Sunjoy® Mini Saffron Barberry (Berberis thunbergii 'Kasia') is a compact, mounded deciduous shrub that delivers season-long color and structural form without the maintenance. Standing 18–24 inches tall and up to 30 inches wide, it’s an ideal fit for tight spaces, low hedges, or container use.¶The bright yellow foliage holds up exceptionally well through summer—no scorching, even in full sun. New growth brings soft orange highlights, while fall foliage shifts to vibrant red-orange. This variety is very deer-resistant, heat-tolerant, and rarely needs pruning, making it a top pick for high-traffic, low-input plantings in zones 4–8. Its neat form and reliable color make it easy to merchandise and an efficient choice for commercial and residential applications alike.
