If you're decorating for a St. Patrick's Day party, you'll want to include a potted shamrock plant or several shamrock houseplants. Party or not, the potted shamrock plant is an attractive indoor plant.
So what is a shamrock plant? Keep reading to find out more about growing and caring for shamrock plants.
What Is a Shamrock Plant?
The potted shamrock plant (Oxalis regnellii), a member of the wood sorrel family, is a small specimen, often reaching no more than 6 inches (15 cm.) tall. The clover-shaped leaves are available in a range of shades, including green, red or purple. Their delicate white flowers bloom off and on during fall, winter, and spring.
Shamrock plants grow from tiny bulbs that may be planted in fall or early spring. Most often, shamrock plants are purchased when foliage is growing and sometimes when in flower. People often buy them to celebrate spring holidays or to add a touch of good luck to their indoor spaces.
Many cultivars of oxalis exist, but exotic varieties provide the best indoor performance. However, don't dig a wild wood sorrel from outdoors and expect it to grow as a houseplant.
Growing Oxalis Houseplants
Oxalis thrives in bright, indirect light, preferably in a location that is cool at night (60°F) and warm during the day (70°F). The foliage has the unique ability to close its leaves during levels of low light, whether at night or on cloudy days. This behavior serves as a defense mechanism against excessive light. If you notice this, consider relocating the plant to a shadier spot or provide protection from intense sunlight.
Ensure it's planted in well-drained potting mix within a container that has proper drainage. While this plant prefers to be somewhat "pot bound," it's important to avoid overwatering and ensure the soil remains consistently moist, but not wet. Water two to three times a month, allowing soil to dry out between waterings.

Fertilize after watering with a balanced houseplant food. Plants can be fertilized with a diluted solution once during the growing season and after flowering. There is no need to apply fertilizer in the winter months or when the plant is dormant.
Summer Dormancy
Caring for shamrock plants is simple when you understand their periods of dormancy. Unlike most houseplants, the potted shamrock plant goes dormant in summer. When leaves die back, the potted shamrock plant needs a time of darkness to rest. Caring for shamrock plants during the period of dormancy includes limited watering and withholding of fertilizer.
The dormant period lasts anywhere from a few weeks to three months, depending on the cultivar and the conditions. New shoots appear when dormancy is broken. At this time, move shamrock houseplants to a sunny window or other area of bright light. Resume caring for shamrock plants to be rewarded with an abundance of the attractive foliage and blooms.
Now that you've learned what is a shamrock plant and how to care for a growing Oxalis houseplant, include one in your indoor collection for winter blooms and maybe good luck.
