About Pink shamrock
<i>Oxalis articulata</i>, known as pink-sorrel or wood sorrel, is a perennial rhizomatous herbaceous plant characterized by its delicate, funnel-shaped pink or purple flowers, which emerge on slender stems above bright green foliage, often with a reddish tinge. Its trifoliate leaves fold up at night or under stress conditions, adding dynamic interest. It is ideal for garden borders, hanging baskets, or as ground cover in temperate zones, providing a subtle and elegant splash of color.
Native range
South America (Argentina, Brazil, Paraguay, Uruguay)
Care tips
It prefers full sun to partial shade exposure, where it will flower more profusely. Watering should be moderate, allowing the substrate to dry slightly between waterings to avoid waterlogging, especially in winter when it goes dormant. Use a well-draining substrate, rich in organic matter, and avoid heavy or clayey soils. A common mistake is overwatering during the dormant period, which can lead to rhizome rot.
