Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge with cotyledons (seed leaves), developing the first true heart-shaped leaves

Keep soil moist and warm (70-75°F). Provide bright indirect light. Thin seedlings to prevent crowding. Mist lightly to maintain humidity.

2

Vegetative

4-6 weeks

Plant produces multiple stems with heart-shaped leaves and climbing tendrils. Growth is vigorous and foliage becomes fuller.

Provide a trellis or support structure for climbing. Pinch tips early to encourage branching. Maintain consistent moisture and humidity. Fertilize every 2-3 weeks with diluted balanced fertilizer.

3

Flowering

6-10 weeks or until frost/end of growing season

Small, tubular purple-red flowers appear in clusters along the stems. Flowers emit a sweet, distinctive fragrance, especially in evening.

Continue regular watering and feeding to support continuous blooms. Remove spent flowers to encourage more blooming. Ensure adequate air circulation to prevent fungal issues.

4

Seed Development

4-6 weeks after flowering

If flowers are not removed, small seed capsules develop. Seeds mature inside papery pod-like structures.

Allow some flowers to fade if you want to collect seeds for next year. Leave pods on plant until dry and papery before harvesting.

5

Dormancy/Winter

3-4 months

In zones below 10, plant dies back after frost or can be brought indoors as a houseplant with reduced growth

If growing indoors, reduce watering and provide cooler temperatures (50-60°F). Maintain humidity with occasional misting. Resume normal care in spring.
