    • RHS Level 2 Certificate Soft Landscaping: function and plant type choices
    • Learning objectives2.1 Describe how elements of soft landscaping should be selected and used to ensure that a design is cohesive.2.2 Lawns - state the use of a lawn in a garden design2.3 Name appropriate grass species for the following types of lawn: hard wearing utility; high quality ornamental; shade tolerant.2.4 Trees and hedges - state the uses of trees and hedges in a garden design [shade, vertical interest, windbreak, shelter belt, seasonal interest]2.5 State the purpose and use of shrubs in garden design2.6. State the purpose and use of herbaceous perennials in garden design2.7 State the purpose and describe the use of biennials in garden design
    • Soft Landscaping The term refers to the plants and living elements of the garden. Chosen to suit the design and the conditions. There are so many ornamental plants that it is better to decide on the design and effect required and then decide on the plants that produce it best in the conditions that apply.
    • Soft landscaping considerations Plants have colour, volume, form, line and texture. All of these may change over the seasons – so these variations need to work with the design. Repeated combinations of plants can be used to give rhythm and unity to a design. Limited palettes of genera, colours, shapes etc can simplify a planting design. Chose the effect required, then look for the plants that deliver it.
    • Soft landscaping - horizontals Easy to overlook but the horizontal plane links the design. Grass – as a lawn or rough cut is the cheapest and can be very effective. Low ground cover planting can also link design elements, for example under trees. Plants often grown as climbers, eg Hedera can also be used in this way.
    • Grass Provides a linking horizontal. Restful natural colour that goes well with most planting and hard landscaping. Need not be a mown lawn; use of rough grass either as a low maintenance planting area (bulbs and wildflowers) or to control movement. Variable height in cuts on lawns can create patterns and textures – not just stripes!
    • Verticals - Trees and Hedges Can be used to provide focal points, to create a journey or control movement. Hedges can define boundaries or divide space. Permanent structure visible all year round though the appearance may change. Provide the ‘bones’ of the garden. Provide shade, both as a planting zone and for seating etc. Can create a windbreak – microclimate for plants and comfort for people.
    • Verticals - shrubs Provide permanent structure, can be used to control movement or direct sight lines. Can provide year round interest. Either as specimens, in shrub borders or in mixed borders. Can also create a windbreak, define a boundary etc.
    • Verticals - Herbaceous perennials Die back to the ground each winter and grow again late spring. Therefore if cleared as is traditional in autumn the site can lack interest until the next summer. Use in Prairie planting, cottage style planting or mixed borders avoids this issue. Enormous range of heights, colours and forms to suit any design purpose provided the lifecycle is taken into account.
    • Verticals - biennials Germinate and grow in one season, overwinter and then flower, set seed and die in the next year. Means that they take up space whilst growing without adding to the effect that year. Can grow in nursery beds and transplant or in informal planting where the successors can self seed Note that some short lived perennials are usually grown as biennials
