Rarely offered in cultivation and remarkable for its large, lilac-pink, daisy-like flower heads with a yellow eye, this native of Japan and the eastern Russian islands of Kamchatka and Sakhalin is particularly attractive to butterflies and other insects. It creeps underground and slowly forms a mat of succulent, glossy, divided leaves. Flowers May to September. Height 15 cm. Sun to part shade in moisture retentive, well-draining soil.
