[Cultivation]
Propagate from seed or by cuttings.
It prefers fertile soil in a sunny, well-drained site, but grows well without being particular about soil.
It tolerates shade, but flowers poorly if the site is not sunny enough.
It is hardy and easy to grow.
Watering is unnecessary unless sunny weather continues in midsummer and the soil becomes severely dry.
Fertilizer is not particularly necessary either, but depending on growth, apply a small amount of oil cake as fertilizer in winter.
It also tolerates pruning well.
