[Cultivation]
Propagate from seed.
It prefers a well-drained, well-ventilated place in partial shade.
When planting in the ground, it is best planted under deciduous trees.
For potted plants, water thoroughly after the soil has dried; for plants in the ground, rainfall is sufficient.
If basal fertilizer is applied, no further fertilizer is particularly necessary, but for potted plants, slow-release fertilizer may be placed on the soil after the buds emerge in spring and after flowering.
There are no particular pests or diseases.
