Description

This weedy vine is native to the tropics of South Americain the morning glory family. Alhough it is an annual, it spreads quickly by self-seed propagation.  It grows rapidly reaching 10-20 feet, but is not sturdy and requires support to grow upright. The delicate, fern-like foliage recoils from direct sunlight but expands after sundown. The bright scarlet red flowers are small, blooming from early summer to fall frost and are attractive to butterflies and hummingbirds. In NC the seeds will remain in the garden and grow the following spring.

This plant grows in full sun in average soil and requires good drainage but adequate moisture. It tolerates deer, some drought, and both wet and dry soil conditions. Germination of seeds is aided by scarifying and soaking in water for 12-24 hours. It can be used on trellises and other vertical structures

Although it has naturalized in some areas of the south and west, it isn't considered a threat to native plants. It is toxic to dogs, cats and horses though.

Insects, Diseases, and Other Plant Problems:  No serious problems. Can be somewhat weedy.
