Trifolium echinatum, commonly known as Hedgehog Clover, is an annual or biennial herb native to the Mediterranean region, particularly thriving in open grasslands, meadows, and pastures. It is adapted to a Mediterranean climate with wet winters and dry summers. This species typically grows at a moderate rate to a height and width of 0.5-1.5 feet (0.15-0.5 meters). Hedgehog Clover is characterized by its distinctive spiny, globular flower heads, which are pink or red and bloom profusely in the spring and summer, attracting pollinators. The plant’s common names, such as Prickly Clover and Spiny Clover, refer to the spiky appearance of the flower heads.

Hedgehog Clover is valued for its unique texture and color in wildflower meadows and informal garden settings. It is drought-tolerant once established, making it suitable for xeriscaping and low-water gardens. It is also used as a cover crop or green manure due to its ability to fix nitrogen in the soil, which improves soil fertility. For successful cultivation, it requires full sun exposure and well-drained sandy or loamy soils. While it is generally low-maintenance, it can be susceptible to root rot in poorly drained conditions and may attract pests such as aphids.CC BY-SA 4.0
