Kang Kong is a terrifically hardy perennial that will grow anywhere at anytime it’s growing conditions are met – that is, when it’s hot & wet. It grows like mad in these conditions, and will meander or die back when it’s cold and/or dry. Seems just as happy in sun or shade.
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 there’s 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 it’s growing season might be quite short.
