Narrow Leaf Giant Temple - Hygrophila corymbosa 'siamensis'

Hygrophila corymbosa is popular and has several cultivated varieties but all have similar appearances and requirements. This plant has a thick twig-like stem from which grows long leaves. Some varieties have broader leaves while others are more narrow. It can be pruned from the top, especially if it is allowed to grow out of the water as this may cause the lower leaves to drop off. It also tends to prefer higher flow and moderate to very high light.

Bunched plants are typically sold as cuttings that are bound together with a metal plant weight or rubber bands. These individual stalks can be planted by inserting the end of the stalk into the substrate, either individually or - with some plants - in groupings of several stalks. Most bunch plants do not have roots but may grow roots in time. They can be easily pruned by trimming the stalk at the desired height. The trimmings can then be planted as well if desired. Some bunched plants do not need to be planted and may be allowed to float on the water's surface.
