Dianthus superbus var. rupifragus / Iwanadeshiko イワナデシコ

Dianthus superbus var. rupifragus is a perennial inhabiting a dry, rocky area. It closely resembles another variety, that is, D. superbus var. longicalycinus. The former stems from setting flowers, not erecting, extending sideways, with leaves having a powdery tinge, and the flowers are hairy inside, with their petals being a bit more deeply split. Another difference is that it has two pairs of bracts, whereas the latter has 3 or 4 pairs. Iwao Maruyama considers this variety, rupifragus, to be a survivor of an old type in a uniquely dry, rocky area. Bloom time: May-June.
