Gardeners' Notes:


On Feb 13, 2014, Rickwebb from Downingtown, PA wrote:

One of my favorite perennials for part shade or full light shade and a moist soil; though they can grow in full sun with moist soil. Handsome foliage and plumes and it does not need staking. Wonderful native plant to the woodland edges of eastern North America. The species is dioecious, so it has separate male and female plants. The male has slightly showier flower clusters, but in the trade they are usually not separated. Some are sold at most larger garden centers that have a good offering of perennials or at native plant nurseries. Too bad it is not found in so many yards as Daylily, Bearded Iris, or Peony.

bought two this year (2010) and they have done well by my back fence that gets shade most of the day. The "bugs" are feasting on the leaves and the deer have left them alone.

This is one plant whose blooms I really look forward to each year. It's lovely white delicate blooms really brighten up the darkest spot in my shady bed. It seems to tolerate dry spells very well. This plant prospers in an area where it is tough to grow much of anything else.

I grew 2 aruncus in full sun.They were not happy. Moved to a dappled shade area under a climbing rose & trumpet vines(lots of root competition) They did great. Did not require extra water. Showy flowers in early summer foilage stays fresh & green through season. If you have large bare spots in semi shaded area these plants work really well. Also they don't mind being moved

Goat's Beard grows all over South-central Alaska, along roadsides and woodland openings. It prefers moist areas, but seems to grow on raised embankments, as well. This plant is well-suited to the edge of a yard that is partially shaded, and has the advantage of growing quite tall in the summer, then dying back to the ground in the winter.

Goat's Beard self-seeds here, but is not always easy to germinate in cultivation. Cold/moist stratification, as it would receive in the wild, may be necessary. However, Goat's Beard transplants quite well and adapts well to cultivation.

Goat's Beard can be stunning in its late Spring and early Summer bloom, resembling a cream-colored large Astilbe.

There are only three species in this genus. Aruncus dioicus is also known as Aruncus sylvestris. Best cultivated in moist, rich soil, part sun/part shade. Good for around ponds or streams but happy in any moist soil. Grows to 6' tall and 4' wide. Gets flower 'spikes' that resemble Astilbe flowers but larger, they are usually cream color. Blooms in summer. Clump forming woodland plant. Propagate by division or seed. Hardy zones 3-9

Goatsbeard has 6-10" plumes of very small cream colored flowers. After flowers fade, the tall mounds of compound leaves provide a great background for later blooming plants. Native to deciduous woodlands of eastern and central US and also western Europe. Dwarf varieties are often mistaken for astilbe. The leaves are pinnately compound, bearing ... read more
