Oxalis stricta
species of plant

Oxalis stricta, called the common yellow woodsorrel (or simply yellow woodsorrel), common yellow oxalis, or upright yellow-sorrel is a herbaceous plant.
Habitat
O. stricta is native to North America and East Asia and has been introduced elsewhere, especially in Europe. It was not documented in Michigan before the 1890s.
It tends to grow in woodlands, meadows, and in disturbed areas as both a perennial and annual. and generally requires dry or moist, alkaline soils, preferring sandy and loamy dirt to grow in. It requires well-drained soil and can grow in nutritionally poor grounds.
Commonly considered a weed of gardens, fields, and lawns, it grows in full sun or shade.
Description
Upright yellow woodsorrel is an annual or short-lived perennial plant that has short rhizomes, but never has bulbs. The alternate leaves of this plant are divided into three distinctively heart-shaped leaflets (a typical trait of other species of Oxalis) that can grow up to 2 cm (0.79 in) wide. These leaves curl up at night (exhibiting nyctinasty), and open in the day to perform photosynthesis.
The public source identifies “Oxalis stricta” as species of plant. This brief keeps that definition visible, then builds a research path around Oxalis, stricta and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Oxalis stricta”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q158332. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
