FIELD ID CHARACTERISTICS:
Look for 4-petaled yellow flowers, and brown box-shaped capsules.
Description: Erect, tall herb when mature, with branches turned upward, 1 to 1.25 m tall.
Leaves: Alternate, lance-shaped to narrowly elliptic with very short petioles and smooth margins. Stems reddish, angled, and slightly winged.
Flowers/Fruit: Bright yellow, 4-petaled flowers, about 1.25 cm across. Round yellow petals often drop quickly, but 4 green sepals remain. Capsule distinct, 4-angled and box-shaped, remaining into the winter. Blooms May to October, fruiting soon after.
Habit and Range: Quite common throughout the state in open, sunny, wet or damp areas like bogs, marshes, ditches, pond margins, low areas, and openings in swamps.
COMMON CONFUSIONS:
Other erect-growing North Carolina Ludwigia species tend to have more than four petals or none at all. The similar Ludwigia decurrens (wing-leaf primrose-willow) has winged stems, the wings originating from the base of each leaf and extending down the stem. Ludwigia decurrens also has elongated, winged fruits.
