Corydalis ‘Canary Feathers’
Talk about flower-power! This, our showiest and most vigorous, heat-tolerant Corydalis introduced to date, is a blooming machine in pots or in the garden. Baking hot Dallas Arboretum has given this plant their seal of approval. This hybrid is tolerant of partial sun and is a great highlight in shady spots where it combines well with our silver-leaved Heuchera and Pulmonaria. This fantastic container plant blooms so long that early frosts can cut its life short, so some protection may be needed. Prefers moist, well-drained soils.
