Landscape architecture and architecture
are all about the purposeful
organizing of the space around us. Architects
work primarily with the
structural elements that enclose our living and
work environments.
Landscape architects design the exterior environment
and often the
transitional spaces between the interior and exterior
spaces. These
designers approach every project by creating a vision
- a concept - of how a space might feel, function
and look. Ideally architects and landscape
architects begin work jointly on a project so that
input flows between the design of the structure
and the design of the landscape.

about passing a personal favorite rose - in
my yard it is Purple Tiger, with its unique
coloring and fragrance - every day as you come
and go. |
The first task of a landscape designer
is to complete a thorough site
analysis. This includes a basic mapping of
the property which can be as
simple as a 1/4" = 1' scale drawing on graph paper.
Lot dimensions can be found on the property description
of your annual tax statement or by
requesting information from the plat maps at your
local city planning
office. Additional dimensions can be measured in
the field and added. Other information is also gathered
- including descriptions of contiguous land use
(what is next door), topography (changes in elevation),
soil types, existing vegetation, microclimate areas,
and the location of existing structures, utilities
and special features. In residential design
having a questionnaire that the covers the needs,
wants and dreams of the owners/occupants of the
property is a useful tool.
The second step of the design process
is not a single step but rather the
evolution of the overall design concept where numerous
ideas are examined, combined and refined.
It starts with simple rounded bubble or blob diagrams
drawn on sheets of tracing paper placed on top of
the base map. These diagrams will show various
possible alternatives in relationships between the
expected uses of the property. As the ideas
are refined one variation or concept design will
emerge that will seem to best satisfy all of the
needs of the people and the particular site.
Refinements will further define the spaces to be
used by the people, the circulation patterns, allow
for grading, utilities and service areas, and plan
for vegetation. Plants are used for a variety of
purposes in design - from creating focal points
to blending architectural elements into the landscape.
In general, vegetation will be described in terms
of how it might meet design needs - as in looking
for plant material with particular characteristics
of size, shape, color, texture and bloom.
The final completed landscape design
plan will define the character of the public spaces
- those areas viewed or generally used by visitors.
It will also will define the private spaces - those
used primarily by the residents for their needs
and interests, including hobbies such as rose gardening
and the service areas. This design plan will
be refined to where the created spaces will be dimensioned,
materials identified, additional structural elements
defined, appropriate plant materials selected and
a timetable suggested. Perspective sketches of the
completed project may be included along with elevation
drawings, if needed, and a planting plan detailing
specific varieties and numbers of plants.

The planting plan is created by
merging the concept design's descriptions of plant
needs by use and characteristics with actual plant
materials. Rose growers can apply the basic
principles to the placement of roses in their landscape.
Starting with the public space entry area of our
residences, which logically begs for focus, we may
consider adding favorite, or favored, roses to add
color and fragrance potential. There is something
wonderful about passing a personal favorite rose
- in my yard it is Purple Tiger, with its unique
coloring and fragrance - every day as you come and
go. Favored roses would include others with
special characteristics of striking color, long
bloom, pleasing fragrance and a height that puts
the bloom at viewer level. These roses might
be either container grown - adding a structural
element - or planted in the ground. Other
focal points or accent locations - areas that you
may wish to draw attention to - may be treated similarly.
Lucky for us, roses come with a variety of characteristics
- color, sizes, textures, bloom period, fragrance,
hardiness, etc. - which allows for multiple placement
within the landscape.
Most of us grow roses in separated
beds, which might in fact be the correct placement
for tender hybrids grown for competition in order
to minimize maintenance and to handle winter protection
constraints. Even these beds might be enhanced
by placing especially fragrant roses at the entry
points. Many of our rose varieties can also
be used to fulfill other landscape needs.
Roses, in particular varieties that do not need
winter protection, may be used to add height, color
and long season interest to cottage style flower
beds. In one mixed bed in my yard, within
a microclimate created by accumulating snow, hybrid
perpetuals flourish. Some of the more versatile
roses, especially the hardy Canadian developed roses
and the grand old garden rose varieties, may be
used to soften architectural features when placed
at building corners, the end of a fence or at a
change in elevation. Roses with longer canes
can be planted and trained to grow along a fence
or over an arch. William Baffin, John Cabot,
John Davis, Alexander MacKenzie and George Vancouver
are good candidates here - with William Baffin being
known for having the longest canes as well as complete
winter hardiness. These roses can work to
define space and to function as walls or even ceiling
elements giving enclosure and scale to an outdoor
space. Tree roses might also be used as vertical
elements. Sometimes we look to plant material
to provide privacy - visual and physical separation
- from neighbors or for screening an unsightly view.
Similar plantings may frame, and therefore enhance,
a welcome view or provide a backdrop for other plantings
at some special times during the season. Larger
roses may fill this need. Roses exist with
enough variety - and some with tolerances for less
than ideal conditions - that we can use them in
foundation plantings where they may need to accommodate
size constraints and other unique requirements.
Smaller roses would be terrific grown in mass plantings
where they would read from a distance as a single
unit. The smallest and lowest growing varieties
might be used to border beds and walkways.
Other varieties, especially those heavily endowed
with thorns, like the rugosas, would easily function
as effective hedge material forming visual and traffic
barriers. Of course, don't forget the roses
that have special characteristics in addition to
the beauty of their bloom, like R. glauca with the
blue green foliage, R. eglanteria and Applejack
with fragrant foliage and those such as R. blanda
with great fall color and bright hips.
