Foxglove Tree Paulownia tomentosa fast growing ornamental tree

Foxglove Tree – Paulownia tomentosa

One of the most spectacular ornamental trees you can grow in the UK. The Foxglove Tree is a deciduous hardwood native to China and Taiwan, prized for its extraordinary spring flower display and its remarkable speed of growth.

Flowers & Foliage

Between April and May, the entire crown erupts in dramatic 20cm-long panicles of up to 30 individual foxglove-shaped flowers in soft violet-purple. Once the blooms fade, enormous tropical-looking leaves emerge to cast generous shade throughout summer. Mature trees can reach up to 15m tall with strikingly thick, grey-felted shoots.

Climate Resilience

Originating from warm regions, Paulownia tomentosa thrives in hot urban climates and tolerates prolonged heat and drought — making it one of the best trees for climate change. Its rapid growth and massive leaf canopy also make it an exceptional CO₂ absorber. Specimens can be found in parks across the UK, including Norwich.

Planting Guide

• Plant young trees after the last frost; perennial root balls can go in from March.
• Dig a planting hole 1.5× the size of the root ball.
• Improve poor soil with sand or mature compost.
• Position so the root neck sits just above the soil surface, firm down well, form a watering rim, and water generously.
• Note: As crowns and roots grow vigorously, Foxglove Trees are only suitable for containers during their first few years.

Watering & Feeding

Water regularly after planting until established. Once settled, the tree is drought-tolerant and rarely needs feeding. If soil is very poor, apply a light feed before June — avoid excess nitrogen, which can increase frost susceptibility in winter.

Pruning

Generally not required. Remove any frost-damaged shoots as needed. To raise the crown height, remove young side shoots progressively until the desired trunk height is reached. Always prune after flowering to avoid removing next season's buds.
