Seedling
3-4 weeksTiny seedlings with first true leaves emerging; very delicate with thin stems
Keep soil warm (70-75°F) and consistently moist. Provide bright, indirect light. Use seed-starting mix and maintain high humidity
Young Vine
4-8 weeksRapid stem growth with increasingly larger leaves; plant begins to develop climbing habit
Provide sturdy support structure early. Begin gentle fertilizing with balanced formula every 2 weeks. Ensure adequate light
Vegetative Growth
8-12 weeksVigorous vine development with many branches and full foliage; no flowers yet or minimal early blooms
Train vine onto support structure. Prune to encourage bushiness and branching. Fertilize monthly with balanced or slightly higher nitrogen formula
Flowering
8-16 weeksProduction of fragrant white trumpet-shaped flowers; clusters of blooms along the vine
Switch to higher phosphorus fertilizer to encourage more blooms. Maintain consistent watering. Deadhead spent flowers to promote continuous blooming
Dormancy
3-4 monthsIn fall and winter, deciduous varieties drop leaves; semi-evergreens retain sparse foliage. Flowering slows or stops
Reduce watering significantly. Stop fertilizing. In cold zones, protect with mulch or move containers indoors. Prune back by 1/3 to 1/2 in early spring

Harvest Tips
Chilean jasmine is grown for ornamental flowers, not harvested in traditional sense. Cut stems with flowers for fresh arrangements; cut just above a leaf node. For seed pods, allow flowers to fade naturally and collect seed pods when they brown and dry (typically fall). Prune in early spring to remove dead wood and shape the vine
Fun Facts
- 🌱 Chilean jasmine is not a true jasmine (Jasminum genus) but is commonly called by this name due to its similar fragrant white flowers and climbing growth habit.
- 🌱 The vine can produce fragrant flowers for 6-8 months of the year in warm climates, with peak blooming occurring in late summer through fall.
- 🌱 The plant's tuberous roots allow it to survive winters in cooler zones even if the above-ground vine dies back; it will often regrow from the roots in spring.
