Buddleja ‘Longstock Silver’ is possibly unique as a sterile hybrid cultivar grown entirely for its foliage. Raised by Peter Moore Chief Propagator at the Longstock Park Nursery in Hampshire England the cultivar is the result of a crossing of Buddleja crispa var. agathosma and Buddleja alternifolia ‘Argentea’ released to commerce in 2010.
