Leopard plants grow in forests, valleys and grasses at low altitudes. Leopard plant likes a half shade and humid environment; Leopard plant is cold-resistant, in the area of the south of the Yangtze River can overwinter on the ground; Leopard plant is afraid of direct sunlight, has good adaptability to the soil, with fertile loose, good drainage black soil is appropriate.
In late autumn, when most of the flowers are gone, the leaves turn yellow and the branches are covered with fruit, the Leopard plant, like its distant cousin, the chrysanthemum, is in full bloom.
Leopard plants are suitable for growing in rich, loose, well-drained black soil. Cultivation can be Garden soil, leaf rot soil and river sand equal mix, as a culture soil. It is best to change the soil once a year.

Divide the plant clusters into 3 ~ 4 parts and put them into the pot respectively. Leopard plants can be cultivated in the garden, after planting management can be more extensive, winter on the ground died, the next spring will sprout leaves, appropriate shade in midsummer, control watering at the end of autumn, October into the room to keep warm, winter overwintering temperature is not less than 5℃. It is updated every 2 ~ 3 years.
