When you think about autumn plants, it’s tempting to concentrate just on foliage, but there are just as many flowers that are performing well now too. While most will only continue to bloom until the first frosts (depending on where you are in the country, this is usually early November), you can still plant and enjoy them now.
Dahlias are probably the best well-known of the late-season flowers and look good in a mixed border as well as in kitchen gardens alongside nasturtiums – try the nasturtium ‘Jewel Cherry Rose’ for an alternative to the usual orange.
But there are also sedums (which bees especially love), heleniums, chrysanthemums, asters, rudbeckias, eryngiums and sunflowers (helianthus) – all of which, together with plenty of grasses, will create a prairie-style meadow when planted in drifts – blocks of the same plant that run throughout your beds and borders. For inspiration, take a look at the work of Dutch designer Piet Oudolf, best known for his planting schemes for the High Line in New York and, a bit closer to home and well-worth a visit if you can, Hauser & Wirth’s gallery in Somerset.
At this time of year, you’ll need to buy any flowers as mature pot-grown plants to benefit from their blooms now, but this is also a good time to make a list of the plants you’d like to sow as seed in the spring to flower next year.
That’s not to forget foliage though, which, in autumn, can bring just as much colour to your garden as flowers do. Maples are one of the trees that do this best, and there are varieties for even the smallest of spaces. Underplanting them with hardy cyclamen is an easy way to create an autumnal woodland scheme. But there are also shrubs like Hydrangea quercifolia – a hydrangea with white flowers in summer and oak-like leaves that turn a deep, purple-toned red in autumn – and the smoke bush, cotinus, which gets its name from the smoke-like clusters of flowers that sit above its leaves.
Cotinus ‘Grace’ is one to try, with its foliage that turns from purple to brown to red, and its pink flowers that glow against the dark leaves, but you could also plant Cotinus Dusky Maiden ‘Londus’ for a similar effect in a small garden (smoke bushes will generally grow quite large – up to eight metres in height and spread in some cases – but there are plenty of varieties that’ll only reach just over a metre if you’re short on space).
Vitis coignetiae – the crimson glory vine – is another star foliage plant in autumn. It has impressive dinner plate-sized, heart-shaped leaves that gradually turn deep crimson and, eventually, gold. You’ll just need a large wall or house to grow it up.
