General Culture:
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.
Noteworthy Characteristics:
Native to Brazil, Evolvulus glomeratus is a non-vining morning glory-like tender perennial with trailing stems. If planted in the ground as a bedding plant, it typically forms sprawling foliage mounds to 9-18” tall. Trailing stems tend to grow somewhat horizontally to downward when planted in baskets or containers. Genus name comes from the Latin word meaning “to unroll” in reference to its non-vining habit. Flowers usually close up at night and on cloudy days. Sometimes listed synonymous with E. pilosus, which adds considerable taxonomic confusion since E. pilosus is also sometimes listed as being synonymous with E. nuttallianus (see A577), a small-flowered native North American species that is winter hardy to USDA Zone 4
Problems:
No known serious insect or disease problems.
Uses:
Hanging baskets, containers, small area ground cover or trailing over stone walls.
