Houseplant design principles: texture

Texture adds another dimension to your houseplant displays through the visual qualities of the plants' leaves


While it can be a subtle design feature compared to the more obvious effects of colour and scale, texture offers a vital sensory element in houseplant displays. A plant's surface type determines how it interacts with light and shadow, which gives each species a unique presence. For example, velvety foliage has a soft, matte appearance while smooth, glossy leaves present a crisper, more clean-cut image.


Contrast of texture

Strong textural contrasts create drama and interest; here with various ferns
An interplay of contrasting textures can produce dynamic displays. Here the dominant, rougher, velvety texture  of the golden polypody fern (Phlebodium aureum) is sandwiched between the softer, more elegant Boston fern (Nephrolepis exultata 'Bostoniensis') and the delicate maidenhair fern (Adiantum raddianum).

Cacti and succulents come in a range of distinct forms and textures
There are many creative ways to add texture to displays, for example using moss

The greater the contrast, the greater the emphasis on each plant's individual presence. A succulent such as the plump, fleshy donkey's tail (Sedum morganianum) will accentuate the spiky prickles of a bunny ear cactus (Opuntia microdasys), for example. In the wreath, fleshy, plump succulents contrast interestingly with the intricate moss.

Bringing diverse textures together builds excitement and tension, as each texture brings a different mood to the display. The relationship between the different textures needs to be balanced, however, so it doesn't end up looking chaotic. Light and shadow should work across the design to draw the eye to the contrasts – but also to see the rhythm in them. 

Harmony of texture

Even very different plants (here mistletoe cactus and mind-your-own-business) can have similar, harmonious textures

When similar-textured plants are grouped together, the quality of light and shadow across their foliage is consistent, creating a relationship between the plants despite any other visual differences such as colour and size. This relationship unifies the display, creating a balanced whole and imparting a sense of simplicity.
 

Texture can harmonise a contrasting colour palette, linking the two purple velvet plants (Gynura) with the Echeveria (top) and Kalanchoe (bottom)

A grouping of plants that interact with light in the same way (absorbing or reflecting it, offering similar textural patterns of light and dark) will give a sense of unity that brings the composition together as a whole. Beware though, that too much repetition creates monotony. A thoughtful combination of similar textures, offset by some contrasting elements, creates lots of visual interest.  

Plants with light, feathery foliage carry less visual weight than those with denser, solid leaves; so use more in a display if you want the textures to appear balanced.
