Both surfaces of the leaves have short hairs and yellow glandular dots.

[Cultivation]
Propagate by division.
It prefers sunny soil that retains water well.
If strong midsummer sunlight scorches the leaves, provide 50–60% shading.
Keep it on the moist side when watering; for potted plants, a saucer may be placed under the pot to water from below.
Fertilizer applied at planting is sufficient.
There are no particular pests or diseases.
