Some of the taller herbaceous plants also offer good screening for the summer and autumn, choose Aruncus
dioicus (Goat's beard) or Solidago "Golden Wings" (Golden Rod) for vigorous growth and showy flowers.
Let's end, however, by saluting the youngsters - The Night Sky Garden for Bord na Mona was designed by Harry and David Rich from the foothills of the Brecon Beacons, using stone with a pinkish tinge, acres of Aquilegia, Aruncus
, Astrantia, Asplenium, Hakonechloa, Peony and Thalictrum.
In their stead is a wave of astilbe 'professor van der Wielen' and a big plant of aruncus
dioicus, or goat's beard, both of which are said to prefer damp conditions.
Pharmacognostical studies on the Chinese crude drug "Shengma" (III) "Shengma" derived from genus Astilbe plant of Saxifrgacease and Aruncus
plant of Rosaceae.
Perennials will be planted in blocks in different layers, including iris, viola, dianthus, stipa and verbascum in full sun and thalictrum, gillenia, aruncus
and anemones in half shade.
Good combinations with these on poor draining, moist soil would be Astilbes with their fluffy spikes of white, pink, purple or red flowers, Ligularia for a splash of bright, daisy-like flowers and large heart-shaped leaves and Aruncus
dioicus (goat's beard), which has arching plumes of tiny, creamy white flowers.
For wet conditions, there is aruncus
, osmunda, hostas, rodgersia and Lobelia cardinalis to select from to create the effect you're after.
Hardy Geraniums, Acanthus, Ligularia, Macleayas, Hemerocallis, Achillea, Aruncus
, Rudbeckia Verbascum and Echinacea are all suitable for this "enhanced nature" style of planting.
