About

Ludwigia arcuata is a stem plant in the family Onagraceae, native to the southeastern United States. It is characterized by a delicate form of fine, arching linear leaves, and under ample lighting with CO2 the leaves color from orange to red, lending an airy red accent to the mid and background. Among Ludwigia species its leaves are notably narrow and graceful, giving a soft impression when grown in groups. Strong lighting, CO2 injection, and iron-containing liquid fertilizer are effective for coloration and healthy growth. Growth is relatively fast, and it is easily propagated by trimming and replanting. Somewhat delicate and requiring attentive care to maintain coloration, it suits intermediate hobbyists.
