Perennial flowers are fabulous additions to the garden with their rich waves of colorful blooms that can be enjoyed from spring to fall. And gardeners in the Pacific Northwest region are blessed with a wide variety of herbaceous perennials to pick from.

This region is famous for its abundant production of dahlias, lavenders, garden lilies, and many more perennial plants. Some plants grown as annual plants in other parts of the country (e.g. Iceland poppies or carnations), will happily overwinter in the Pacific Northwest and re-bloom the following year. An Eden for plants!

However, carefully selecting plants suited to the Pacific Northwest climate will be a key step to success. Plants will have to be drought tolerant to cope with the summer months with little or no rain. They will also have to survive the regular cold rainfall in winter and should be resistant to fungal diseases (as a result of the high humidity).
