What are the horticulural aspects of Lonicera periclymenum ?

Lonicera periclymenum grow best in partial shade to full sun, with average temperatures ranging from 35°F to 90°F (2°C to 32°C). It thrives in well-drained soil with a pH between 6.0 and 7.0, and can tolerate a range of soil types.

Lonicera periclymenum prefers to be planted in the spring or fall, when the weather is cooler. It is typically grown as a shrub, but can be pruned to maintain a desired shape or size. Planting multiple honeysuckle shrubs can help to create a dense hedge or screen.

Honeysuckle flowers are typically harvested in the summer, when they are fully open. The flowers are best picked in the morning, when the dew is still present, and should be used immediately. Vines can be harvested for their berries, which ripen in late summer to early fall.

Honeysuckle is susceptible to several pests and diseases, including Japanese beetles, aphids, and spider mites.
