Garden Bloggers Bloom Day: Shamrock Plants

Although it looks like a three-leaf clover because of its trifoliate leaf structure, a shamrock plant is actually a species of Oxalis. These green or burgundy foliage plants are often sold as novelty houseplants, especially around St. Patrick’s Day. The small flowers rise high above the leaves with five white or pink to white petals. Most people grow them as houseplants but they can be grown outdoors in the summer here in Virginia. Because they are small, it is best to grow them in containers (off the ground level) for better viewing. Shamrock plants grow from rhizomes called pips which can rot if overwatered so it is best to let the soil dry out a little between watering. Eventually the plant will go through a dormant period and produce more pips that can be dug up for more plants.

The plant is best grown in indirect light with cool temperatures. Usually it is only after you purchase the plant that you learn of its charm:  the leaves move up and down every day. In the daytime, at maximum light, the leaves are horizontal or open. By nightfall, when light levels are reduced, the leaves bend down almost as if the plant is wilting. Don’t worry, this is normal and does not mean that you have to water.

Shamrocks are beautiful houseplants but there is one caveat: they do not combine well with pets. Oxalis contains a high level of oxalic acid, which can be poisonous.
