Buddleja davidii Buzz Magenta


Butterfly bush

Fragrant flowers act as a magnet to butterflies

An excellent dwarf buddleja growing to just 1.2m (4ft) in the open ground, half that in a pot; perfect for the small garden or patio. Slender twigs carry small, narrow, grey-green leaves and the habit is bushy. Large panicles of vivid violet flowers are freely produced in late summer. The fragrance is strong and sweet and the flowering period is longer than that of most buddlejas. Very attractive to butterflies and bees, hence the name.


Plant in full sun. Ideal for dry gardens and coastal conditions. Perfect for pots.


Any well-drained soil. Thrives on poor soil and chalk. Prune hard in late winter cutting back to 60cm (2ft) or less. Deadheading as the flowers fade prolongs the flowering season. 

The perfect buddleja for the small garden

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
