Growing And Planting Smoke Trees In The Landscape

Have you ever seen a smoke tree (European, Cotinus coggygria/American, Cotinus obovatus)? Growing smoke trees is something people do to make great looking shrub borders or even just as a pretty patio or accent tree in a front yard garden. When in full bloom, they have gorgeous reddish brown or dark mauve feathery flowers that make the tree look like a puff of smoke.

Planting smoke trees is easy enough. These trees make a great landscaping addition to most front yards. A lot of people prefer to use them as accent trees similar to the Japanese maple. When the smoke tree blooms, it makes a great accent.

Planting smoke trees throughout the border of your yard is another excellent idea for a pretty border that separates your yard from your neighbor’s that both you and your neighbor will enjoy.

Tips for Growing Smoke Trees

If you are planting smoke trees in your yard, you will want to know how to grow a smoke tree. This is simple enough. Purchase a good tree from your local garden center. They grow well in a high pH soil and should be located where they can get full sun or partial shade; however, they do prefer full sun and will bloom at their best in full sun.

When the smoke tree blooms, it is a beautiful tree. The puff of smoke that is the flowers will last most of the summer before it starts to fall off and fade for fall foliage. Again, the smoke tree blooms are like feathery, fuzzy flowers and look like a beautiful cloud of smoke.

Growing smoke trees is easy but you should be careful not to damage the bark. The bark is thin and easily damaged. Therefore, be careful not to hit it with a lawnmower or other gardening equipment while gardening. Weed whackers can also do harm, so again, use caution.

Pruning a Smoke Tree

The plant will also droop as it gets larger, so pruning your growing smoke trees is very important. Wait until late fall or early spring to do so after the tree is done blooming. You don’t want to stop the tree from blooming as the smoke tree blooms are the best part of the tree.

Pruning your smoke tree will make sure it grows up strong. Further, keeping the soil alkaline should help your tree be healthy as well. You can get food for the tree or treatments for the soil if you feel you need them from your local garden center.

Planting & Care

1. Planting: Choose a location where your tree will receive full sunlight (at least 6 hours a day). It can tolerate some shade, but does best when getting full sunlight. It’s able to grow in a wide range of soils, but be sure the soil is well-draining/

Dig a hole for your tree that is at least three times as wide as the root ball and equal in depth. Remove your tree from the container and gently loosen the roots by hand to ensure they grow in a spreading manner. Place your tree in the hole and position it so that the top of the roots are even with the ground and the tree is standing upright. Once the hole is completely filled, give your tree a deep watering to remove any air pockets and settle the soil. Apply 2 to 3 inches of mulch around the tree, ensuring that it doesn’t touch the trunk.

2. Watering: Ensure the soil around your tree stays moist but not wet during the first few months while establishing. Test the soil by feeling down 2 to 3 inches to determine if it’s dry and needs additional water. These trees are fairly drought resistant once established and will only need water every 1 to 2 weeks, depending on your climate.

3. Fertilizing: Fertilizing is not recommended – the Royal Purple Smoke Tree grows well on its own.

4. Pruning: Little to no maintenance is required when growing it as a shrub. Any dead or diseased branches can be pruned in early spring before growth appears. They can be pruned to grow as a tree form, but this should be done when planting. To do this, select a main stem and prune the other branches away, keeping more growth at the top.

Buying and Growing Smoke Trees and Smoke Bushes

The other day a visitor to the garden asked me how I grew smoke bush. There are two species of Cotinus and both grow in my garden.The American Smoke Tree, C. obovatus, is a rare native ofTennessee, Alabama, Kentucky and Texas where it can grow up to 10 metres tall by near as much across. Fifteen years ago I planted a small copse of this species. The plants were watered a little for a year or two after planting but haven’t been watered since. Despite this neglect from the hose they have flourished, growing well even during the drought years. I didn’t train them to a single trunk so they are more shrub-like in shape, the best being six metres tall by 5 metres across. During summer the egg shaped leaves have a bluish cast and contrast nicely with the pinkish flower panicles. During May these trees put on an amazing autumn show as their leaves turn brilliant scarlet, pink and orange. It’s as rare in cultivation as it is in the wild. When I was looking for trees to plant I bought every single one that was available in Australia at the time, a grand total of ten. Propagation from cuttings is difficult so seed is the usual option but germination is at best spasmodic and at worst fails completely.

The European species, C. coggygria, is much more likely to be found in Australian gardens and there are now half a dozen varieties available, all worth having. I pollard an old purple leafed selection, which could be ‘Foliis Purpureus’ or ‘Notcutt’s Variety’, I’m not sure which and the names seem interchangeable in Australia. Every winter I cut this shrub down to ninety centimetres. Whilst this means I don’t get any flowers the strong vertical new growth often reaches two metres in a season. These stems grow strongly well into autumn and still produce fresh, glossy new leaves right into April.

In the late 1970s Peter Dummer, then a propagator at the famous Hillier’s Nursery in the UK, raised five seedlings from a deliberate cross he had made between C. obovatus and C. coggygria ‘Velvet Cloak’. He named one of the seedlings ‘Grace’ after his wife. My plant of ‘Grace’ has been in for a dozen years or so. It was a brute to begin with sending out long floppy wands which made it more gormless than graceful. I nearly dug it out several times. It took a lot of work over many years to train it into something resembling a tree but now it is one of the wonders of the garden. The plum coloured flower panicles are huge and the pink veined, deep plum leaves are large and handsome. ‘Grace’ is now 6 or 7 metres tall and still throws out long floppy branches but these now give the tree an air of elegance. The autumn leaves are stunning turning red, scarlet, pink and butter.

At the other end of the scale from the tree like ‘Grace’ is Cotinus coggygria ‘Young Lady’ which has been growing for a few years in our New Mediterranean Garden. Naturally a dwarf shrub it has flower panicles at the tip of every growth and even the current seasons new wood. Whilst this makes it difficult to find good cutting material it makes it one of the joys. From all accounts it will grow up to 2 metres tall by a little less across although ours is still only 130cm tall. The flower panicles are green at first but soon turn dusky pink. All Cotinus are drought tolerant and frost hardy and to my knowledge have no known problems although they need protection from rabbits and hares when they are young.

Cotinus obovatus

American Smoke Tree, Texas Smoke Tree, Wild Smoke Tree, Smoke Tree, Smokebush, Chittamwood

Synonym(s): Cotinus americanus

USDA Native Status: L48 (N)

American smoketree is an upright, small tree or multi-trunked shrub, growing 15-30 ft. tall. Has a short trunk, open crown of spreading branches, resinous sap with a strong odor, and deep orange-yellow heartwood. Six to ten inch flower panicles develop long, red or purple, hairlike petioles that, in the crowded flower clusters, create a smoky appearance. (The flower itself is small and not showy.) Berries occur infrequently on pinkish stems; these also have a smoke-like look. Spring leaves are silky pink, becoming bluish to dark green. Fall leaves are magnificently colorful. A gnarled limb structure and the dark, flaking bark are other attributes. The masses of smoke-like fruit clusters with hairy stalks of sterile flowers give the species its common name.

Native to rocky, usually mountain soils from Kentucky, Tennessee, and northern Alabama west to Oklahoma, with disjunct populations in a few counties of central Texas, Cotinus obovatus is an outstanding small, ornamental tree. Its bark is decorative, its leaves are soothing blue-green in spring and summer and flaming oranges and reds in fall, and its flowers form ethereal clouds of pink and purple in spring. The floral panicles wave in the breeze, giving the illusion of clouds of smoke. It is drought-tolerant, disease-resistant, well-adapted to the stony soils of its native habitat, and should not be over-watered or over-fertilized.
