PlantFiles: Smoke Tree
Cotinus coggygria

Please, note, this is not a plant for wet or heavy soils! Here in Bulgaria, where it is native, it grows on sites that are highly unsuitable for other plants, i.e. dry, rocky, hot, infertile, calcareous soils. It is to be seen at such places along roads, and is easy to recognise in fall, when it is most conspicuous due to the brilliant crimson colour; otherwise it blends with other plants into a green mass.
I grow a Royal Purple individual in Krapets, and it does fairly well, considering the soil, which is very fertile, yet dryish.
It has attained massive proportions and a great age in Balchik, as can be seen from the photo I've posted. The soil is perfect - a poor, shallow chalk, overlain with the thinest of humus layers.

One of my favorite shrubs/trees, especially the purple varieties(I do own a young lady(green) and its a small beauty,
really flowers out and its tuff. I put in a nice velvet cloak
several years back and even though it had some die back
occasssionally it was always beautiful dark deep marron
colors. This year I waited for it to do its thing and nothing,
it did not come back, well I trimmed its 5 ft size down to
3 ft. and after a couple weeks there is some growth coming
out of the base but I may wait and cut the rest down to this
new growth and hopefull start again. My two royal purple
smokes are ok, a really nice selection as well, just amazing
color but it doesn't "smoke" out like the greener ones, its
still a knock out color in the landscape with great fall
colors. Nice red outline on the purple leaves, I may need to give the velvet
a light mulch even though I don't want them to get wet
feet, especially in the winter. I have my velvet cloak on a slight hill for good drainage
I have enjoyed growing these., want to try the golden one next. I still don't know what happened to the Velvet Cl variety,
it was a milder snowy winter here in southeast NH, I expected
it to come back with no die back and now its barely even
alive?? Any feed back appreciated.

In Minnesota most planting are of the purple leaf varieties. The harsher climates of zone 4 here keep most plants small - in some area they are almost herb - like, dying back to a few inches above the ground every year - in a suburban yard I have seen a medium size shrub at about 6 feet in height, and yet there are huge speciments at a private college near or in St. Paul - I forgot the name but the smoke trees were in a central plaza surrounded by buildings next to walls so it increase a zone there and are more of small trees to about 20 feet tall - maybe more but hard to remember. Hardiness may vary like crazy, especially between different cultivars.

This species is very suspectible to verticillium wilts that causes diebacks of the branches and sometimes kill the entire plant.

It sometimes get spots infections on its leaves.

For the past 4 or 5 years I've had several of these smoke trees as I love their color and texture. All of a sudden the tips of one of mine has turned brown and appears to be dying. I don't get it - all of my trees have been doing so well. Any thoughts - anyone?

My smoke tree is doing poorly, perhaps owing to the clay-heavy, non-draining soil. I think it's just too wet. The top leaves on each branch are wilting and dying.

I have three of these that have made it through three winters in the Catskills. They are in full sun on a hillside with lousy soil--clay and rocks. The are quite full, growing as shrubs. I have neither watered nor fertilized, although I did wrap them in burlap their first winter. I was inspired to plant them by a really spectacular old tree in a local cemetery.

I planted this about Sept. 2002. Although it leafed out and created "smoke" normally this spring, the growth is almost on one side and and doesn't seem to be creating any ladder branches. I think this is referred to as "lions tail".

As it has only been in the ground for a year, my intention was to let it start to find its own shape before attempting any pruning but I am concerned about winter snow-ice-wind damaging it.

I have two plants. One is a burgandy color and the other is green. Both of them have a condition I believe is called "Lions Tail" which results in very long branches with the blooms and smoke at the ends.

Seedlings show a lot of variability in the leaf color; best to get cuttings of known varieties rather than seed-grown (which are much cheaper).

In America, this is often called the European Smoke Tree to distinguish it from Cotinus obovatus, the native American smoke tree. The showy "smoke" actually appears after the flowers which are small, kind of dull yellow and inconspicuous. It is composed of the seeds and seed stems. It is very unique and eye catching. As with many purple leaved trees and shrubs, the leaves of the purple-leaved varieties such as 'Royal Purple' and 'Velvet Cloak' are most intensely purple early in the season and gradually fade somewhat towards green as the leaf ages. This effect seems more pronounced on cotinus when in the shade. A relatively new variety, 'Grace', is reported to have especially large 'smoke'. It is a cross between C. obovatus and C. coggygria.

In the beginning of Spring, (when I planted the tree), the leaves have a grayish burgundy color and do not get wet by water (like waterproof). Stays very healthy looking with no effects from insects and bugs ( up until the summer, now)

Needs well drained soil and moderate watering when young. Once established, it's drought tolerant.

This plant has done better since I moved it from too much shade. Not as 'purple' as the nursery photos showed however. During the summer, leaves have a reddish green tint, and more red in the Fall. Slow to moderate grower.

It produces inconspicuous plume-like puffs, hence the name.

A deciduous shrub that may be trained as a tree, growing to 15 feet tall.
Leaves are alternating colors, with green on the top and blue on the bottom. This causes a very interesting and appealing pattern when a gentle breeze blows the leaves around.

In June, blooms appear. The flowers have plumy hairs, resulting in a smoky appearance surrounding the flowers, hence the name "Smoke Tree".
