Capsella bursa-pastoris

Rosette (a), pointed leaves, flowers (c–e), pods (i, k)
Capsella bursa-pastoris plants grow from a rosette of lobed leaves at the base. From the base emerges a stem about 0.2–0.5 m (0.66–1.64 ft) tall, which bears a few pointed leaves which partly grasp the stem. The flowers, which appear in any month of the year in the British Isles, are white and small, 2.5 mm (0.098 in) in diameter, with four petals and six stamens. They are borne in loose racemes, and produce flattened, two-chambered seed pods known as siliques, which are triangular to heart-shaped, each containing several seeds.Like a number of other plants in several plant families, its seeds contain a substance known as mucilage, a condition known as myxospermy. Recently, this has been demonstrated experimentally to perform the function of trapping nematodes, as a form of 'protocarnivory'Capsella bursa-pastoris is closely related to the model organism such as Arabidopsis thaliana and is also used as a model organism, due to the variety of genes expressed throughout its life cycle that can be compared to genes that are well studied in A. thaliana. Unlike most flowering plants, it flowers almost all year round. Like other annual ruderals exploiting disturbed ground, C. bursa-pastoris reproduces entirely from seed, has a long soil seed bank, and short generation time, and is capable of producing several generations each year.

3-6 hours of sun per day, with protection from intense mid-day sun
