Flowers for small gardens

Alan Titchmarsh recommends plants for big impact in a limited space.

In small gardens, it’s wise to grow plants that bloom from spring until autumn. Space is at a premium in small gardens, and the longer a plant looks good, the more valuable it is.

In a small space, if you include plants that only flower briefly, choose ones that still look attractive when the flowers fade – for example, plants that produce attractive seedheads to continue the season of interest. Geranium macrorrhizum may not be the longest flowering hardy geranium, but its bright spring flowers are followed by crimson cranesbill seedheads that sit neatly above the dome of aromatic, hairy leaves. Hydrangeas flower through summer into early autumn, but their dried seedheads will see you through winter.

Delphiniums and lupins can be encouraged to give a second show of flowers by cutting back the faded stems. Add well-rotted organic matter and blood, fish and bonemeal to enrich your soil. The ‘Chelsea chop’ is another way of prolonging flowering. Achilleas, campanulas, nepetas and phlox all respond to this treatment.

Try to ensure that some long-lasting flowers are positioned near your front door so you are welcomed home when you come home. If you’re home in the early evening, create a spot where you can sit and enjoy the evening fragrance of tobacco plants (Nicotiana) and roses such as ‘The Generous Gardener’ or ‘New Dawn’.

Some plants will never bloom for more than a few weeks, such as oriental poppies. But when the last of the tissue-paper flowers has faded, the ugly foliage can be scissored off at ground level so it doesn’t flop over other plants and rot in summer rains. Dahlias are quite late to start blooming, and they have a lot of growth to put on before they begin to flower. But, once they start, they don’t stop until the first frosts of autumn.

Any plant that flowers for five months of the year is well worth growing in a small garden. Sweet peas will do their best if their flowers are cut regularly.
