Ipomoea quamoclit (Cypress Vine)

Ipomoea quamoclit, commonly known as Cypress Vine, is a fast-growing annual vine with delicate, feathery foliage and star-shaped flowers. It's easy to grow from seed and attracts hummingbirds and butterflies.

1. Seed Preparation

  • Scarification: The hard seed coat benefits from nicking with a knife or rubbing with sandpaper to speed up germination.

  • Soaking: Soak the seeds in warm water for 12–24 hours before planting.

2. When to Sow

  • Direct sowing: After the last frost, when the soil has warmed to 18–24°C (65–75°F).

  • Indoor sowing: Start seeds 4–6 weeks before the last frost in biodegradable pots to minimize transplant shock.

3. Soil & Location

  • Prefers well-draining, fertile soil with a neutral to slightly acidic pH (6.0–7.0).

  • Choose a full sun location (at least 6–8 hours of direct sunlight daily).

  • Provide a trellis, fence, or support for climbing.

4. Sowing Depth & Spacing

  • Depth: Plant seeds 6 mm (1/4 inch) deep.

  • Spacing: Space plants 15–30 cm (6–12 inches) apart.

5. Watering & Care

  • Keep soil evenly moist until germination, which takes 7–14 days.

  • Once established, Cypress Vine is drought-tolerant but benefits from occasional watering.

  • Avoid over-fertilizing, as too much nitrogen encourages foliage growth over flowers.

6. Growth & Maintenance

  • Grows rapidly, reaching 2.5–5 meters (8–15 feet) tall.

  • Deadhead flowers to encourage continuous blooming.

  • Can self-seed easily—remove unwanted seedlings if needed.
