For ground that is always damp, but not permanently waterlogged, bog plants are a good group of plants to consider. These can be planted as part of a specially built bog garden or, if you are lucky enough, in any position in the garden where these conditions are naturally present.
Selecting plants for a bog garden presents many exciting options. Enjoy the opportunity to create contrasts with uprights foliage, bold broad leaved plants and filigree ferns. Add to this the variety of flower form and colour, and there can be interest throughout the growing season. Consider colourful stems of willow and dogwood for winter interest.
When choosing, buying and planting bog garden plants, keep the following in mind;
Water Garden Plants by Greg Speichert & Sue Speichert (Timber Press 2008, ISBN 9780881928464).Managing the Wet Garden by John Simmons (Timber Press 2008, ISBN 9780881929003).
These books are also made available through the RHS Lindley Library.
