[Overview]
A perennial 0.8–1.5 m tall, found in sunny grasslands.
It is thought to have originated from a cross between Yama-hiyodoribana and Hiyodoribana.
The stem is erect, branches in the upper part, and is sparsely hairy in the upper part.
The leaves are opposite, 7–17 cm long and 2.5–5 cm wide, and are usually deeply 3-lobed, with the lobes further coarsely divided.
The margins of the lobes have notched serrations.
The upper surface of the leaves is hairy near the margin, and the underside is sparsely hairy along the veins and has no glandular dots.
Sometimes the leaves are not divided and only have notched serrations.
The petiole is 0.5–2 cm long.
White to pale purple flower heads are borne in corymbs at the top of the stem.
The flower heads consist only of tubular flowers, and the pistils protrude from the flowers.
The fruit is an achene with a white pappus.
