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.

Plant type: flowering

Watch for — Poor or sparse flowering: Most often from inadequate sun or no annual prune. Plant in full sun and cut back hard in early spring to force flowering new wood.

The reasons butterfly bush 'pink delight' isn't blooming

Almost every non-blooming butterfly bush 'pink delight' traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding butterfly bush 'pink delight' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get butterfly bush 'pink delight' to flower

Maximise sun. Give butterfly bush 'pink delight' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for butterfly bush 'pink delight' and get the feeding right with the butterfly bush 'pink delight' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Butterfly Bush 'Pink Delight' flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.
