Calystegia

Family Convolvulaceae. There are 25 known species growing in the temperate zone of the Northern and Southern Hemispheres.

Perennial herbaceous plants, twining or climbing up to 4 m high. Leaves alternate, kidney-shaped, ovate or triangular with a cordate base. Flowers solitary, single and double, pink and pink-white, 4-6 cm in diameter, on long flower stalks. Fruit - a four-valved capsule.

Location: winter-hardy, undemanding, prefer open, not very wet sites.

Soil: for good flowering require loose, fertile garden soil. Drought-tolerant; do not tolerate waterlogging or high groundwater levels.

Propagation: by root suckers and seeds. Self-seeding is common in cultivation. The hairy Calystegia reproduces only vegetatively - by division in early spring. All species transplant poorly and only at the beginning of vegetative growth, as they have a deep, spreading rhizome.
