Safety Overview
1.Shepherds Purse — Plant Snapshot
Shepherds Purse, scientifically known as Capsella bursa-pastoris, is a ubiquitous annual or biennial herb belonging to the Brassicaceae family, often recognized as a common weed across temperate regions worldwide. Native to Eurasia, its remarkable adaptability has allowed it to naturalize on every continent, thriving in disturbed soils, roadsides, gardens, and agricultural fields. Morphologically, it typically forms a basal rosette of deeply lobed leaves, resembling dandelion leaves, from which a slender, erect stem emerges, reaching heights of 10 to 50 centimeters.
The stem bears smaller, sessile, arrow-shaped leaves that clasp the stem. Its small, white, four-petaled flowers are arranged in terminal racemes, blooming almost year-round in milder climates. The most distinctive feature of Capsella bursa-pastoris, and the origin of its common name, is its unique, heart-shaped or triangular-obcordate silicle fruit, which resembles a medieval shepherd’s purse.
This fruit contains numerous small, yellowish-brown seeds. The entire plant, including the roots, leaves, and seeds, has a slightly pungent, peppery taste characteristic of the mustard family, indicating its rich content of sulfur-containing compounds. Its widespread presence and distinctive morphology make it easily identifiable, contributing to its long history of traditional use in various folk medicine systems globally.

11.Shepherds Purse — Propagation & Care
- ✓Soil Preference — Shepherds Purse thrives in well-drained, average to poor soils, tolerating a wide range of soil types from sandy to clayey, as long as compaction is not excessive.
- ✓Sunlight Requirements — It prefers full sun exposure, meaning at least 6-8 hours of direct sunlight daily, though it can tolerate partial shade, which may reduce its vigor.
- ✓Water Needs — This plant is quite drought-tolerant once established, requiring minimal watering; however, consistent moisture during germination and early growth promotes healthier development.
- ✓Propagation — Primarily propagated by seeds, which can be sown directly in the garden in early spring or late autumn; it readily self-seeds, often becoming naturalized.
- ✓Temperature Tolerance — Shepherds Purse is hardy and can withstand a wide range of temperatures, often germinating in cool weather and persisting through light frosts.
