Texas FFA Nursery Landscape Practice Exam

What is a large perennial that provides a general effect of mass and grows in excess of five feet?

1. Dianthus

2. Pampas grass

3. Primrose

4. Yarrow

The correct answer is: Pampas grass

Pampas grass is recognized as a large perennial that can exceed five feet in height, making it an excellent choice for creating a mass effect in landscaping. Its tall, feathery plumes and dense growth habit contribute to its visual impact, serving as a focal point in garden design. This plant is often used for its ornamental characteristics and can thrive in various conditions, further enhancing its appeal in nursery landscapes. In contrast, the other plants mentioned do not meet the criteria of being a large perennial growing over five feet. Dianthus is typically much smaller and is often used for its flowers rather than its massing ability. Primrose, while attractive, generally does not attain the height characteristic of large perennials. Yarrow is also a smaller plant, primarily used for its clusters of flowers and hardy nature, but it does not reach the impressive height of pampas grass. Thus, pampas grass distinctly stands out as the correct answer for this question.
