Seeds, leaves, two volunteers, and a flower
November 1, 2023
Wingleaf primrose-willow (Ludwigia decurrens) is sometimes called seedbox because of its seed pod shape, square in cross section. Other names include, wingstem water primrose, willow primrose, upright primrose-willow. The alternate leaves of Ludwigia decurrens are “decurrent” – the leaf base extends down the plant’s stem as “wings.”
This herb grows in wet or marshy areas, and is sometimes aquatic. Fragments of the plant will root in a day or two if placed in water. As you can see in the photos there are many very small seeds crammed into the plant’s numerous pods.
Primrose-willow is considered a pest in some areas but is native on the Carolina Piedmont and Coastal Plain.
We’re well into fall but our leaves have yet to peak. There are, though, a few ahead of themselves.
And finally, thanks to our volunteers for helping out here at the museum.
