1-2 yearsRapid climbing growth with lush green foliage; vine extends significantly along support structure
Guide stems along support; remove lower leaves to encourage upward growth; prune lightly to shape; maintain consistent moisture and fertility
Pre-flowering
2-4 weeks before floweringVine reaches mature size with well-established branching; flower buds begin forming in late autumn
Minimal pruning; avoid heavy nitrogen fertilizer; reduce watering slightly; ensure support structure can handle mature plant weight
Flowering
8-12 weeks (typically December-March in Northern Hemisphere)Abundant nodding bell-shaped cream flowers with purple stamens appear in clusters; blooms persist for several weeks
Maintain moderate moisture; do not prune during flowering; enjoy extended winter and early spring display; deadhead spent flowers if desired to neaten appearance
