Hygrophila “Araguaia” is named after a river system in Brazil.
The stem becomes 10-20 cm tall and 6-15 cm wide. It has compact, tight-sitting leaves and grows branches easily. Pinching of the stems maintains a bushy look. The plant is reddish brown to purple in colour and is promoted by good growth conditions. The growth rate is average for a Hygrophila.
Difficulty: Easy. Leaves will stay much more compact with emersed growth but acclimation is fairly easy and makes a great plant in a wet media even outside of a terrarium.
