Tunera ulmifolia

Turnera ulmifolia grows erect, with dark toothed leaves and small, yellow-orange flowers, and is often found as a weed growing on roadsides. This plant is commonly misidentified with the closely related T. diffusa in horticultural commerce, causing it to be often misrepresented as “Damiana”.

The plant is widely cultivated as an ornamental in the tropics, where it often escapes from cultivation. It is reported to be invasive in several Pacific Islands. Plants can become rather leggy if they are not pruned back regularly. Plants flower and fruit all year round.
