Designing with texture in the garden


 
A garden that connects with our senses through water seems more exciting, complete and memorable.
The well-designed landscape has several key attributes. The foremost is that the plant materials and hard landscape features are all carefully composed to enhance the enjoyment of the space. The landscape acts as the backdrop to the wide range of activities taking place in a space. The designer purposefully selects and places materials to create a harmony of colours, shapes and textures for maximum visual impact.

 

Texture is by definition a quality of the surface of a material. Colour, hardiness and overall size are of secondary importance to the visual character of the material. As a result, texture is best appreciated through direct tactile experience. The growing popularity of moss gardens is a clear indication of the gardener's appreciation of fine textures, especially when coupled with natural stone or water.

Texture invites the garden visitor to touch as well as look. The irresistible velvet leaves of stachys, the satin bark of white birch, and the cat's tongue roughness of cord grass are all examples of contrasting textures, which can be directly experienced. The successful garden designer places a variety of these tactile surfaces close to walkways and seating areas to maximize the touching opportunities for the visitor.

The garden designer must also be aware of the texture of a material throughout different seasons. For example, the fine soft foliage of artemesia, which is most evident in spring and summer, is invisible in winter. The successful designer will compensate for this seasonal variation in the overall garden plan. Feature areas will be highlighted in different parts of the garden throughout each season. The designer thinks of the garden as a theatre stage, where a spotlight moves to follow and highlight the dramatic action.

 
One way to increase the tactile qualities of a garden is by varying the types of paving on the site. Each material, be it concrete, timber, natural stone, turf or aggregate, brings to the garden its own unique textural qualities and characteristics. Simply walking on such materials allows for them to be experienced as effectively as touching them with the hand.

 

Texture relies on contrast for effect. Placing fine and coarse textured materials close to each other enhances the visual qualities of each. The climbing hydrangea on a brick wall in winter has a strong dramatic effect because the distinctive rustic bark contrasts with the smoother surface of the brick.

Texture may be further enhanced by using light and shadow to the designer's advantage. For example, the same foliage combinations that give a uniform texture to a planting bed during the day can be transformed into a dramatic backdrop with the addition of decorative accent lighting. Landscape lighting should be limited to one light per feature and if possible, be set at an oblique angle to the object to increase the perception of the depth of the object.

The easiest way to assess the amount of contrast in the texture of the garden is to imagine a black and white photo of the area. The removal of colour helps to focus attention on the size and shape of the foliage and woody components beyond the appeal of their overall form and colour.

Plant textures to consider when planning a garden
The following plants will provide a range of textural qualities in any landscape.

Texture Example
Velvety Stachys (lamb's ears), Lychnis (campion)
Smooth Sempervivum (hen and chicks), Mahonia (grape holly)
Fine Chamaecyparis (false-cypress), Pinus strobus (white pine)
Rough Hydrangea (oak-leaved or climbing), Euonymus alata (burning bush)
Rugged Yucca (Adam's needle), Stipa (cord grass)
Quilted Hosta sieboldiana, Hamamelis virginiana (witch hazel)
Coarse Ricinus communis (castor bean plant), Catalpa (umbrella tree), Acanthus (bear's breeches)

Different hard and soft textures, when combined imaginatively and judiciously, will transform an ordinary landscape into a much-appreciated thing of beauty.
