This cultivar bears purple flowers against bold light yellow and green variegated foliage making it beautiful whether flowering or not. A compact well-branching plant with a slower growth rate than is usually typical of Buddleja; B. ‘Burncross’ shows a more compact and mounding habit rather than the usual upright growth type. The variegation is stable and the plant is non-invasive as it does not spread or set seed. From Blooms of Bressingham
Unfortunately the plant in the Longstock display is weak and does reverted and set seed. This plant has now died in the collection. This cultivar will be grown in pot in 2016.
History
The natural variety of Buddleja davidii was found by Dr Rob Senior in Penzance in 2000 and propagated by him, a natural “sport” on a plant now destroyed by car park construction.
Named by Dr Senior and his brother John in memory of their father, John Leslie Senior, who introduced both of them to gardening and whose family had been born and raised (as they had been) in Burncross, a small village on the now extended northern fringe of Sheffield, Yorkshire, England.
