Texas FFA Nursery Landscape Practice Exam

In what arrangement are shrubs typically planted in small groups in the landscape?

1. Groups of 4

2. Odd numbered groups (i.e. 3,5,7)

3. Even numbered groups (2,4,6)

4. Groups of 2

The correct answer is: Odd numbered groups (i.e. 3,5,7)

Shrubs are typically planted in odd numbered groups, such as 3, 5, or 7, because this arrangement creates a more natural and aesthetically pleasing look in the landscape. Odd numbered groupings help to break symmetry, which can make a planting appear more dynamic and visually interesting. This asymmetry mimics nature more closely, as plants don't often grow in even patterns in the wild. Additionally, odd groups can provide better visual balance when viewed from different angles and can enhance the overall composition of the landscape design. Even numbered groups and pairs may lead to a more rigid and formal appearance, which can feel less organic. Therefore, through odd-number arrangements, landscape designers aim to achieve a more harmonious integration of plantings into the surrounding environment, contributing to the overall appeal of the space.
