Trade, transport, and planting this shrub is illegal in my state and two others, because it invades and destroys natural areas. I've seen state woodland turned into impenetrable thorny thickets of this species, where nothing else in the understory layer survives. It has naturalized across North America north of a line running from Georgia to Wyoming, and also in Washington.

I live in Iowa and just planted (late summer) several of these in the front of the (southeast facing) house. I'll let you all know how they fair after winter, giving a positive or negative at that time. The flowers are supposed to be the same exact color of the foliage, so they are virtually invisible-you'll have to look close to see them.

Positive

Nice, neat and easy. Takes well to shaping and is not too fussy about soil conditions. I have been growing a variety of barberry for about 8 years, and in my landscape Bonanza Gold hasn't given any indication of being invasive. The big bonus is that it is deer resistant.

In full sun, the foliage of this cultivar is a bright golden yellow. Tolerant of many soil conditions. Few disease and pest conditions. Typically has a rounded growth habit, but may need pruning to keep it's shape. Prune after flowering. Can tolerate many soil conditions.
