The flowers are usually solitary in the leaf axils on the upper part of the stem, white, 1–1.5 cm across.
The corolla is 7-lobed; the lobes are oblong with pointed tips, and the tips are sometimes tinged with pale red.
The fruit is a spherical capsule.

It prefers partial shade and well-drained soil.
In summer, move it to cool, airy shade.
Water thoroughly when the soil surface dries.

[Notes]
The name is said to derive from the fact that the edge of the corolla is sometimes edged in red.
