Cypress Vine, with its tiny red flowers and delicate fern-like leaves, is a marvelous thing to have on a fence. Belonging to the same genus as the morning glory, the dainty red flowers bloom in the morning. The leaves are 3-4 in long and feather-like, finely divided pinnately into threadlike segments. The scarlet red (rarely white) flowers are tubular, about 1.5 in long, and flare out at the mouth into a five-pointed star. This annual plant produces hundreds of flowers--and thousands of seeds--usually insuring its presence from year to year.
