PAL Question:

A friend asked me about screening two large propane tanks that, unfortunately, have had to be placed in front of their home on Camano Island. She mentioned wisteria to me and I shuddered. I've seen this plant do a lot of damage to trellis and home alike. Can you recommend, instead, an evergreen solution to this problem?

View Answer:

I am not familiar with the size and shape of propane tanks, but perhaps evergreen shrubs might work to screen them. A concern would be the proximity to the house, and any needed clearance for paths, doorways, and windows. I think you are right to avoid Wisteria. Does your friend prefer the idea of planting vines, or would shrubs be acceptable?

Here are a few suggestions for evergreen shrubs, with links from the local web site, Great Plant Picks:

Some good information is also available about plants for screening (from Virginia Cooperative Extension) and vines, especially evergreen vines such as Trachelospermum jasminoides, which might be a good solution. Local garden writer Valerie Easton on has written helpfully about hedges, as well.

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.
