|A typical beach plant,
Calystegia soldanella, is a perennial vine herb in sandy soil on
the seashore and propagates itself by extending its white rhizomes
long underground. Stems crawl on the ground and wind themselves
around something if there is. Leaves are alternate, 2-4cm long,
3-5cm wide, in the shape of a kidney-circular, with deep, thick, and
glossy bases. Axils emerge peduncles and set light red flowers at
the tips. Bloom time: May-June.
