Which of the following is NOT a listed category of ornamental plants?

• A. Bedding plants
• B. Container-grown landscape plants
• C. Flowering potted plants
• D. Groundcover vines

Answer: (D)

In ornamental horticulture, categories are often organized by how the plants are used or sold, not just by their growth habit. The listed groups cover the main ways people think about decorating spaces: bedding plants are the annuals grown for garden beds, container-grown landscape plants are shrubs or small trees sold in containers for use in landscapes, and flowering potted plants are flowering species sold as potted specimens for decorative displays.

Groundcover vines describe a growth habit and function—plants used to cover ground with a creeping or vining habit. While they are ornamental, they aren’t typically treated as a distinct listed category in the same way as bedding plants, container-grown landscape plants, or flowering potted plants. So the option describing groundcover vines isn’t part of the standard listed categories in this context.
