About Onobrychis argentea
Onobrychis argentea, also known as Silvery Sainfoin, is a low-growing perennial legume forming dense clumps. It features silvery, hairy leaves and produces spikes of pink to purple flowers in summer. This plant is ideal for rockeries, dry gardens, or as ground cover in poor soils, adding an ornamental touch and attracting pollinators.

Care tips
This plant thrives in full sun for optimal growth and prefers well-drained soils, even poor or calcareous ones, strictly avoiding waterlogging. Watering should be moderate, allowing the substrate to dry out between waterings, and very scarce once established. A common mistake is overwatering, which can lead to root rot; it is a very drought-tolerant plant.
