Ive studied this species since 1960ish, in middle TN. Collected crossections from numerous fallen trees. I have planted many, and kept growth records. Ive never found a giant sycamore over 80 years old, proven by growth rings. The Tennessee largest record holder in Shelby Park in the mid-1990s was only 35 years old (you can read my story about it on my website). I have recorded growth rates of 8 feet in early years, but 3 to 5 feet is more common its first 20 years. My current sycamore is 15 years old, 65 feet tall, 20 inches dbh, and has never been watered or pampered in any way. I could share so much, but not enough space here. smile.

The Sycamore tree is a fast growing, large tree here in the east. The tree is not recommended for planting near sidewalks, driveways or smaller yards. Give this tree a lot of room in more open areas as it does really well along streams and wetland sites. What I really like about this tree is it's ability to develop cavities and still maintain it's strength. In my area, the Sycamore and the Catalpa trees provide cavities for many animal and bird species to den in and take refuge while at the same time remaining structurally sound for years in a hollowed condition. I have walked into Sycamore cavities at ground level and was able to look up into the hollowed tree for 20 feet or more.

I live in Knoxville TN. My backyard is completely open to the SW winds that funnel most of the leaves from the 5 Sycamores that are located on a nearby school property, onto my property. The leaves defy composting, blowing,raking, corralling in any way. Any that you may miss, when cleaning out your planting beds, you will find years later. One year, one of my backyard hedges was completely covered by these leaves and, the leaves were piled 10' out from the hedge. If you want to be a problem to your neighbors downwind of your property, plant these horrible trees. Otherwise, respect everyone and get rid of them or, better yet, never plant them.

The previous owner of my house must have loved sycamores as there were five in the yard. One didn't thrive for unknown reasons and I cut it down.

They produce a dense shade that is welcome in Florida. Then they loose all of their leaves in winter allowing welcome sun. I use the leaves for garden paths and eventually in the garden beds.

If you are thinking of planting a sycamore you need to consider their mature size. The canopy of one tree can be 50 feet wide. I don't care for branches hanging over my house. I may end up cutting two of the trees for that reason.

If you intend to plant a sycamore, possibly consider its relative from south of the border, Platanus mexicanus which is not as susceptible to powdery mildew. It also has beautiful silvery color on the abaxial surface of the leaf.

I bought a house in 1998 that didn't have any trees. I tried planting a couple of oak trees but they died. My girlfriend gave me a small seedling from one of her Sycamores and I planted it but thought it would go the way of the oak trees. Boy was I wrong! It took to the soil like me to a hot pancake. About a year later she gave me another one that I planted in the back yard and now I have two beautiful trees that completely changed the look of my property for the better. I planted them around 2003 and 2005 and they both are over 25 feet tall. They are the bain of the neighborhood though in the fall when the enormous leaves start to fall. You can expect 5 to 7 feet of growth per year at least that's how fast mine have grown here south of Houston TX. I really like mine.

This grows to be a large shade tree and is best used in large yards or parks. It is also a common tree of open woods, wetlands, and long watercourses; native from southern New England to eastern Nebraska to east Texas to northern Florida. It is fast growing of about 2.5 to 3.5 feet/year and lives about 250 to 350 years. It is tolerant of urban conditions of heat, drought, and pollution where it is often used as a street tree, even though it is messy with falling twigs, pieces of bark, and round dry buttonball fruit (borne singly). It often losses most of the first crop of leaves to anthracnose fungus from cool, wet spring conditions and its foliage is browned by Sycamore Lacebug in late summer.

If sycamore trees are self pruning and always drop branches before they can die and then the dead branches just sit there, I'd suggest collecting seeds from the one at Georgian and Fawnridge in North Austin. 9103 Fawnridge comes up when you click on the house in Google Maps. In street view the tree comes up. Now Google must have visited in fall, because at the moment the tree has healthy bright green leaves on all the living branches.

When I first saw it I didn't know what kind of tree it was, and thought that the fact that something clearly ate most of its bark accounted for the extensive dead branches. (The bark normally looks like that.)

Contrary to the previous comment about branches, although I don't typically see dead branches on trees, I've seen way too many incidents of living branches breaking off trees. These are sometimes very large and potentially very damaging when they fall. This seems to be an issue here in Austin at least, more than any other tree I've seen. Other trees will drop dead branches. This one drops live branches. Yikes.


On Nov 15, 2010, Gardeningman from Kingman, KS (Zone 6b) wrote:

I love the American Sycamore tree. It is a very, very good tree. The reason why it drops twigs, is because it is self pruning. You never see a dead branch in a Sycamore tree, which is one of the reasons why it looks so beautiful. I often see dead branches in elms, maples, and oaks. Their dead branches persist and usually need to be mechanically removed.
Someone earlier made the comment that these trees die after 100 years old. This is not true. Sycamore trees can live to over 500 years old.
For those who complain about the leaves, my suggestion to you is don't plant any tree except for the Bald Cypress, because all trees produce leaves that need to be raked except for the Bald Cypress.

Zone 5 encourages late leaf-out for the Sycamore. It is the perfect tree to under plant with early spring bulbs and plants. The red peonies passed down to me from my mother have thrived under the sycamore tree for twenty years even though they are in deep shade for most of the summer! The red tulips nestled among the hosta, forsythia and kerria are also gorgeous in the spring under the tree. Closer to the drip line I planted a rhododendron five years ago. It gets bigger and more beautiful each year. This tree is a beauty and worth the trouble of picking up a few twigs!

I have a 40 yr. old Sycamore in my front yard. I love it. It is a beautiful tree, the bark is so unique and pretty. The twigs that fall are always interesting, they have much different characteristics than most tree branches. I will admit that it can be messy, but what tree isn't? It really doesn't take very long to go out and pick up after it. I think the leaves are cool too. I have always loved the scent Sycamores have, especially in the spring and summer after it rains.

There are many sycamores in the Pennsylvania river valley where I live. The best planted specimens are in large open spaces such as cemeteries and campuses.

These grow naturally in corridors along the river and along highways but rarely seem to be healthy and able to obtain their natural form. Perhaps the tree's native habitat is frequently adapted to farmland and housing.

There are a few of these planted in the downtowns here and they seem to be a poor choice. They are out of scale (too large) for the narrow streetscapes of our region where trees are usually planted within 6-12 feet of the houses. The roots frequently damage the sidewalks. They drop quite a bit of bark and their seed balls are messy as well. The leaves blow around due to their large size an... read more

All the complaints about the sycamore may be true, but they can also be positive.
I was attempting to convert an overused pasture back into a woodlot here in northern Illinois. Most of the topsoil was eroded by cattle and few of what I consider to be quality hardwood and pine trees would grow. The reforestation started with box elder, silver maple, alder & locust that provided some shelter and shade for the hardwood seedlings that are native in our area.
Then I discovered that sycamore (also native) likes the clay just fine. It tolerates bone dry hard pan clay, but will grow fastest in the lower, swampy areas. It will grow taller and faster than cottonwood. I've removed the cottonwood and replaced it with sycamore in the wet areas.

This is a beautiful tree -- way down at the edge of some woods, but NOT in a yard. All summer and fall it drops lots of big curly leaves that blow into the neighbor's yards and just lie there for weeks if no one cleans them up. It's also very weak wood because of the rapid growth, and big limbs will break off, not to mention lots of sticks that fall all the time. A local nursery owner talked us into planting one in our front yard years ago and I still haven't forgiven him. ;-) After years of cleaning up the mess from our yard and the neighbors', we finally shelled out the money to have it cut down and planted a nice willow oak that has served us much better.

The Sycamore is considered a hardy city tree and is planted all over the streets of New York City. It is indeed messy but what I dislike most about it is that it is the last to leaf out in the spring and then starts turning brown and dropping leaves in late summer/early fall. Since trees are supposed to add beauty (and air filtering) to city streets, why choose one with such a short green season?

This tree does have a sweet smelling scent especially on hot sunny humid days, smells sort of like sweet human sweat. I only noticed it when I started to grow some seedlings, Then I smelled their leaves and noticed it, It is not a strong smell but it is there, if you are near a Sycamore see if you can smell it. get downwind of the tree. Also it's seedlings leaves do not have that classic Maple leaf shape, I noticed I have never seen a Sycamore tree smaller than 5 feet, so I grew some seedlings to see why, it's cause they look totally different than the adult. Their are more fan shaped.

These are very large stately trees. Because of their extensive root system, they are very windfirm. However it's a shame they have a problem with anthracnose. It kills off new growth in the spring which creates a "witch's broom" of new growth afterwards and makes the tree look sort of deformed.

A bit of caution to those who wish to collect seeds from the seed balls:

The tiny hairs on the fruit clusters can irritate the skin and, if inhaled, the respiratory passage. The chaff and dust generated during processing of fruits to extract the seeds is dangerous, and people who do this must wear protective masks. Sometimes the growing roots can clog sewers and damage sidewalks, and fallen leaves can clog drains. American sycamore is a fast growing tree. Don't plant it too close to buildings and utility lines!

The mighty sycamore as I call it, is a FL native to mostly the upper left hand side of the state but they are growing successfully much farther south. I have seen them as far as palm beach county and I have seen them growing in what looks like pure sand along the river in brevard county. Older sycamores have been found with hollow trunks. (think Winnie The Pooh's home) If you're looking for fast shade, plant a mighty sycamore. Although they have a reputation for not being such great trees in storms, all the sycamores in my area survived the recent hurricanes with flying colors.

San Antonio, Tx.)
The American sycamore is sometimes confused with the several other trees in the same genus which are similar in appearance. If the tree has single seedpods, it is an American sycamore. If there are two seedpods together, it is a London planetree (Platanus X acerfolia). If there are 3-5 seedpods, it is an Oriental planetree (P. orientalis) which has the seedpods hanging like beads. All three have lobed maple-like leaves, but each is slightly different. American sycamore's leaf lobes are wider than long. London planetree's leaf lobes are about as wide as they are long. Oriental planetree's leaf lobes that are much longer than wide and deeply incised. London planetree is a hybrid between the American sycamore (Platanus occidentalis) and the oriental planetree.
