Its delicate purple or white flowers, often appearing solitary or in small clusters, add a touch of rustic charm. It is ideal for improving soil health in vegetable gardens, cultivated fields, or as a ground cover in naturalistic garden settings.

Care tips
This species thrives in full sun for optimal growth, though it tolerates some partial shade. It requires moderate watering, ensuring the soil remains moist but not waterlogged, especially during its establishment phase. It adapts well to a wide range of well-drained soils, including poor or clayey ones. A common mistake is planting it in overly nitrogen-rich soils, which can diminish its ability to fix atmospheric nitrogen.
