PLANT OVERVIEW

About Hygrophila lancea 'Araguaia'

A compact hygro with fine bronze-red leaves for high-tech tanks.

Despite the 'Araguaia' name it's an Asian Hygrophila lancea, forming dense clusters of narrow leaves in bronze, copper and red under strong light and CO2. Slow for a hygro and genuinely demanding, it's a refined midground color plant.
