Pentanema britannicum, commonly known as British Yellowhead, is a deciduous perennial or biennial herb native to temperate grasslands and open woodlands of Europe and Asia. It typically grows to a height of 1-2 feet (30-60 cm) and spreads to a similar width. The plant features lance-shaped leaves and clusters of bright yellow, daisy-like flowers that bloom in late summer to early fall, adding a splash of color to the garden when many other plants are fading. The flowers are moderately showy and attract pollinators such as bees and butterflies.

British Yellowhead is valued for its late-season blooms and its ability to thrive in poor soils with good drainage. It is often used in wildflower meadows, borders, and as part of naturalistic plantings. It requires minimal maintenance once established, making it a good choice for low-maintenance gardens. This plant prefers full sun but can tolerate light shade and needs well-drained soil. It is not known for any significant disease or pest issues, but it can self-seed prolifically, which may be considered undesirable in some settings.CC BY-SA 4.0
