Sender Dwarf Morning Glory is a tropical perennial plant with showy blue flowers. Native to the tropical and subtropical Americas, now widely spread through most dry tropical and subtropical regions of the world. The plant is often harvested from the wild for local use as a medicine. It prefers sandy, open, dry grassland and rocky localities.

Description

• Evolvulus alsinoides, is a small, low-growing perennial herb in the morning-glory family (Convolvulaceae). It has slender, spreading or ascending stems covered with fine hairs and small, oval to lance-shaped leaves. Its delicate, funnel-shaped flowers are usually bright blue with pale or white centres, although colour can vary. The flowers typically open during the day and close later, and the plant may form loose mats across the ground.

Range

• Evolvulus alsinoides has a broad distribution across tropical and subtropical regions of the Americas, Africa, Asia, and Australia. Its original native range is complex because of its widespread occurrence and long history of dispersal. It is established in Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• Slender dwarf morning-glory grows in sunny or partly shaded habitats, including grasslands, open woodland, scrub, roadsides, rocky ground, and disturbed areas. It tolerates warm conditions and periods of limited moisture, often growing in well-drained soils among grasses and other low vegetation. Seasonal rainfall commonly encourages new growth and flowering.
