Bonanza Gold Dwarf Yellow Barberry

Bonanza Gold® is the trade name for Berberis thunbergii ‘Bogozam’, a compact, rounded Japanese barberry with bright yellow foliage and orange-red new shoots. The RHS describes small yellow spring flowers followed by red autumn berries, while Greenleaf Nursery lists the cultivar as a dense, low mound. ## Form and Foliage The [RHS profile](https://www.rhs.org.uk/plants/142493/berberis-thunbergii-bogozam/details) gives a mature size range of 0.5–1 metre tall and wide. [Greenleaf Nursery](https://www.greenleafnursery.com/Plant/BONANZA-GOLDR-BARBERRY) lists an 18-inch height and 36-inch spread, while the RHS describes the broader range. Both sources identify the gold foliage and compact form. The plant patent [USPP8215P](https://patents.google.com/patent/USPP8215P/en) records the cultivar name Bogozam and its Bonanza Gold trademark. ## Placement Grow in full sun or partial shade in moist but well-drained soil. Greenleaf Nursery lists USDA zone 4. The compact mound suits a border, rock garden, or mass planting; leave clearance from paths because barberry branches are spiny. ## Seasonal Interest Orange-red shoots contrast with the small bright-yellow leaves, which mature toward pale yellow-green. Yellow flowers appear in spring and red berries follow in autumn. ## Maintenance Water while the plant establishes and during prolonged dry weather. Its compact habit requires little routine pruning; remove damaged branches and shape lightly when needed.
