Are Shamrock Plants Indoor or Outdoor Plants?

With their iconic three-leaved shape, shamrock plants (Oxalis triangularis) are a beloved symbol of Irish culture and often serve as the traditional plant for St. Patrick’s Day celebrations. But what exactly are shamrocks and can you grow them inside or outside of your home?

Shamrock plants are a type of wood sorrel in the Oxalis genus and native to Brazil. While most species have green foliage, there are also yellow, pink, and purple varieties.

As perennials, they reach heights of 6-8 inches with a spread of 12 inches. The clover-shaped leaves open during the day and close at night, giving them a unique look.

When it comes to care, shamrocks prefer bright indirect light and well-draining soil. Overwatering can lead to root rot so it’s best to wait until the top inch or two of soil has dried out before watering again. They’re also susceptible to pests such as mealybugs and spider mites so make sure to check regularly for signs of infestation.

The biggest question is whether shamrock plants make good indoor or outdoor plants. The short answer is both! These resilient little plants can survive in both indoor and outdoor conditions, provided that they receive adequate sunlight and moisture levels are monitored carefully.


Shamrock plants (Oxalis triangularis) are a beautiful addition to any home or garden due to their unique appearance and cultural significance. Although they can be grown indoors or outdoors, they require bright indirect light and well-draining soil in order to thrive. With the right care, you can enjoy your own lucky shamrocks year after year!
