Notes
Snail vine (Cochliasanthus caracalla) is a fragrant annual vine. It cannot take cold, and a freeze will end its season. This plant likes full sun and average moisture. Its white and lilac-purple flowers open in mid to late summer and again in early to mid autumn. The vine grows tall and spreads wide, so give it plenty of room to climb.
Pairs well with Nightshade, Angel's trumpet, Roselle, and Mexican heather.
Native range
Tropical South America.
