Buddleja nanhoensis ‘Nanho Plum’
The Nanho race of buddlejas are naturally small growing and so are useful in tight spaces. We’ve been growing Buddleja ‘Nanho Plum’ in a corner of our double flower borders for at least 10 years. We cut it back to about 80cm during winter and it rarely grows above 180cm in height and 120cm wide. It makes willowy stems dressed in greyish, narrow willowy leaves and during summer and autumn carries rich purple plum flower heads much loved by butterflies. Tough sun lover.
