Ludwigia ovalis

Ludwigia ovalis. This plant displays small green to pinkish-orange leaves that are oval-teardrop shaped with lighter veins. Ludwigia ovalis is a stem plant that stays low and mostly upright, with a tendency to grow at a slight angle. 

It is a relatively easy plant to grow, requiring mainly medium to bright light and regular fertilisation, particularly micronutrients. CO2 will encourage more rapid, dense growth but is not required.
