A tender perennial that is winter hardy to USDA Zones 9 to 11. In the St. Louis area, it is grown as an annual in hanging baskets and containers or in the ground as a bedding plant or ground cover. Starter plants are often available from local nurseries in cell packs in spring. Cuttings may be taken from established plants in summer for overwintering indoors in bright but cool locations with reduced watering.
‘Hawaiian Blue Eyes’ is a popular cultivar that features slightly bell-shaped, blue morning glories (to 1” diameter) that freely bloom throughout the growing season on stems clad with oblanceolate, hairy, silvery-green leaves (to 1” long). Flowers usually close up at night and on cloudy days. Believed to be a hybrid with Evolvulus glomeratus as one of the parents or maybe a cultivar of E. glomeratus.
No known serious insect or disease problems.
Hanging baskets, containers, small area ground cover or trailing over stone walls.
