Landscaping Around AC Units: Purpose and Plant Choices

The Question

Bushes around AC units are failing. Homeowner wants to replace with flowers. What’s the purpose of the bushes—soil retention, shade for efficiency, or aesthetics? Will annuals/perennials work? Suggestions for Central Florida?

Expert Response (Kathy)

Primary purpose: screening the unit, especially near front yards or entertaining areas. Shade can marginally improve efficiency but isn’t the main intent. Soil retention is rarely a factor.

Needed Information

• Exact location of the unit (sun/shade, proximity to house).
• Unit dimensions (height, width, clearance requirements).
• Airflow clearance specs from manufacturer (usually 12–24″ on all sides, 60″ above).

Plant Selection Guidelines

• Choose low-growing, heat-tolerant perennials/annuals that won’t restrict airflow.
• Avoid thorny, messy, or bee-attracting plants near service access.
• Central Florida suggestions: dwarf shrubs (e.g., ‘Schillings’ holly), ornamental grasses, lantana, pentas, salvia—all in containers or well-drained beds.
