💜 GROWING GUIDE – Paulownia (Imperial Tree)

💜 Paulownia (Imperial Tree)

Ultra-fast growth and spectacular mauve flowering in spring.

The Paulownia is one of the fastest growing trees in the world, with beautiful, fragrant mauve flowers.

Full sun. Minimum 6-8 hours of direct light per day for optimal growth and good flowering.

Water regularly and generously during the growing season. Allow the soil to dry slightly between waterings. Reduce watering in winter.

Ideal temperature: 15-25°C. Hardy down to -20°C once established. Young plants are more susceptible to frost. Can overwinter outdoors in Canada.

Apply a balanced fertilizer every 3-4 weeks in spring and summer. Paulownia trees are heavy feeders due to their rapid growth.

Water young plants every spring. Paulownia trees develop a substantial root system. A large pot is recommended.

Prune severely in late winter to control growth and encourage large leaves. Tolerates drastic pruning very well.

Blooms in spring on mature trees (5-7 years old). Clusters of fragrant mauve flowers appear before the leaves.

Tropico-Québec tip: Paulownia can grow 2-3 meters per year! Prune it regularly to keep it in a pot.
