Buddleja davidii Buzz Sky Blue

PollinatorAward

Butterfly bush

The perfect buddleja for the small garden

An excellent dwarf buddleja growing to 1.2m (4ft) in the open ground or half that height when planted in a pot. Its compact size makes it perfect for a small garden or patio. Slender, bushy branches carry small, narrow, grey-green leaves. Large clusters of pale mauve-blue flowers are freely produced in late summer. The beautiful fragrance is strong and sweet and the flowering period is longer than that of most buddlejas. Lovely wen planted with other silver leaved shrubs.

Where?

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

How?

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.

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.
