Deep Purple foliage on upright brownish-purple stems provides excellent texture and color to the landscape throughout the growing season. |
Soil - On the acid side of neutral, light sand and leaf-mouldy but able to retain moisture. Best sheltered in locations sheltered from strong winds. Requires support structure (Birch branch?) |
Adds architectural height and late summer bloom to a shaded part of the border or shade garden. Also effective in woodland gardens, cottage gardens and naturalized areas. Best in groups, although single plants have good specimen value once established. Try it at the back of a border, between evergreens. |
Actaea in |
Adiantum pedatum Hardy to -37 degrees Centigrade (-35 degrees Fahrenheit), Grows in North America, Central and Eastern United States, Canada, Alaska, North India, Japan and eastern Asia.

Dainty, bright green fronds are held aloft on shiny black stems. The fronds are in clusters from the clump-forming rhizome. Brighter light will reduce the size of the fronds but full sun does not make for a happy plant! It is content in gardens from Zone 2 (where it is clearly one of the most ornamental options) to Zone 9 |
The fronds are in clusters from the clump-forming rhizome. Dainty, bright green fronds are held aloft on shiny black stems, creating a light, airy texture in the woodland garden. In rich soil and bright shade it will spread by shallow rhizomes to form a dense groundcover. Found in the humus-rich woodlands and moist woods of Eastern North America. |
They have extremely delicate fronds. This as well as tougher more sturdy ferns are decorative in varied arrangements - in a long solid line or in a deep and wide group or in twos or threes or even singly. |

It is native to North-eastern America, Canada and Asia across the subarctic region in mossy woods, swamps, coniferous woodland and bogs. It is classified as a facultative wetland plant, meaning that it usually occurs in wetlands, but may occur in non-wetlands. |
