Corydalis aurea Willd.

Best Life Stage for Proper Identification [-]
Golden corydalis is best identified when in flower.

Similar Species [-]
Corydalis flavula, the only other yellow-flowered corydalis in New York, has similar leaves but its flowers are about half the size of those of C. aurea, and have a prominent crest or wing on the outer petal not found in golden corydalis. Corydalis flavula also is typically found in wetter and/or less open sites than C. aurea.

Golden corydalis may grow alongside Corydalis sempervirens (Rock Harlequin, or Pale Corydalis), which has pink to purplish flowers. In vegetative form C. aurea differs from C. sempervirens by its less glacous leaves and stems, more sprawling habit, and more finely dissected leaves.

The Best Time to See
Golden corydalis may be found flowering from May into September; fresh flowers found in late summer may be the product of fruit from early-blooming plants of the same season. The leaves senesce but persist into flowering and fruiting. Flowering specimens are best for identification and collection purposes.
