Description

Calystegia subacaulis is a more or less hairy, perennial plant that forms a rhizome or a woody caudex as Überdauerungsorgan. The stems are prostrate or ascending, and are 2-20 cm long. The leaf blade has a length of 3 to 4 cm, more or less triangular- shaped spear and occasionally covered with small, backward -looking cloth. Forward the leaves are pointed or rounded, the base is tapered.

The inflorescence stems are up to 3.3 cm long and thus are not above the surrounding foliage leaves out. The bracts are 7-17 mm long, 4-9 mm wide, broadly ovate to lanceolate or elongated. They sit just below the calyx and then include it. The sepals are 10 to 13 mm long. The crown is white or off-white, often tinged purple at the central veins of the petals. It is 33-62 mm long.
