Smoke Tree 'Golden Spirit'
Before moving to Washington, I used to frequent a forum where would-be transplants could post questions about living in the Vancouver area (housing, neighborhoods, schools or whatever was on their mind). I remember a post where the topic was the local flora. Of course, there was the usual appreciation of the beauty of the area and the wide range of plants. Then suddenly, a man who had just moved here interjected a rant about how he hated a certain tree that he saw planted everywhere in the city. It was the ugliest thing he had ever seen! After describing it, someone identified the offender as Smoke Tree (Cotinus coggygria). It was humorous to hear his opinions and it shows how people have differing views on plants.
Personally, I don't find the Smoke Tree unattractive at all although when grown poorly, it can look ragged. The guy from the post was referring to the Purple Smoketree (sometimes called Smoke Bush as it can be grown as a small tree or large shrub). There are many varieties of it and we grow 'Purple Purple' which is very common. A more recent introduction called 'Grace' is very popular with more orange-tinted foliage and it is indeed very attractive.
The gold-leaved varieties are somewhat different in look and form and perhaps the forum poster would like it better. I find 'Golden Spirit' to be a stunning plant and it was so beautiful this year. In the late evening in certain light conditions, it just glows. It isn't advertised as being as large as the purple varieties (most sources quote 8') although I have seen one in a neighborhood nearby where it is at least 12 feet tall. The blooms on 'Golden Spirit' are also not as prominent, if it blooms at all.
Smoke Tree grows extremely fast once it gets established. It is easy to train into tree-form by limbing up the branches by removing lower growth. Pruning in spring is said to curtail the puffy smoke-like blooms that appear later in summer but even if you didn't have the flowers, the foliage is still a major attraction. It looks good as either a specimen tree or mixed in border with other plants.
Comments
A purple smoke tree volunteer occasionally shows up in my garden. One year I decided to tend to it and train it on a single trunk. It is now taller than me and will be pruned for the fist time next spring. I love the leaf color and the contrast with Japanese forest grass growing at it's base.
