| cultivar = 'Pixie Blue' | origin = Unknown | image = | image_caption = | synonyms = }} The origin of the 'Pixie' series is a mystery. As the plants can grow in excess of 2 m in height, it has also been speculated that the name 'Pixie' alludes to the shape of the inflorescence, not the plant's size.[1] Buddleja davidii 'Pixie Blue' is considered by some to be a synonym of 'Dart's Papillon Blue'. Description'Pixie Blue' grows to a height of 2 m with a greater width, and is distinguished by its 15 - 20 cm long panicles of blue flowers. Owing to its narrow leaves, 'Pixie Blue' is believed by some to have 'nanhoensis' in its ancestry.[2] [3] Cultivation'Pixie Blue' has had only a limited impact in the UK and is not known in the USA. A specimen is grown as part of the NCCPG national collection held by the Longstock Park Nursery near Stockbridge. [1] SuppliersSuppliers in the UK can be located in the RHS's Plantfinder.
