Developed by Dennis Werner at NC State University and marketed by Spring Meadow as part of the Lo & Behold® series. From patent application (08/23/2007):
The new and distinct variety of butterfly bush resulted from a formal breeding program established by the inventors in Raleigh, N.C. United States. One of the objectives of the breeding program was to develop a compact, spreading Buddleja with blue flower color. 'Blue Chip' originated as a third generation descendant from a hand pollinated cross of 'Honeycomb' × ('Nanho Purple' × Buddleja lindleyana) made in 2001. 'Honeycomb' (unpatented) was released in 1997, and is described as a hybrid of Buddleja davidii and Buddleja globosa. 'Nanho Purple' (unpatented) is a semi-compact selection of Buddleja davidii var. nanhoensis. Buddleja lindleyana is a species native to China.

I saw plants at the JC Raulston Arboretum in June 2011. They were nice enough but not stunning. Perhaps better later in the summer when there are more flowers. Not spectacular enough to warrant the expense (at this point usually 2x the price of other cultivars) so I took it off my 'Get' list. Not sufficiently unusual. They looked much nicer at Hillier in England in September, perhaps because it is not so hot?
