A pot of colourful daisies on the windowsill or on a sunny porch adds colour without requiring a lot of maintenance. These hardy flowers come in a variety of colours and sizes from the large, Gerbera daisies to the common white and yellow daisy. Daisies are perennial flowering plants that grow well with little additional care. A position in full sun or partial shade, good-quality standard potting soil and an application of balanced flower fertiliser three or four times a year, and a pot of daisies will grow and flower year after year.
