Seedling
2-3 weeksSmall plants with 2-3 true leaves and thin stems. First leaves are simple and heart-shaped.
Keep soil warm (70-75°F) and evenly moist. Provide bright light. Thin seedlings to strongest plants.
Vegetative Growth
3-4 weeksRapid vine elongation with increasingly larger heart-shaped leaves. Tendrils begin to develop for climbing.
Install support structure early. Water consistently. Apply balanced fertilizer every 2-3 weeks. Prune tips to encourage bushier growth if desired.
Budding
1-2 weeksFlower buds form in characteristic curved clusters at leaf axils. Buds begin as deep red, tightly packed form.
Continue regular watering and feeding. Ensure adequate light exposure. Do not overwater, which reduces flowering.
Flowering
4-8 weeks, repeats throughout seasonBlooms open in progression from red to orange to golden yellow. Multiple flower clusters appear simultaneously, creating striking color combinations.
Maintain consistent moisture. Deadhead spent flowers to encourage continued blooming. Support heavy vine growth with sturdy trellis.
Seed Development & Decline
Until first frost or end of seasonIf flowers are not deadheaded, seedpods form and mature. Vine growth may slow as energy goes to seed production. Plants decline with frost.
Collect seeds before first frost if desired. Allow to fully mature on vine. In warm zones, may continue blooming through winter.
