Kang Kong is a terrifically hardy perennial that will grow anywhere at anytime its growing conditions are met that is, when its hot & wet. It grows like mad in these conditions, and will meander or die back when its cold and/or dry. Seems just as happy in sun or shade.
Despite the fact that it requires very little care, Kang Kong is a highly nutritious plant with high levels of protein, calcium, iron, potassium, & vitamins A B & C.
In the tropics, it will grow all year if it has regular water, but is best planted as the wet season begins and will require no maintenance. If theres a problem with it, it can get out of control a great reason to harvest it regularly.
In cooler areas, it will die back in winter and reshoot in spring. In cold areas its growing season might be quite short.
Given its water requirements, it does best in a boggy area or on the edges of ponds. Its just as happy in shallow water as it is in wet mud. It does well in a shadehouse or hothouse and its growing period might be extended due to the extra warmth.
