Hygrophila corymbosa 'Thailand'
'Thailand' has the thinnest leaves of all three varieties of H. corymbosa. Under strong lighting the leaves turn a reddish-brown; under normal lighting they are a medium to light green. Open aquaria enable the plants to produce small, lilac flowers. Emersed shoots typically display hairs on the stems, and are generally firmer and more solid. Varieties of Hygrophila are also ideal for paludaria and humid terrariums.
