Grassland Style Planting with South African Indigenous Plants

Themeda triandra

Grassland Style or Meadow Style landscaping, with the predominant use of ornamental grasses in the landscape, has become increasingly popular. This is not only due to the texture, movement and interest that they add but also to the variety of contrasting seasonal foliage and color that they provide throughout the year. Grasses are generally low maintenance and they provide habitat and food for birds and other animals therefore attracting wildlife to the garden.

Grasses Increase a Site’s Biodiversity

It is encouraging to know that when introducing grasses to a landscaping project, and specifying indigenous plants in general, that the biodiversity of the site will increase. Indigenous plants attract local insects, birds and wildlife. The Grassland Biome in South Africa is increasingly under threat due to urbanization, mining and agriculture and therefore including indigenous grasses means that a small part is played in re-establishing and enhancing vegetation communities.

Applying the grassland style to south african gardens

 It is not always easy to get this style right, as the grasses often look bad in winter and need to be cut down. Adding to this, the seasonal colour planted between the grasses are often bulbs that die down completely.

But what if we reframe this challenge as an opportunity?

South Africa’s grassland biome offers a rich palette of indigenous species that are naturally adapted to seasonal rhythms, climatic conditions, and drought. By drawing inspiration from these ecosystems, we can create landscapes that are not only beautiful but ecologically resilient and low-maintenance.

Many people hope to recreate landscaping images that they find on the internet of planting styles but often these images portray plants that are not indigenous to South Africa. When looking at planting grasses in your garden please insist on using indigenous plants from South Africa and even better if they are specifically from your region.

Design Tips for grassland style planting

  • Layering: Combine grasses with flowering perennials and scattered bulbs to create visual rhythm and seasonal variety

  • Accept dormancy: Celebrate the winter phase with seasonal changes including seed heads, dry textures, and changes to foliage colour

  • Use repetition: Group plants together to enhance visual impact

south african grass species that work well for landscaping

I have listed some indigenous grasses that work well in landscaping with the help of an excellent grass book – A Practical Grass Selection Guide, South Africa (2016) by Waltman Botha and Ivan van der Wal as well as information shared with me by the late Johan Wentzel who was very passionate about Grasses and encouraged landscaping with them.

Some notable indigenous ornamental Grass species that can be used successfully in gardens include:

Andropogon eucomis (Snowflake Grass)

Aristida junciformis (Three Awn Grass)

Monocymbium ceresiiforme (Boat Grass)

Tricholaena monachne (Blue Seed Grass)

Eragrostis spp

Panicum natalense (Natal Panicum)

Setaria sphacelate var sphacelate (Common Bristle Grass)

Sporobolus stapfianus (Fibrous Dropseed)

Stiburus alopecuroides (Stiburus)

Melinis nerviglumis (Bristle Leaved Red Top)

Fingerhutia africana (Thimble Grass)

Chloris gayana (Rhodes Grass)

Themeda triandra (Red Grass)

Chloris gayana

combining grasses with flowering perennials

Grasses can be successfully combined with flowering perennials to add even greater colour and texture. Some flowering perennials that work well mixed with grasses:

Kniphofia spp (sometimes more water-loving)

Aloe spp

Bulbine spp

Helichrysum spp

Scabiosa columbaria

Crossandra greenstockii

Felicia amelloides

Pelargonium spp

Silene bellidioides

Agapanthus spp

Tulbaghia spp

Kniphofia

Bulbs that work well interplanted with grasses

Watsonia spp

Crocosmia spp

Crinum spp

Eucomis spp

Ornithogalum spp

Dierama spp

Scilla natalensis

Eucomis

Grasses can add value to any landscape and successfully implementing various species can bring a new South African aesthetic to landscaping. We have a wide range of beautiful plants from which to choose - Be bold with your experimentation of the Grassland Style Planting!

Combination of leaf shapes, sizes and textures

Combination of leaf shapes, sizes and textures

I always try put more emphasis on choosing plants according to their foliage for a landscape rather than choosing plants based on their flowers. Flowers only last a short season, but foliage lasts all year round. Don’t get me wrong, I love flowers and always add flowering plants to my designs but they are not the skeleton of the design. It is the texture - size and shape of leaves - that add variety and interest.

Grasses are wonderful at adding texture with their long flowing shapes that move in the wind. So are Kniphofias, Aloes and various succulents with different leaf shapes and colours. Bulbs (Eucomis, Crinum, Crocosmia) interplanted between grasses add interest and seasonal variety. Every year that my bulbs come up I am unexpectedly delighted!

I love combining plants that have large leaves with ones that have small, fine leaves. Succulents are a great choice as they are waterwise and require little water. They also withstand harsh weather conditions and will not die easily. Certain deciduous plants (Eg: Tree - Combretum krausii) turn gold, yellow and red before losing their leaves. This also adds seasonal interest and shows the changing of time and seasons.

So next time you choose a plant for your garden, don’t think about the colour of the flower but rather the leaf shape, size and colour and how this will complement the other plants. Here are a few lovely plants for adding texture to your garden:
