Which shrub can grow to approximately 10 feet and produces red/orange berries?

• A. Japanese Barberry
• B. Autumn Olive
• C. Bush Honeysuckle
• D. Amur Honeysuckle

Answer: (C)

The shrub that can grow to approximately 10 feet and produces red/orange berries is the Autumn Olive. This shrub is known for its height, typically reaching around that size, and it is distinctive for its small, edible berries which can range in color from red to orange.

Autumn Olive is particularly notable because it was introduced to North America for erosion control and as a food source for wildlife. The berries are rich in lycopene, which is a beneficial antioxidant. In addition to its potential benefits, Autumn Olive is also recognized for its ability to spread aggressively in some regions, which can lead to ecological concerns where it displaces native species.

The other shrubs listed do not exhibit the same combination of height and berry coloration. Japanese Barberry tends to be shorter, while Bush Honeysuckle and Amur Honeysuckle are also considered invasive but have different berry colors or characteristics. This unique set of traits makes Autumn Olive the right answer for this question.
