There is an Fraxinus americana 'Autumn Purple', an ash that supposedly
has especially good purple fall color.

There is a book on Purpleleaf Plums by Arthur Lee Jacobson that
attempted to describe the many cultivars. There are several
purplish/reddish-leaved cultivars of Norway maple including 'Crimson
King', 'Royal Red', 'Crimson Sentry' and 'Goldsworth Purple.'

Other red/purplish-leaved trees include the following:

purple beech (Fagus sylvatica purpurea)
purple smoke tree (Cotinus coggygria 'Royal Purple')
purple English oak (Quercus robur 'Atropurpurea')
purple-leaved birch (Betula pendula 'Purpurea')
purpleleaf redbud (Cercis canadensis 'Forest Pansy')
purple filbert (Corylus maxima 'Purpurea')
red Japanese maple (Acer palmatum atropurpureum)

One purple-leaved tree goes a long way in a landscape as an accent
plant. They are often overused.

There is some genetic engineering work to develop better ornamental
plants. For example, their is a commercial effort to transfer blue
genes into flowers that lack blue shades, such as carnation and rose.
The Australian company Florigene has released several "blue" carnation
cultivars such as 'Moondust', 'Moonlite' and 'Moonshadow." However,
they are not true blue.

Thanks for all the good information above. It helps save me time in
listing all the purple colors of landscaping.

I do not know if there is a newsgroup for landscape architecture, but I
am interested in the science of landscape architecture. And I believe in
rows of
plants in order for it to be "pretty or beautiful" unlike the dottyness,
here a dot there a dot placement of trees. So that when you say "one
purple..tree goes a long way..... overused". I would disagree. I am
thinking of a 2 rows of trees of about 10 per row staggered of Norway
maples Royal Red mixed with Crimson King and staggered as in a
checkerboard with Sunburst locust. So that when someone drives by and
sees 2 rows of purple staggered with gold yellow is a sight to behold.

The trouble with the profession of landscape architecture is that they do
not use mathematics of proportions such as Golden Mean of its number 1.6
so that beautiful landscape architecture must have at minimum that of
rows and lines. Every landscape architecture that has no hint of rows of
plants or trees is a ditty dotty pattern and ellicits chaos and
randomness. Whereas lines and patterns ellicit order and thus beauty.

I am formulating plans on making 2 rows of staggered purple maples with
Sunburst locust trees.
