The Cypress vine will bear flowers every day from July until the end of September, though not as many as Ipomoea purpurea. The species is sown indoors and may be taken out-of-doors to the warmest and sunniest spot you can find by the end of May. It is also possible to buy the plant, though it is not widely available.
Ipomoea quamoclit (Cardinal Creeper or Hummingbird Vine or Star Glory) is a species of morning glory native to tropical regions of the New World from northern South America north to Mexico.
It is an annual or perennial herbaceous twining vine growing to 1-3 m tall. The leaves are 2-9 cm long, deeply lobed (nearly pinnate) with 9-19 lobes on each side of the leaf. The flowers are 3-4 cm long and 2 cm diameter, trumpet-shaped with five points, and can be red, pink or white; flowering is from early summer to late fall.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. It is a hummingbird favorite. This annual plant produces hundreds of flowers--and thousands of seeds--usually insuring its presence from year to year. Particularly in warm locations, Cypress Vine can become invasive. However, as an annual it can be controlled if unwanted plants are removed before they set seed.Start Cypress Vine flower seeds to create a beautiful climbing vine that makes the perfect concealing screen. Cypress Vines are easy and fast to grow, and they cheer up an unsightly building or climb a trellis or pergola quickly to provide a dazzling display.

Once the soil has warmed and can be loosened and weeded, sow 6 Cypress Vine flower seeds per foot. Cover with 1/8 inch garden soil, and keep them moist until germination. When seedlings emerge, thin to 9 - 12 inches apart.
