How Long Until a Cypress Vine Blooms?

Cypress vine, or Ipomoea quamoclit, is from the morning glory family and is often called star glory, cardinal climber, cypress vine, Indian pink or cypress vine morning glory. Native to tropical America, the cypress vine has naturalised in many areas of the United States, primarily in U.S. Department of Agriculture hardiness zones 6 though 10.

Plant Description

The cypress vine is a fast-growing twining vine with lacy, feather-like leaves and fragrant small red (or occasionally white in some cultivars) tubular, star-shaped flowers. The showy flowers bloom June through October and attract butterflies and hummingbirds. This tropical vine typically grows as an annual but often emerges in the spring from seeds that fall and stay in the ground through winter. Cypress vines can reach 20 feet under perfect conditions but usually grows from 6 to 10 feet long.

Treating and Starting Seeds Indoors

Sow seeds indoors six to eight weeks before last frost. Scratch or cut and then soak the cypress vine seeds in room temperature water for two to 24 hours before planting. These practices will speed up the germination process. Sow the seeds 1/4 inch deep in cell packs or small 2-inch pots. Place the seeds in a location with temperatures of 21.1 degrees Celsius. Maintain moist, but not soggy, soil until the seeds sprout in four to 21 days. Plant the transplants outdoors in the spring.

Planting Cypress Vine Seeds Outdoors

The best time to plant cypress vine seeds outside is after the last chance of frost has passed in your area. Select a location with full sun and well-draining soil. Select a planting spot near a support to allow the vine to climb on such as a trellis, arbor, fence, railing or similar structure. Clear the area of all foliage and sow the cypress vine seeds every 4 to 6 inches. Thin the seedlings to one or two plants every 12 inches.

Planting Transplants and Bloom Period

Plant the cypress vine transplants at the same depth previously planted and at a spacing of one plant every 6 to 12 inches. Provide supplemental watering in the absence of rainfall as needed to maintain moist soil throughout the growing season for optimal growth and flower production. The fast-growing cypress vine will often produce the first flowers within one month of planting the seeds. The bloom period of the vine will continue until the first frost in the fall.
