Plant Perennials

Make a small stream of blue perennials

 

Perennials are on the hitlist again. It is not so odd. You get much joy from a perennial bed and it is much easier to keep than a lawn, so maybe you should dig up some of your lawn.

Perennials are fabulous hardworking plants that no garden should be without. Most are easy to grow, require little maintenance and if you choose the right ones, you’ll have month after month of colour.

Herbaceous perennials die back in winter before re-emerging in spring when they put on a surge of growth. Some will flower in spring, some in summer and others, known as late season perennials, come into their own in late summer, providing colour as the garden fades into autumn.

Some perennials, such as heuchera and tellima, are evergreen and provide attractive mounds of foliage throughout winter.

In recent years the biggest garden trend has been to combine perennials with ornamental grasses – a design style known as the New Perennial Movement made popular by the Dutch designer Piet Oudolf, which takes its inspiration from the prairies and meadows of North America and has a naturalistic feel. Many of these perennials have fabulous seed heads and structure as the flowers fade, and if they’re left to stand over winter they provide interest, particularly on frosty days when the intricate structures glisten with ice crystals.

There are perennials that will suit all sorts of garden location and soil type. Most prefer sun, but there are plenty that will cope with some shade. The widest selection will be happy in average garden soil that’s moist but well-drained, however there are a whole host of perennials that come from the Mediterranean and parts of South Africa that will thrive in well-drained soil and cope with drought.

Perennials can be planted from early spring to late autumn and most should be divided every 34 years to control their spread and to reinvigorate the plants.

For those that have attractive seed heads such as sedums, rudbeckia and heleniums, leave tidying them up until late winter, but perennials that look worse for wear by the end of autumn can be cut back to ground level.
