PAL Question:

Are there any lists of shrubs/small trees that are best viewed from below, such as Styrax or Halesia?

View Answer:

While there are no lists of shrubs/small trees best viewed from below, there is a list of trees with weeping habits in The Pacific Northwest Gardener's Book of Lists (Ray and Jan McNeilan, 1997). Many genera of conifers - Cedrus (cedar), Chamaecyparis (cypress), Larix (larch), Picea (spruce), Pinus (pine), and Tsuga (hemlock) - have weeping forms, often indicated by a variety name 'Pendula' or 'Pendulum'. There are weeping birches (Betula), beeches (Fagus), and cherries (Prunus), too.

You are correct about Styrax and Halesia. Additionally, I ran across a few individual species that may be of interest to you as I researched this question:
--Davidia involucrata
--Laburnum anagyroides
--flowering currants, Ribes spp.
--flowering cherry trees, particularly Prunus padus
--various plants in the Ericaceae family have bell-shaped flowers that hang on the underside of the stem.

I would add that any tree which has a naturally graceful branching pattern and/or delicately shaped foliage (such as Japanese maples) would be pleasant to view from below, as well as from other angles.

Keywords: Chamaecyparis

PAL Question:

Chamaecyparis pisifera 'Boulevard' is prone to foliage browning towards the interior of the tree as it matures. What is the cause of this and is there any remedy?

View Answer:

I consulted Pacific Northwest Landscape IPM Manual (WSU, 2002), which mentions that lower branches tend to die in older Chamaecyparis pisifera. This resource mentions cedar flagging as one of the cultural or environmental problems which may affect this tree. It is normal for evergreens to shed some old foliage every year, but this may be intensified by stresses like drought, recent or poor planting, root disturbance, or hot wind. Symptoms show up in the form of browned foliage, usually most noticeable in the fall. The current year's foliage stays green at the tips. Remedies for excessive flagging would include close attention to irrigation during periods of summer drought, preventing root disturbance, make sure the tree was not planted too deeply, and improve drainage if the soil tends to stay wet. (Replant onto a berm or raised bed, for example).

Since the browning you have observed is on the interior, flagging would be a likely possibility. Typically, the dead foliage gets blown out of the plant and the plant returns to normal growth in the spring. The following link, to a discussion on University of British Columbia's Botanical Garden Forums, may be of interest to you.

If you think something else might be going on, such as Phytophthora, you might want to bring photos and samples to a Master Gardener Clinic for diagnosis. Signs of Phytophthora begin at the small roots, progressing to larger roots. The inner bark will show a brownish color. Eventually, the foliage will turn color (yellowish to bronze and finally brown). This doesn't sound like your description, however.

PAL Question:

I am looking for evergreen hedges that will tolerate a windy site. Do you have any suggestions?

View Answer:

Sunset Western Garden Book (2007 edition) has a list of wind-resistant plants. From that list, there were a few plants which meet some of your site's needs (evergreen, fast-growing, about 7-10 feet tall). They are:

  • Arbutus unedo (Strawberry tree)
  • Arctostaphylos (Manzanita)
  • Ceanothus
  • Chamaecyparis
  • Cotoneaster
  • Escallonia
  • Morella californica
  • Pinus species (you would need a dwarf pine for your size limits)
  • Pittosporum (many of these grow taller than 10 feet over time, but P. tobira might work)
  • Pyracantha

I don't know if it is tolerant of winter winds, but Osmanthus delavayi makes a nice, dense evergreen hedge with flowers, and reaches about 8 feet. It grows fairly quickly also.

Two good resources for finding more information on the plants above are Oregon State University's Landscape Plants and Great Plant Picks.

Also, I found an article (no longer available) on wind tolerance from Colorado State University Extension which may be of interest. Here is an excerpt about the physical characteristics of wind tolerant plants:

"When considering which trees and shrubs do well in windy conditions, examine the shape and thickness of the leaves, stems and branches. Wind-resistant trees usually have flexible, wide spreading, strong branches and low centers of gravity. Wind tolerant shrubs often have small, thick or waxy leaves or very narrow leaves (or needles), to help control moisture loss. Plant species that have large, flat leaves "catch" wind. These plants have a tendency for branch breakage when strong gusts blow, or if laden with heavy, wet snow. Evergreen (conifer) trees are an excellent choice, having needles and being flexible in high winds."

Garden Tool:

The Pacific Northwest is an excellent climate for growing evergreens because our winters are generally mild. We can grow far more species than just Douglas Firs and Red Cedars, and in city gardens dwarf conifers are much more suitable. Explore the wide world of conifers, plants that produce cones, by joining the American Conifer Society. Membership costs $25 per year which includes a nice quarterly journal with color photos. Their website has a database with descriptions and photos, as well as information on becoming a member. Call (410) 721-6611 to join.

Favorite four conifers as voted on by members of the American Conifer Society:

  1. Picea orientalis 'Skylands'
  2. Abies koreana 'Silberlocke'
  3. Tsuga canadensis
  4. Chamaecyparis obtusa 'Nana Lutea'
