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.
