Needle Leaf Ludwigia
Ludwigia arcuata
Family: Onagraceae
Ludwigia Arcuata is a fine-leaved stem plant with narrow, needle-like leaves that turn deep red to orange-red under high light and iron-rich dosing, contrasting beautifully with broader-leaved green plants. It requires more light and nutrients than L. repens to achieve its signature colour. Frequent trimming promotes bushy side-shoot growth and prevents the lower stem from going bare.
