Trifolium patens, commonly known as Azure Clover or Blue Shamrock, is an annual herb native to temperate regions across Europe. It thrives in a variety of habitats including meadows, grasslands, and open woodlands, where it contributes to the nitrogen content of the soil through its symbiotic relationship with nitrogen-fixing bacteria. This plant typically grows at a moderate rate to a height of 0.6-1.6 feet (0.18-0.5 meters) and a width of 0.5-1 feet (0.2-0.3 meters). The Azure Clover is characterized by its trifoliate leaves and showy blue or purple flowers that bloom profusely in the spring and summer, adding a splash of color to the landscape.

Azure Clover is valued for its ornamental flowers and its ability to fix nitrogen, which can improve soil fertility. It is often used in wildflower meadows, as a cover crop, or in pollinator gardens to attract bees and other beneficial insects. In cultivation, it prefers full sun to part shade and adapts well to a range of soil types, including clay, loam, or sandy soils, provided they have medium drainage. While it requires medium amounts of water, it is relatively low maintenance and can tolerate some drought once established. However, it can be susceptible to root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
