Learn about Beautiful and Versatile Perennials Perennials come in all forms, from herbaceous plants that die down in the winter and re-emerge in spring (year after year), to plants that retain their soft-stemmed leafy growth year round. Although beautiful, many perennials are also tough and very much adapted to a variety of climates - ranging from very dry to wet. Some have colourful foliage as well as beautiful flowers, others add architectural interest - but all add excitement and diversity to the landscape or garden as they burst into flower each year. Discover what perennials are, which perennial plants are most popular today, their cultural requirements (ie. feeding, watering, soil requirements, pruning, pest control), and learn how to use them to create beautiful landscapes. A course equally valuable to landscapers, nurserymen, cut flower growers and garden enthusiasts.
