Oxalis is a genus of plants also known as wood-sorrel. Besides being pesky in lawns and greenhouses, certain species can be used for medicinal treatments for fever and nausea. Recently, different varieties have started to come out in the nursery industry that feature larger foliage, different foliage colors, flower size and color.
Typically the lawn variety of oxalis has yellow flowers reminiscent of a 5 petaled daisy but they can also be white and shades of pink/purple. The foliage is dark purple to green to lime green and red. The plants are popular gifts for St. Patrick’s Day because of their similarities to clover. Similar to a potato, the oxalis is planted with tuber roots. They can be found in retail either in tuber form or already grown out as a plant.
Because of their smaller sizes and annual habit (in our climate), oxalis is a perfect plant for container plantings. It is a versatile plant that can be used in combination with other plants or on its’ own in a variety of containers ranging from rustic terra-cotta to ultra sleek modern. At the end of the season, the tubers can be dug up and saved for next year or the plants can also double as indoor features for the winter.
