Berberis thunbergii ‘BONANZA GOLD ® ‘
This Japanese barberry is a relatively new plant, patented in the USA only in 1993 (PP8215). It is a cross between varieties Atropurpurea and Aurea Nana. The result is a compact, nearly thorn-free shrub, with bright yellow leaves tolerant of sun scald.
Bonanza Gold ® is a beautiful choice for borders and group plantings with its bright yellow-golden leaves and mound-forming, low habit. Its growth rate, however, is not as slow as you may have expected from a dwarf plant.
It tolerates most soil types provided it is well-drained. Fully hardy to -34�C (USDA zone 4).
