Piedmont primrose willow

Description

Ludwigia arcuata is a delicate-looking plant species native to the southeastern United States, where it grows along rivers and pond edges. It can be found in boggy areas and has a creeping or submersed form that resembles Didiplis diandra. The emersed flowering plants can be distinguished from Ludwigia brevipes by their hairy stems, longer pedicels, bright yellow petals, and obovate shape. L. arcuata is a reddish, ramifying stem plant requiring sufficient light and an ample nutrient supply for successful cultivation. Micronutrients help preserve the reddish coloration of the shoot tips and leaf undersides. This plant can also be cultivated emersed in wet loam under bright lights. Its yellow flowers have four large petals. Propagation is easy, involving cutting lateral shoots or top shoots and replanting them. Due to its delicate structure, L. arcuata should be planted in groups of at least six stems for a striking appearance.
