Buddleja davidii 'Mongo' = Nanho Blue


Buddleja davidii 'Mongo' is a cultivar introduced by the wholesale Monrovia Nursery, California, in 1984. The shrub was accorded the RHS Award of Garden Merit in 2002, but was placed on the Sunset List for rescission in 2010 following the release of other compact forms with a superior hue.
