About Butterfly Bush 'Pink Delight'

Buddleja davidii 'Pink Delight' · also called Butterfly Bush · flowering

'Pink Delight' is a butterfly bush bearing exceptionally long, dense panicles of clear bright pink, fragrant flowers from midsummer to autumn. Among the showiest pink Buddleja, it draws butterflies and bees in numbers, thrives in full sun and free-draining soil, copes with drought once established, and flowers best after a hard spring prune.

Mature size: 2-3 m tall and up to 2-3 m wide unpruned; readily maintained at 1.5-2 m with yearly hard pruning.

Watch for — Powdery mildew: Whitish film on leaves in crowded, humid sites. Thin growth, improve air movement and avoid wetting the foliage.

Indoor size vs how big it gets in the wild

Butterfly Bush 'Pink Delight' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 2-3 m tall and up to 2-3 m wide unpruned. In the ground with no restriction it is a completely different plant — readily maintained at 1.5-2 m with yearly hard pruning. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Butterfly Bush 'Pink Delight' is a fast grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: low feeder. a spring compost mulch or a light balanced feed after pruning covers its needs. skip high-nitrogen fertilisers, which suppress flowering in favour of leaf.
