About Buddleja 'Lo and Behold Blue Chip'

Buddleja davidii 'Tobudchip' (Blue Chip) · also called Blue Chip butterfly bush, Lo & Behold Blue Chip · flowering

'Lo and Behold Blue Chip' is a dwarf, mounding butterfly bush smothered in blue-purple flowers from summer to frost. Bred to be near-sterile and non-invasive, it suits containers and small gardens and rebllooms without deadheading. Give it full sun and free-draining soil, and tidy it with a hard spring cut for the tidiest, most floriferous habit.

Mature size: 0.6-0.9 m tall and wide (2-3 ft)

Indoor size vs how big it gets in the wild

Buddleja 'Lo and Behold Blue Chip' is a garden shrub whose final size is set more by your secateurs than by the plant — pruning, not luck, decides how big it gets. Indoors and in a pot, expect 0.6-0.9 m tall and wide (2-3 ft). A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Left unpruned it builds a woody framework that gets taller and wider every year; with annual pruning you hold it at whatever size suits the space.

Growth rate and years to mature

Buddleja 'Lo and Behold Blue Chip' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: light feeder. a spring application of balanced fertiliser or compost mulch keeps it blooming; container plants benefit from a controlled-release feed in spring. avoid excess nitrogen.

How to keep buddleja 'lo and behold blue chip' smaller

You are not stuck with the maximum size. For buddleja 'lo and behold blue chip' specifically, these are the levers, in order of impact:

Prune buddleja 'lo and behold blue chip' annually at the right time for its type — this is the primary, expected way to control its size.
Remove the oldest, thickest stems at the base each year to keep it open and within bounds.
Growing it in a large container rather than open ground naturally restricts the ultimate size.
Avoid heavy feeding if you want to limit growth — rich soil and lots of nitrogen drive bigger, faster shrubs.

The keep-it-smaller method, step by step

Prune at the right time. Time the cut to buddleja 'lo and behold blue chip''s type (after flowering for many spring shrubs, late winter for summer-flowering ones) so you do not lose the next display.
Take out the oldest stems. Remove up to a third of the oldest, thickest stems at the base to renew the shrub and contain it.
Shorten the rest. Cut the remaining stems back to an outward-facing bud at the height and width you want.
Restrict the roots. For a permanent size cap, grow it in a large container rather than open ground.
