Brandegee's corydalis is a rare Rocky Mountain native perennial found in cool, moist, shaded habitats such as streamsides and mountain woodlands. It produces intricate spurred flowers and finely divided foliage, requiring consistently cool temperatures and partial to full shade to perform well. This specialist plant is best suited to alpine or woodland garden settings and is not recommended for warm, dry climates.
