Delta Arrowhead's flower stalk can grow up to 2' tall, with 3-8 whorls of flowers. Several whorls are branched, giving it a rather broad inflorescence. The fruiting pedicels strongly turn downward after flowering. Considered as a weed in some places, and certainly of uncertain provenance in most Atlantic Coast states.

The distribution of this species is primarily in the Mississippi drainage; occurrences east of the Appalachians may be introduced, either by humans or by waterfowl, per Weakley's Flora (2023).
