Habitat: Roadside ditches, pond edges
Elevation: 0–1800 m
This species has in the past been incorrectly identified as either Heteranthera reniformis (J. A. Steyermark 1963) or H. peduncularis (R. B. Kaul and C. N. Horn 1986). However, detailed study of development, floral morphology, and chromosome number revealed distinct differences (C. N. Horn 1985, 1988).
Three distinct genetic forms of this species exist, two in the flora range. Populations along the Atlantic coast have white flowers and inflorescences with most of the flowers within the spathe. Populations in the Great Plains have blue flowers and inflorescences with most flowers typically beyond the spathe. These populations have not been, nor should they be, recognized at any taxonomic level.
