Seedling
3-4 weeksSmall vine with 2-4 true leaves, developing woody stems and twining growth habit
Provide support or trellis early. Keep soil warm (70-80°F) and consistently moist. Thin seedlings to 12 inches apart.
Vegetative Growth
4-8 weeksRapid vine expansion with heart-shaped leaves covering support structure, no flowers yet
Install sturdy trellis or support structure. Monitor for mealybugs and spider mites. Ensure good air circulation. Light fertilization monthly.
Budding
2-3 weeksFlower buds appear along the vine, initially closed and pale green, gradually enlarging
Maintain consistent moisture and temperature. Avoid overfeeding nitrogen, which promotes foliage over flowers. Continue supporting growth.
Flowering
60+ days until frostLarge white trumpet flowers open in evening, typically closing by morning. Fragrant blooms appear throughout warm season.
Ensure adequate water during flowering. Deadheading spent flowers encourages new blooms. Provide consistent night temperatures above 60°F.
Seed Production
30-45 days after floweringFlowers fade and pod-like seed capsules develop if flowers are not deadheaded
Allow select flowers to mature if collecting seeds. Harvest capsules when they turn brown and dry. Store seeds in cool, dry location.

Harvest Tips
White Wings is primarily grown for ornamental flowers rather than harvest. Enjoy the blooms on the vine where they open in evening hours, typically between 6 PM and midnight. If collecting seeds, wait until flower pods turn brown and papery in fall, then dry completely before storing in paper envelopes in a cool location. For perennial growth in warm zones, cut back vines by one-third in late winter to encourage bushier growth the following season.
Fun Facts
- 🌱 The flowers of White Wings only open for one night, typically blooming between 6 PM and midnight before closing at dawn, making them a true 'moonflower'.
- 🌱 Seeds have a hard coat and benefit from scarifying (lightly sanding) or soaking in warm water for 24 hours to improve germination rates.
- 🌱 In tropical regions where it's perennial, White Wings can grow 15-20 feet or more in a single season, making it one of the fastest-growing ornamental vines.
