About Sainfoin

Onobrychis viciifolia, commonly known as Sainfoin, is a perennial forage legume prized for its hardiness and beautiful spikes of pink to purple flowers. This low-maintenance plant is ideal for water-wise gardens, wildflower meadows, or as ground cover on sunny slopes, providing rustic visual appeal and benefiting pollinators. Its delicate foliage and abundant blooms make it an excellent choice for naturalistic landscapes or xeriscaping.

Care tips

Sainfoin thrives in full sun in well-drained soils, even poor or calcareous ones, tolerating drought well once established. Although hardy, occasional watering during very dry spells can enhance its bloom. Avoid overwatering, as it is susceptible to root rot in waterlogged soils. It does not require fertilization; as a legume, it fixes its own nitrogen in the soil.
