  1. Seasonal color in landscape design refers primarily to:

    Answer: Annual and perennial plants selected for rotating bloom periods

    Seasonal color programs use annuals, bulbs, and perennials strategically rotated or selected to maintain visual interest and bloom through multiple seasons.

  2. In landscape design, 'negative space' refers to:

    Answer: Open, unplanted areas that provide visual rest and define planted forms

    Negative space — lawn panels, open water, paving — provides visual breathing room that frames and highlights planted areas, a key principle in balanced composition.

  3. What does ADA compliance mean for commercial landscape installations in the US?

    Answer: Ensuring paths and facilities are accessible to people with disabilities

    The Americans with Disabilities Act (ADA) requires landscape paths, ramps, and facilities on commercial and public properties to meet accessibility standards for wheelchair users and others with disabilities.

  4. The Landscape Architect Licensure Examination (LARE) is required for professional licensure as a landscape architect, while CH certification is administered by which organization?

    Answer: American Horticulture Industry Association (AHIA) / PLANET

    The Certified Horticulturist (CH) credential is administered by the National Association of Landscape Professionals (NALP), formerly known as PLANET/AHIA.

  5. Which planting pattern provides the best canopy coverage for weed suppression in shrub borders?

    Answer: Triangular/staggered spacing (offset pattern)

    Triangular/staggered spacing offsets plants in adjacent rows, maximizing canopy overlap more efficiently than square or row planting and shading out weeds sooner.

  6. A plant community approach to landscape design attempts to mimic natural plant associations because:

    Answer: Plants adapted to growing together need less supplemental water, fertilizer, and pest management

    Designing with plants that naturally co-exist in the same ecological community creates self-sustaining landscapes that require far less irrigation, fertilization, and intervention.
