The Blue Morning Glory is a sub-species of Morning Glories that lignifies at the base, which allows it to be perennial in milder climates and with some protection during winter. Its growth is vigorous, therefore it's suitable for pergolas, high walls and facades up to 6 meters in height. It's also ideal to hide downpipes. Unlike other morning glories, the flowers can last till late evening, but the plant will only bloom well in warm summers. The highly decorative foliage can compensate for a lost flowering season.

The blue morning glories prefer a warm, sunny to semi-shady location, calcareous (basic) and permeable humose but lean garden soil, no standing water, and no nitrogen fertilizers. It must be protected in winter with a cover for the first few years for it to be perennial. It's suitable for bucket culture. Available as seeds or pre-cultivated potted plants from spring on.
Annual twining vine that can be perennial in milder climates, originally from tropical America, widely found growing on fences and hedges in the Mediterranean area. If planted out early, the young shoots must be protected or covered in colder nights in March and May. This Morning Glory can grow up to 6 meters in height. Its foliage is decorative, dark green and will last until the first frost. The buds are long and spirally twisted. The flowers last one day only and fade in the evening. Flowering time from is July to October, but only in warm summers: bad weather might prevent bloolming. The base of the plant gets woody and the plant can be perennial if protected or wintered in a pot or bucket. Cut the stem down to 10 cm above the ground in late autumn or spring. If planted in a pot, store the plant at 5 - 10 degrees. After wintering the Morning Glory will flower later, only after the soil is consistently warm. Toxic seeds.
