Looking for a little colour in your garden? There are many low-maintenance perennials that will produce beautiful blooms, such as day-lilies, Lilacs, Peonies, and Coneflowers, like the Echinacea purpurea Ruby Star (or purple coneflower). What gives day-lilies their name? These colourful flowers will open a new bloom daily, adding a burst of colour to your garden. Many are considered wildflowers, so be sure to tame these after a couple of seasons.
