(Corydalis) Enjoy the constant flurry of color that ‘Canary Feathers’ Corydalis brings to your shade garden. The bright yellow tubular flowers of ‘Canary Feathers’ blooms from late spring through late fall and set nicely perched above the bright green foliage. Standing 9-12 inches tall, this Corydalis is one of the showiest and most vigorous to date. Grown in full shade to part shade locations, ‘Canary Feathers’ prefers moist, well drained soils. If you are looking for a long blooming perennial, this Corydalis is a great specimen for container plantings as well as in shade gardens. Hardy in zones 6-9, we do recommend protecting from frost in the cooler climates.
