Sunlight
Light is an essential factor in maintaining plants. The rate of growth and length of time a plant remains active is dependent on the amount of light it receives. Light energy is used in photosynthesis, the plant's most basic metabolic process.
Soil
Loose, light, humus soil is ideal for this plant.
Temperature
For subtropical and temperate regions: Hardiness: USDA Zone 9b-11. Grows well in tropical and subtropical climate. Cold tolerance down to 30°F (-1.1°C) with protection against frost. Though the plant can tolerate a light frost for short periods of time, it is advisable to mulch the roots heavily to protect plants from freezes or bring indoors to overwinter. Water and feed sparingly during the cold months and maintain temperatures above 50°F (10°C), otherwise it will not flower.
