Coefficient of Conservatism:
Coefficient of Wetness:
Swamps, streamsides, ditches, lake shores, marshy areas, thickets, ravines and wet spots in forests; often in somewhat disturbed areas, including excavations.
The flowers are usually more copiously and conspicuously spotted with deeper orange, rose, or brown dots than in I. pallida, and the long spur tends to be very strongly bent back below the sac, even a little more than 180°. Variants with yellow (sometimes very pale, almost white) flowers, without spots, or with the spots confluent, are rarely found.
The name "capensis," referring to the Cape of Good Hope, is a misnomer for this native North American species.
