Old English gardens have a special charm. Many of these gardens use mainly perennial flowers to achieve a lush, colorful oasis reminiscent of days gone by. It is not difficult to get this look in the home garden.

Perennials are plants that are long lived, sometimes dying back in the winter before greening up again in summer. They flower year after year and form the backbone to the herbaceous border. Annuals can be planted amongst them to add extra color.

Perennial Flower Garden Design

  • Draw a plan on graph paper and choose plants based on height and spread. Tall plants are planted at the back, going down to the smaller plants at the front of the garden.
  • The flower bed should be at least two meters wide by four meters long.
  • Consider the flower colors when planning the garden. Decide to have either bright hues or a pastel effect.
  • Plan to plant groups of one plant together to form a swathe of color.
  • Allow for the fully grown plant even if it will look sparse until the plants have grown. This can easily be overcome by adding annuals to fill in the gaps in the meantime.
  • Check in garden catalogues for times of flowering, growth rate and height.

Preparing the Perennial Flower Garden Site

  • The best time to plant a perennial garden is when the soil has warmed up in late spring.
  • Choose a sheltered, sunny site.
  • Use spray paint, string or an old garden hose to mark out the site.
  • Remove all weeds. This can be done using a natural spray.
  • Dig the area well and add compost and/or well rotted manure.
