Hairy Calystegia

Family Convolvulaceae. Native to the Altai, the Sayan Mountains, and the southern Far East. Found on dry meadows, rocky slopes, in shrub thickets, occasionally in fields as a weed.

Perennial. Plant densely hairy. Rhizome long, cord-like. Stems up to 80 cm long, in the lower part thick, straight, often prostrate, in the upper part weakly twining. Leaves petiolate, oblong or broadly lanceolate, shortly acuminate, at the base flat-truncate, with small lateral lobes. Flower stalks axillary, usually shorter than the leaves, single-flowered. Bracts 1.5-2 cm long, ovate, obtuse. Flowers 4-6 cm long. Sepals ovate-lanceolate, acute, 1-1.5 cm long. Corolla pink, 3-4 times shorter than the calyx. Flowers abundantly in June–July. In cultivation since 1844. Winter-hardy without protection.
