About Spiny restharrow
Ononis arvensis, known as bukkebeinurt in Norwegian, is a perennial herbaceous plant from the Fabaceae family, characterized by its spiny stems and delicate pink or purple flowers. It grows in low clumps and is ideal for rock gardens, sunny borders, or as part of naturalized meadows, adding a wild touch and color in late spring and summer. Its flowers attract pollinators, contributing to the surrounding biodiversity.

Care tips
This plant thrives in full sun and tolerates poor, well-drained soils, including sandy or calcareous types; waterlogging is its main enemy. Watering should be moderate, allowing the substrate to dry completely between waterings, and it is very drought-tolerant once established. It does not require regular fertilization, and a common mistake is attempting to grow it in heavy or overly wet soils, which can lead to root rot. It is a low-maintenance plant, ideal for xeriscaping.
