Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with first true leaves emerging; delicate appearance with thin stems.

Keep soil consistently moist but not waterlogged. Provide bright, indirect light. Thin seedlings to appropriate spacing.

2

Vegetative Growth

6-8 weeks

Rapid vine growth with heart-shaped leaves developing along extending stems; no flowers yet.

Provide sturdy support structure. Water regularly and fertilize monthly with balanced fertilizer. Prune to shape if desired.

3

Flowering

3-4 months (or longer in tropical climates)

Abundant clusters of delicate coral-pink or red papery flowers appearing along vine terminals and leaf axils.

Maintain consistent watering and fertilize every 3-4 weeks with phosphorus-rich fertilizer to encourage more blooms. Deadhead spent flowers for continuous flowering.

4

Fruit Development

4-6 weeks

Small papery seed pods forming where flowers were; pods contain winged seeds.

Allow some flowers to develop seed if you want self-seeding. Otherwise, continue deadheading for more flowering.

5

Dormancy (Winter)

2-3 months

In cooler zones, vine may lose leaves and enter dormancy; in tropical regions, growth slows.

Reduce watering significantly. In zones 9-10, provide frost protection or cut back severely. Prune dead growth in spring.

Pollinator Support

Wildlife

The abundant flowers attract butterflies, hummingbirds, and bees, making it a valuable plant for pollinator gardens. It provides nectar throughout the warm growing season. [source]
