Lonicera japonica
A vigorous woody vine or climber with opposite, ovate green leaves and tubular, two-lipped flowers that typically open white and age to yellow, featuring prominent protruding stamens.
- Light
- Full sun to partial shade, ideally 6 or more hours of direct sunlight per day for optimal flowering
- Water
- Moderate watering needs. Allow the soil to dry slightly between waterings; once established, it tolerates dry spells quite well.
- Growth
- A perennial woody vine and twining climber that can reach lengths of 15 to 30 feet (4.5 to 9 meters) or more, with a fast growth rate and dense branching habit.
Care instructions
Provide full sun to partial shade with well-draining soil. Water regularly during establishment, but established vines show good drought tolerance. Prune annually after flowering to maintain desired shape and manage growth, as it tends to spread rapidly.
