Yellow Corydalis

Yellow Corydalis (Corydalis lutea)

Yellow Corydalis (Corydalis lutea), also known as Yellow Fumewort or Rock Fumewort, is a hardy, shade-loving perennial prized for its profusion of bright yellow, tubular flowers and delicate, fern-like blue-green foliage. Blooming from spring through fall, this vigorous self-seeding plant provides continuous color and texture in shaded gardens, rock crevices, and borders. Its adaptability, long bloom period, and low-maintenance nature make it a standout choice for both formal and naturalized plantings.

Distinctive Features

Yellow Corydalis forms dense, mounded clumps of finely divided foliage that remain attractive throughout the growing season. Its bright yellow flowers emerge in clusters, creating a striking contrast against the lacy leaves. Unlike many shade perennials, this variety is highly floriferous, producing a near-constant display of cheerful blooms that attract pollinators and add vibrancy to shaded spaces.
