Perennials play an important part in creating a beautiful and successful garden.
Perennials are plants that reappear year after year, unlike annuals that flower for one season then die. Life is a garden when you make it more interesting and beautiful by growing indigenous perennials.
Perennials have so many wonderful uses in the garden – they can be grown singly or in groups, as accent plants or as background, in borders, rockeries and containers. They are accommodating plants that combine well with annuals, bulbs, shrubs and ornamental grasses.
Our indigenous perennials are not only grown as decorative plants in our gardens, many are African herbal plants used in traditional healing. These include agapanthus, aloe, arum, bulbine, pelargonium, Leonotis leonurus, scabious and tulbaghia.
There are indigenous perennials for sunny or shady borders, for a scented garden or gardens designed around the theme of different colours. For example, white gardens are especially successful at dusk near patios as they light up the garden.
If you are planning a garden this weekend, consider including these perennials in your landscaping themes.
No scented garden should be without the queen of the indigenous perennials, the scented pelargonium. Known more commonly as scented geraniums, these indigenous perennials are increasingly being used as ornamentals in the garden because of their attractive leaf shapes and scents.
Plant them down a sunny pathway or near a sunny entrance or entertainment area. The most popular scented pelargoniums have rose, peppermint, lemon, apple and nutmeg fragrances.
Combinations of flowering indigenous perennials can be planted to create a glorious colour scheme in the garden. Consider these classic combinations:
Interesting use can be made of indigenous perennials as ground covers. These can be grown in swathes and sweeps and include agapanthus, yellow and orange bulbinella, clivia (shade), mauve wild garlic, weeping anthericum (Chlorophytum saundersiae) with arching grass-like leaves and tiny white starry flowers, and variegated hen-and-chickens (Chlorophytum comosum).
The carpet geranium (Geranium incanum), with finely cut foliage and magenta cup-shaped flowers, spreads a dainty carpet among taller growers. Wild garlic (Tulbaghia violacea) is a perennial that has strap-like green leaves and mauve flowers in spring. Tulbaghia will grow in partial shade under trees, on banks and as an edging, and needs little maintenance.
The wild iris (Dietes grandiflora) has dark green, sword-like leaves that grow in a fan. Their neat growth habit, and attractive large white flowers with yellow and violet markings, is the reason why they have become so popular in low maintenance and water wise landscaping.
