Establishment
6-12 monthsYoung plant with tender shoots and developing root system; foliage is bright green and glossy
Water regularly to keep soil consistently moist but not waterlogged. Provide light shade in hot climates. Mulch around base to retain moisture and regulate soil temperature.
Vegetative Growth
1-2 yearsPlant develops strong stems and dense foliage; can reach 6-10 feet tall and wide if left unpruned
Prune to shape and encourage branching. Feed monthly with balanced or slightly phosphorus-rich fertilizer during growing season. Install supports if training as a vine.
Pre-Flowering
2-3 months (late fall to early winter)Buds form along branches; plant may appear dormant or semi-dormant in winter
Reduce watering in late fall and winter. Avoid heavy pruning during this period as it removes flower buds. A cool period (50-60°F) encourages better flowering.
Flowering
8-12 weeks (late January through April, depending on climate)Abundant bright yellow, semi-double or double trumpet flowers appear; blooms are fragrant and attract pollinators
Continue moderate watering. Deadhead spent flowers to encourage additional bloom cycles. Do not fertilize heavily during flowering as it encourages vegetative growth over flowers.
Post-Flowering & Summer Rest
5-7 months (May through November)Flowers fade; plant focuses on vegetative growth; foliage remains lush and green
Light pruning to shape after flowering is complete. Resume regular feeding. Increase watering if temperatures rise. Plant is relatively low-maintenance during this period.
