Plant of the Month

Hydrangea paniculata 'Dharuma'

10th Anniversary Celebration

Hydrangeas are among the most beloved of all garden shrubs. From the jewel-like blues of the bigleaf hydrangeas to the bold foliage and incredible fall color of our native oakleaf hydrangea and the vigorous but occasionally reticent to flower climbing hydrangea, these plants add color and drama to our landscapes.

While the bigleaf hydrangea (H. macrophylla) is the undisputed king of the hill among hydrangeas. Another popular Asian species is the panicled hydrangea (H. paniculata). This species is an old-fashioned, large shrub, notable among the hydrangeas for its tolerance and even appreciation of sunny spots. It flowers on new growth making it amenable to a haircut in winter or early spring which will give it time to produce flowers in mid-summer. There have been many selections of this plant which is not only among the most heat tolerant and floriferous but also perhaps the cold hardiest surviving even the tundra-like conditions of USDA zone 4. One of our favorites is the very dwarf form called 'Dharuma' which was brought to the United States from Japan in 1989. It is sometimes confused with 'Darlido', a Dutch selection of different parentage. 'Dharuma' has been one of the few plants that has stayed smaller than we were originally led to believe, generally growing to only about 3' tall. The foliage on this selection is attractive glossy green, nicer than many other panicled hydrangeas and the flowers are held in somewhat flattened panicles as opposed to the typical cone shape of the species. Some hydrangeaphiles have suggested a bit of hanky-panky may have occurred in its past, perhaps with H. heteromalla, a typically very large species itself. The flowers on 'Dharuma' emerge early and turn from pristine white to rosy pink. The leathery foliage makes it much more deer resistant than bigleaf hydrangeas. We've been very impressed with this selection and think it has a place in most any garden.

Garden Conservancy's Open Days

Barbara and Loren Kennedy's garden

by Jayme Bednarczyk JCRA Member and Volunteer and Garden Conservancy Regional Representative

September 15, 2011 – 9:00 AM–5:00 PM
September 16, 2011 – 12:00 PM–5:00 PM

There is no better way to learn about gardens than to spend time in them—with the gardeners! Experience five distinct visions—guaranteed to inspire, relax, and entertain new ideas and ways of thinking about your own landscape.

This year’s self guided tour of America’s best private gardens include five in our region:

The Werner Garden – This informal collector's garden features a 2,800-square-foot herbaceous perennial border, colorful annual plantings surrounding an inground pool, a gazebo surrounded by a large planting of herbaceous perennials and shrubs, natural areas with mixed shrub and tree plantings, and foundation plantings featuring a variety of small trees, shrubs, herbaceous perennials, and ferns.

The Maynard Garden – Meandering paths lead visitors to a peaceful reflecting pool; intimate and hidden gardens featuring obscure plant cultivars and an electric collection of sculpture; a whole new, large, open garden; a vine covered pergola; an oval-shaped parterre planted with various herbs, boxwood, and a multitude of flowering plants; a large stone moon gate; a meditation garden; and a whimsical children's playhouse.

Quarry Hill – Nestled in a serene woodland setting of mature oaks, pines, and maples, Quarry Hill captures the eye with its traditional roots and delightful garden accents. Overlooking a peaceful lake, native ferns, wildflowers, and many varieties of perennials are showcased and ensure constant color and interest in this beautiful city garden.

The Sorge Garden – There is something for everyone at the Sorge Garden. From an unusual and private front yard garden filled with trees and shrubs, a rose arbor, and a stone walkway that leads to raised vegetable beds, grape arbors, and a greenhouse.

The Gardens of Ashland Hall – A stunning one-acre botanical feast, the Gardens of Ashland Hall is a delightful mix of several garden styles including the cutting garden, the cottage garden, the English garden designed around the unique heart-shaped lawn, and an impressive tropical garden, complete with a Tiki hut.

The Umstead Hotel and Spa Garden – The Umstead uses native North Carolina species to create a sense of place reflective of nearby Umstead State Park, while select exotic species enhance the scenery with their unique shapes and colors as they are seamlessly woven into the relaxed landscape design.

We so appreciate the generosity of the garden hosts for this important fund raiser that benefits both the Garden Conservancy and the JC Raulston Arboretum!

Admission to each private garden is $5, payable at each location. Discount ticket books (six tickets for $25.00) are available in advance at the JCRA and at each garden during the tour. For additional details, please visit the JCRA's Web site.
