Hygrophila Araguaia, AKA Hygrophila lancea was named after the Brazilian river Araguaia in trade, however, later on, it was identified as the Asian species Hygrophila lancea. Underwater it grows lineal reddish-brown leaves with a lighter-colored central vein. Its stems have a creeping growth habit, ramify well and form low bushes. Trimming the leaves maintains the bushy form. Hygrophila lancea "Araguaia" does best in moderate to strong light with co2 or a co2 supplement. In contrast to most other Hygrophila species, it is a rather slow grower. Usually, it is sold in its emerged form and differs very much from the underwater form (see picture 3), which develops after it has been placed in the aquarium.
You are buying one bunch, approx. 3 or more stems.
Plant Weight included with all bunched plants.
Stem plants are usually cuttings of plants that normally don't come with roots. This is how stem plants are sold in the aquatic plant industry although many times my stem plants may come with roots because I have been growing them out. All stem plants come with a plant weight that holds the plant in place and is safe for your tank.
To plant just let the weight lay on your substrate and the stems will grow roots throughout your substrate. You can also plant the tips, about 1/4" in your substrate if you prefer.
