Round-leaved restharrow

Round-leaved restharrow (Ononis rotundifolia) is an attractive dwarf shrub grown for its elegant leaves and pink-white flowers which attract many pollinating insects. Both the common name, "round-leaved restharrow," and the Latin name, Ononis rotundifolia, refer to the leaves which are almost circular in shape. The plant thrives in rock gardens since these resemble its native rocky hillside habitats. It looks similar to Ononis fruticosa but has more rounded leaflets.

Water: Round-leaved restharrow originates from Mediterranean arid landscapes, exhibiting exceptional drought tolerance. It requires minimal hydration, ideally watered twice a week. Thriving in full sun and well-draining soil, round-leaved restharrow is best suited for outdoor cultivation, reflecting its natural dry habitat.

Fertilize: To enhance growth and flowering, round-leaved restharrow requires alternating fertilization with balanced (e.g., 10-10-10) and high-nitrogen fertilizers monthly during the growing season. Apply half-strength doses, stop in late summer for dormancy, and ensure thorough watering before and after fertilizing.

Pruning: Round-leaved restharrow has round leaves and vibrant flowers. Prune in early spring to remove dead stems and thin overcrowded areas for better air circulation. Regular pruning promotes healthy growth and blooms. Watch for diseases and avoid heavy pruning in late spring to minimize stress.

Propagation: To propagate round-leaved restharrow, use healthy, non-flowering shoot cuttings. Cut at a node, apply rooting hormone, and plant in well-draining soil. Mist to maintain humidity until roots develop. Proper handling and sufficient light are essential for establishing robust new growth.
