Lagenaria siceraria
A vigorous climbing or trailing vine featuring large, rounded leaves, white nocturnal flowers, and distinctively shaped hard-shelled fruits that often resemble a dumbbell or bottle.
- Light
- Full sun, requiring 6 to 8 hours of direct sunlight daily
- Water
- Moderate to high watering frequency; keep soil consistently moist during the growing phase but avoid waterlogged conditions
- Growth
- Fast-growing annual or perennial climbing vine that can reach lengths of 15 feet or more, utilizing tendrils to ascend structures or spreading extensively across the ground
Care instructions
Provide full sun exposure for at least six hours daily. Grow in fertile, well-draining soil with a neutral pH. Water consistently to maintain even moisture, allowing the top layer of soil to dry between waterings. Apply a balanced liquid fertilizer during the growing season to support strong vine development.
