Perennials for Bog Gardens

         Gunnera manicata- ‘giant rhubarb’ large umbrella-like leaves and prickly stems. In cold areas (prone to frost and water freezing) cover the crown with the dead leaves when it dies down in winter to protect the crown.

         Primula pulverulenta and candelabra primula flowers appear in early summer arranged in tiers up the stems. These plants self-seed readily in boggy areas - building up beautiful large displays.

         Darmera peltata‘ Nana’ - pink flowers appear before the foliage. Large saucer-shaped leaves appear after the flowers have faded. Beautiful, fiery foliage colours in autumn.

         Lobelia ‘Queen Victoriais a beautiful moisture-loving plant with upright stems of deep-red leaves topped with crimson flowers. Insulate the crowns with bracken or dead leaves in winter.

         Lythrum salicaria‘ Blush’ - a cultivated form of wild purple loosestrife; smaller than the wild plant; produces pale pink flowers in summer.

         Astilbe chinensis - fluffy pink flowers over attractive clumps of low-growing foliage to 20cm

         Iris siberica - Medium-height tough perennial with finer foliage than its larger-flowered cousins. Flowers come in many shades from white to dark blue.

         Ligularia dentata - this clump-forming plant has both ornamental foliage and flowers. Foliage wilts in hot summers if plants are exposed to direct sun light. Suitable for shaded areas along ponds, bogs or streams. Monitor plant for snails and slugs.

         Persicaria bistorta - A semi-evergreen and hardy, reliable perennial, excels in moist to boggy soil near water. Dense clumps of ground hugging foliage produce masses of soft pink poker heads held above the foliage throughout the summer. Native to parts of the UK.


Extra Hardy

Bog plants that tolerate full sun, wind and periods of dry to periods of flooding eg. dry summers after wet winters.

 

Acacia floribunda, retinoides

Brachysema lanceolatum

Eucalyptus rubida, viminalis

Grevillea confertifolia, juniperina, laurifolia

 

Trees for Wet Places


While there are a large range of trees suitable for wet places, it is important to note that some of these trees are too large for the average suburban backyard, or have very invasive roots that can cause problems such as blocked drains, raised paving, cracked foundations, etc. Good examples are poplar and willow species, which have been used extensively to stabilise stream banks - in the long term they may choke the stream, and require removal.

Acer freemanii (Freeman maple); mature height is 16-20m. Varieties include 'Armstrong', 'Autumn Blaze', and 'Celebration'.

Amelanchier spp. (serviceberries); mature height varies from 3-8m

Betula nigra (river birch) mature height 15-20m

Carpinus caroliniana; (American hornbeam); mature height 6-10m

Fraxinus pennsylvanica (green ash);16-20m

Quercus bicolor (swamp white oak); mature height 20m

Quercus palustris (pin oak); mature height 20-22m
