Saltcedar, Russian olive, and multiflora rose are examples of which category?

• A. Native perennials
• B. Introduced perennials
• C. Summer annuals
• D. Biennials

Answer: (B)

These plants are examples of introduced perennials. They were brought from other regions and are not native to this area, yet they live for more than one growing season. Saltcedar, Russian olive, and multiflora rose all persist year after year as woody plants, rather than dying after a single season. They are not native, so they don’t fit the native perennials category, and they aren’t annuals or biennials, which would have shorter, two-year life cycles at most.
