A species of the better known morning glory genus, this dwarf morning glory is not a climber, rather a mounding plant native to southern Mediterranean regions, where it acts as perennial.

As a garden plant, it is grown as an annual.

Flowers look like trumpets, about one to two inches wide, with a yellow throat, a band of white and a band of bright, saturated color.

They can be pink, blue, purple, violet and burgundy. Flowers stay open all day.

They grow best on average to poor soil for best flowering. Rich soils hinder the production of blooms. Convolvulus prefers full sun, but in areas with very hot summers, they need protection from the afternoon sun.

Average watering needs; never allow the plant to dry completely. Although reasonably drought resistant, lack of water stresses the plant and can cause disease.

Fertilize with a bloom boosting formula once every other week if growing dwarf morning glory in containers.

They can be pinched back for bushier growth and deadheaded for continuous bloom.

They are very easy to start from seed. Scarify or soak seed to soften seeds. Sow the seed five to six weeks before last frost.

Sow in individual peat pots to minimize root disturbance, about 1/8 inch deep. Keep at 70-80F, they germinate in a week.

Plant in their permanent spot after hardening off, once all danger of frost has passed and nights are warm. They can also be sown outdoors in spring, once the soil has warmed up. In warmer zones, they can be sown in early fall.

They can also be purchased as starter plants, but they don't transplant very well. Seed can be collected and saved.

They are not likely to develop disease or pest problems. Mildew can happen in humid climates. Spray with fungicide if it appears. Water regularly.
