Lo & Behold® Blue Chip Butterfly Bush

Lo & Behold® ‘Blue Chip’ is a compact butterfly bush with blue-purple flowers and foliage described as green by Proven Winners and gray-green in the plant patent. The breeder lists a mature height and spread of 24–30 inches; the patent reports two-year-old trial plants at 0.46 metres tall and 1.4 metres wide, a notably broader spread.

The compact, multi-branched plant forms a mounded, spreading outline. Patent observations describe low fertility and reduced seed set; they do not establish absolute sterility. ## Garden use Use this dwarf selection in a sunny border, container, or mass planting. Proven Winners lists butterflies and hummingbirds among its visitors and says routine deadheading is unnecessary. Allow room for horizontal growth, which can vary with site and pruning. ## Siting and soil Grow in full sun with good drainage. Proven Winners lists average water needs and USDA zones 5–9; the patent describes moderate moisture. Water regularly while the roots establish, then adjust to rainfall and soil conditions. ## Maintenance The plant flowers on new wood. The patent recommends severe late-winter or early-spring pruning before bud break for profuse flowering, while Proven Winners says pruning is generally unnecessary but spring trimming is possible. Wait for new growth after winter before removing damaged stems, and avoid fall pruning.
