PLACEMENT & CULTIVATION

It will do best with full sun (though it will tolerate some light shade for part of the day). If plants become leggy, pinch back. If overwintering indoors, bring in before temperatures drop below 37°F; keep in a sunny window where the temperature is 60-70°F. Reduce watering when growing indoors.
