Dianthus superbus longicalycinus1; a
Japanese plant that flowers in summer and
autumn. It is a member of the
dianthus family and is pink and white in colour (though some variants are scarlet or purple), with patterns similar to those of the
carnation. It is native to the Japanese town of
Hiratsuka, and serves as the emblem of
Kyoto and the Finnish
Oulonko Biological Station. Also one of "
the seven flowers of Autumn", and a popular subject in
haiku and classical poetry.
1 Its Japanese name is Nadeshiko, literally "pretty girl".
