Tie Vine is a native herbaceous perennial vine in the Morning-Glory family. It can be found in the lower two-thirds of Alabama. Tie Vine occurs on roadsides, along railroad tracks, in fields, in disturbed woodlands, and along streams. It is a weak perennial from a branching network of roots with small, elongate tuber-like thickenings. The twining stems are green or purplish in color and pubescent. Leaves are alternate, petiolate, cordate or 3 to 5-lobed, and glabrous or pubescent with scattered hairs. Flowers are produced in axillary 1-5 flowered cymes. The sepals are subequal, coriaceous (leathery), ovate-lanceolate in outline, and pubescent towards the base or glabrous. Flowers are funnelform and pink-purple with a darker throat or rarely all white in color. The flowers open overnight and wither by mid-morning except on cloudy days. The fruit is a 2-6 seeded papery capsule. Tie Vine is available as seed from some wildflower seed companies. It prefers a sunny site with a trellis or other structure to climb on. It tends to be weedy and will spread by root sprouts and seed. Tie Vine is a serious pest in some row crops such as cotton. Tie Vine hybridizes with the Small White Morning Glory (Ipomoea lacunosa Linnaeus) to form Ipomoea ×leucantha Jacquin. The hybrid is intermediate in most characteristics between the parents.—A.
