Plant Profile: Oxalis articulata

Among the various species of Oxalis, Pink Oxalis, also known as Woods Sorrel, stands out as a charming, traditional plant. This deciduous perennial features a dense, mounded growth habit, reaching heights of up to 1 foot. Its flowers, often partially hidden by the lush foliage, make it a popular choice for indoor pots and as a border perennial. Notably, the leaves and flowers fold up at night. During particularly dry and hot summers, the plant may enter dormancy if not adequately watered. While the leaves contain oxalates that are considered toxic, the effects are localized rather than systemic. Pink Oxalis thrives in conditions ranging from full sun to partial shade and can endure dry soil, although it will go dormant under such circumstances. Ideally, it prefers moist, well-drained soil. Established plants develop rounded clumps adorned with numerous vibrant pink flowers, blooming once in spring and again in fall. This resilient plant is nearly indestructible and can easily be shared with friends through its small, bulb-like rhizomes. Additionally, it is relatively free from pests.

For optimal growth, Pink Oxalis flourishes in full sun to partial shade and can adapt to both moist and dry soil conditions. Propagation can be achieved by dividing the bulb-like rhizomes in either fall or spring.
