Establishment
3-6 monthsYoung vine establishes root system with simple leaf growth; minimal above-ground growth visible.
Keep soil consistently moist but not waterlogged. Provide sturdy support structure. Protect from harsh winter winds in cooler zones.
Vegetative Growth
6-18 monthsVine develops vigorous climbing growth with glossy, ovate evergreen leaves (1-3 inches long) and increasing stem length.
Train vines onto support structure by gently tying or weaving through trellis. Prune to control shape and encourage branching. Reduce watering once established.
Pre-flowering
4-8 weeksMature vines develop flower buds along stems; compact growth along main branches with slight thickening of vine structure.
Avoid heavy pruning 6-8 weeks before flowering (late winter). Light fertilization with balanced or low-nitrogen fertilizer encourages flowers over foliage.
Flowering
4-8 weeksAbundant bright yellow, fragrant, tubular flowers (1-1.5 inches long) appear in clusters along vines; peak bloom in late winter to early spring.
Deadheading spent flowers encourages extended bloom. Maintain moderate moisture. Stake or tie vines as weight of bloom increases. Enjoy fragrance, especially in early morning.
Post-flowering
Variable; begins after flower dropFlowers fade, vines produce small seed pods (if pollinated); vine returns to vegetative growth and vine extension.
Allow seed pods to mature if desired for propagation. Resume regular maintenance pruning. Resume moderate fertilization for vigor.
