Buddleja davidi

Sugar Plum

B. Sugar Plum  is a fairly new cultivar with long tapering clusters of pinkish red flowers with a yellow throat.  These look amazing when in full bloom, and will attract a wide range of butterflies to the garden.

As close as any Buddleja has got to being true red, B. Sugar Plum has a more compact habit than some of its red-flowered rivals. Flowers are produces in racemes up to 30cm (12”) long.
