This plant is not currently available, however, propagation is planned/underway. Please sign up for the waitlist below to receive updates on availability.

This spiny member of the pea family may not be the most collectible plant out there, but it is one of the toughest. It thrives in dry, infertile, sandy, sloped situations and makes it through the cold, wet winters of the northeast like a champ. Best planted en masse for a stunning flower display.

Spiny restharrow has typical pea-like flowers in light rose and purple shades and trifoliate leaves. It is high in calcium and potassium, fixes nitrogen, and helps to improve moisture in poor, sandy soils.

Growing tip: plant when small and do not attempt to relocate. Long roots sincerely resent disturbance.
