    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for evidence that clearly distinguishes between the structural and seasonal roles of trees, shrubs, and herbaceous plants within a proposed design.
    • Assess the ability to identify and describe at least three ornamental features (e.g., flower colour, leaf texture, bark interest) for a given selection of common garden plants.
    • Expect accurate specification of plant material, including correct botanical names, quantities, and sizes, as appropriate to the design brief.
    • Award credit for accurate use of binomial nomenclature, with genus capitalized and species lowercase, in plant lists and design documentation.
    • Evidence must demonstrate selection of trees, shrubs, and herbaceous plants appropriate to given site conditions, design theme, and functional requirements.
    • Learners should provide detailed descriptions of ornamental features (e.g., flower color, foliage texture, seasonal interest) and justify plant choices for year-round appeal.
    • Credit when hedges are correctly specified with species suitable for purpose (screening, boundaries, ornamental) and proper spacing and maintenance considerations.
    • Assessors should see a comprehensive bulb planting plan that includes species/varieties for different seasons, considering naturalizing, containers, and bedding schemes.
    • For plant specification, look for a complete planting schedule listing quantities, sizes, forms (e.g., bare root, container), and suppliers, aligned with a planting plan.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always cross-reference plant selections with their mature height and spread to demonstrate a realistic and sustainable planting plan.
    • 💡Include clear, annotated photographs or illustrations in your portfolio to evidence your understanding of ornamental features.
    • 💡When specifying plant material, use a consistent format (botanical name, common name, quantity, size, and any special requirements) to showcase professional practice.
    • 💡Always double-check plant names against a reputable source like the RHS Plant Finder; correct nomenclature is a fundamental aspect of professional practice.
    • 💡In design tasks, create a planting palette matrix linking each plant to its ornamental features, site requirements, and role in the scheme to demonstrate thorough knowledge.
    • 💡When specifying hedges, include a maintenance schedule and note any legal considerations (e.g., boundary hedges). This shows applied understanding.
    • 💡For bulb displays, use a seasonal chart to plan successional planting; this visually demonstrates your competence in achieving year-round interest.
    • 💡Demonstrate Understanding of the Brief: Always refer back to the project brief or client requirements in your design proposals. Show how your choices for plants, materials, and layout directly address the specified needs and constraints.
    • 💡Clearly Annotate Your Designs: Whether it's a sketch or a plan, ensure all elements are clearly labelled, materials are specified, and plant names (even common ones at Level 1) are included. This demonstrates your knowledge and helps the examiner follow your thought process.
    • 💡Justify Your Choices: Don't just state what you've included; explain *why* you've chosen a particular plant for that location, a specific material for a path, or a certain layout. Link your justifications back to design principles, site analysis, or client needs.

    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing ornamental features with functional uses, such as stating that a plant provides shade as its main ornamental value.
    • Incorrectly assuming all herbaceous plants die back completely in winter without recognising evergreen or semi-evergreen herbaceous varieties.
    • Overlooking mature sizes when specifying plants, leading to over-planting or inappropriate spacing in the design.
    • Confusing common names with scientific names, or incorrectly formatting binomial names (e.g., not italicizing or capitalizing species) in assignments.
    • Selecting plants based solely on appearance without considering soil type, aspect, or hardiness, leading to unsuitable recommendations.
    • Overlooking the mature size of plants, resulting in overcrowding or inappropriate placement near structures.
    • Using hedges that are not suited to the intended function (e.g., slow-growing species for immediate privacy) or ignoring maintenance requirements.
    • Failing to account for bulb flowering times, leaving gaps in seasonal displays or planting bulbs too shallow/deep.
    • Providing incomplete plant specifications, such as omitting pot sizes, delivery timings, or substituting species without noting.
    • Misconception: "Garden design is just about choosing pretty plants." Correction: While plant selection is vital, garden design is a holistic process that equally prioritises functionality, site analysis, hard landscaping, and applying design principles to create a cohesive and usable space. Ignoring these elements leads to impractical or unsustainable designs.
    • Misconception: "You need to be a brilliant artist to do garden design." Correction: While artistic flair is a bonus, Level 1 focuses on clear communication through basic sketches and plans, not fine art. The ability to accurately represent your ideas, label features, and show scale is far more important than producing highly detailed artistic drawings.
    • Misconception: "All gardens need a lawn." Correction: Lawns are a traditional feature but not always necessary or appropriate. Modern garden design often explores alternatives like permeable paving, wild flower meadows, or gravel gardens, especially in smaller spaces or for low-maintenance requirements.
