oxalis go dormant in the summer, usually only for a month or so. When this happens, the foliage will die back almost all the way. Fear not, this is normal. Cut back on watering, trim back the dry foliage, and place in a cool spot. After about a month of rest, place back in a sunny window, water and watch the magic unfold as your Oxalis grows beautiful new foliage. Keep an eye out for insect pests including aphids and spider mites. Check for pests weekly when watering. Keep a bottle of Bonide’s Eight Insect Control on hand for easy treatment.

Oxalis is available at Tonkadale in 2”, 4”, and 6” pots. If you have additional questions feel free to reach out to us by phone, Instagram, or email us at hello@tonkadale.com.

Happy Planting!
