Catalpa erubescens 'Purpurea' Tree

Purple Indian Bean Trees
  • £69.99 (ex VAT)
Loading...

This marvelous tree produces large, heart-shaped leaves which, when young, are a deep glossy purple, turning to shades of dark-green and chocolatey-purple as they mature. Unlike some other catalpa varieties, erubescens ‘Purpurea’ produces its foxglove-like flowers even at a young age. The creamy white flowers feature purple and orange markings and are followed by long seed pods.

A small deciduous tree, Catalpa erubescens ‘Purpurea’ has a slightly spreading form and will grow to 6 x 5 metres in 20 years. If coppiced it will stay even smaller, producing even larger leaves. Best positioned in a sheltered situation with full sun, this tree will tolerate most soils except wet sites. This purple leaved Indian Bean tree is a fantastic choice for creating bold contrast in the garden.

Planting Advice for Catalpa erubescens Purpurea Trees

Our pot grown Purple Indian Bean trees can be planted at any time of the year. Start by removing all weeds and grass within a metre of your intended planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help your tree establish more effectively, especially if you have poor soil, we advise sprinkling root grow in the hole.

Take the pot off and gently loosen the roots, then place into the planting hole. Mix 50% of the original soil with 50% compost, then fill in the hole and firm around gently, making sure not to bank the soil up around the collar of the tree. We recommend using a stake and tie kit and, if your area is prone to rabbits, a rabbit guard too. For further information, visit our help and advice section.

Aftercare of Catalpa erubescens Purpurea Trees

If you’re planting in spring, summer or dry weather, water well and regularly for the first few months. Make sure to keep an eye on young Purple Indian Bean trees and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We stock a range of irrigation kits, suitable for a variety of planting schemes.

Once planted, it is important to keep the area free of competing weeds and grass for the first couple of growing seasons.

Pruning Advice for Catalpa erubescens Purpurea Trees

Purple hybrid Catalpa trees do not require too much regular pruning. Removing any weak or wayward branches will help to tidy up the frame, whilst pruning lower branches will aid in raising the canopy. Although it is not necessary, Indian bean trees take well to hard pruning. If you wish to, you can hard prune in autumn to winter which will encourage fresh, fast growth in spring. This is great if you inherit an established catalpa tree that has not been well looked after.
