Seedling
2-3 weeksTiny seedlings emerge with two small cotyledon leaves; delicate appearance with emerging true leaves
Maintain consistent moisture and warmth (65-75°F); provide bright indirect light; thin seedlings to proper spacing once they have 2-3 true leaves
Vegetative Growth
3-4 weeksRapid growth with increasingly vigorous vining habit; blue-green lobed leaves develop along extending stems; no flowers yet
Provide sturdy support structure (trellis, stakes, or arbor); pinch tips early to encourage branching; maintain consistent moisture and warmth; fertilize bi-weekly with balanced fertilizer
Flowering
8-12 weeks (continuous until frost)Small, distinctive bright canary-yellow flowers with fringed, ruffled petals appear along the vines; flowers resemble tiny canaries
Continue supporting vine growth; deadhead spent flowers to encourage continuous blooming; maintain regular watering; reduce nitrogen fertilizer to encourage more flowers over foliage
Seed Pod Development
4-6 weeks per pod cycleAfter pollination, unusual three-lobed winged seed pods develop; pods are ornamental and distinctive in appearance
Allow some pods to mature if collecting seeds; pods will dry and split open naturally when ready; continue regular care to maintain flowering on other vine sections
End of Season
Variable (frost-dependent)Vines decline with first frost; foliage blackens and plant dies back completely in frost-prone areas
Collect mature seed pods before hard frost if saving seeds; pull entire plant after frost damage; compost spent plant material; save dried seeds in cool, dry location for next season
