Shrubs for Sun

Viburnum sargentii 'Onondaga' May 2009

Juniperus chinensis December 2009

These shrubs for sun are all good plants for gardens in Seattle, the Pacific Northwest & USDA Zone 8. They have good form, lovely flowers, colorful foliage & other characteristics that endear them to many gardeners. Some of these shrubs tolerate dryness, others are xeric plants that prefer well-drained soil. Most of these should be fairly easy to find. When local nurseries fail, try mail-order nurseries.  Forest Farm is a good source for uncommon plants.  This list is not meant to provide detailed information on shrubs, but to introduce you to some you may not know, or remind you of those you have forgotten.  Be sure you know how large these shrubs grow before you plant them.  Many shrubs do not look good when sheared or heavily pruned.  An abundance of detailed information is available on the web.  Good reference books on shrubs are The Hillier Gardener's Guide to Trees & Shrubs edited by John Kelly, Shrubs by Roger Phillips & Martyn Rix, Sunset Western Garden Book.
