[Overview]
A deciduous shrub.

A spherical corymb 5–9 cm across is borne at the branch tips.
The flowers are all ornamental flowers, white and 1.5–2.5 cm across, with a corolla that is unevenly 5-lobed.
[Cultivation]
Propagate by cuttings.
It grows well regardless of soil type in a sunny or partially shaded, well-drained place rich in humus.
For potted plants, water thoroughly when the soil surface dries; for plants in the ground, rainfall is sufficient unless summer brings a long spell of sunny weather and the soil becomes severely dry.
Apart from fertilizer in winter, apply a slow-release chemical fertilizer with equal amounts of the three components after flowering as a thank-you fertilizer.
Do not prune, and enjoy the natural tree shape; if you want to keep it compact, cut just above a bud as early as possible after flowering.
Poor ventilation makes powdery mildew and scale insects likely to occur, so care is needed.
