Kirlow Indigo (Indigofera kirilowii): A Long-Blooming, Spreading Perennial

Kirlow indigo forms a graceful, spreading mound that blooms on and off all summer with pinkish-purple pea-like flowers. It spreads slowly by underground roots, making it easy to divide and share "babies." Thrives in borders, rock gardens, and tough spots with minimal care. A longtime favorite at Barnsley Gardens, it's a passalong plant worth seeking out for its toughness and charm.
