Hello. I hope this is the right place to post this question.

I'm in Portland and am looking at planting a columnar form of Big Leaf Maple (Acer macrophyllum) called 'Seattle Sentinel in my yard. My question is whether anyone has reliable information on longer-term height and width. The the few online sources seem to provide mixed information and before I made any decisions I wanted to complete some additional due diligence.

Hoyt Arboretum has one and I checked it out (photo attached) but it seems to be a fairly new tree.

Anyone have any good information about this tree?

Thanks in advance.

Jason

Sorry no one offered up any advice. You might try calling Big Tree Nursery or perhaps the Burke Museum (which maintains a database of NW plants). I am fortunate to have the space for our native big leaf maples and have several. They do take a lot of space per tree, and grow very quickly. Sounds like Seattle Sentinel has been bred to a more urban-friendly shape. Good luck, report back if you do opt for one.

I also have native big leaf maples. I totally agree with Bonehead, mine are over 90 feet. Look carefully at height.

I'm shocked that people seem to like big leaf maples. They rain spiky winged seeds everywhere in the spring, and the branches are weak and many tend to break off and fall every winter. The big leaves are super abundant and are a big pain to pick up every year. I guess they are a good source of shade? I love fruit trees like my apple trees, and I grow them in thick ground cover comfrey ground cover which needs no mowing, and discourages all weeds except the occasional blackberry vine or thistle. The leaves disappear over winter so don't have to be raked or removed.

I cannot understand how one could possibly be 'shocked' that folks like a certain plant. Big leaf maples are native in my region and I love them. As noted in my previous comment, they do take up a lot of space and are not likely a good choice for a smaller yard, but I am honored that they have chosen to grow in my forest. Stately tall tree, gorgeous fall color, provides feed and cover for many animals, has medicinal qualities. We all have our personal preferences.

That said, I'd look forward to a photo of your fruit trees with comfrey as a ground cover. Do you use common comfrey or the dwarf variety? I have both and find the dwarf will spread out quicker and does better in shade than the standard type.

According to this article the wood is very valuable.

Naturalnut, my big leaf maples are in a "natural" area that is 25' wide. The area was established by the county when zoning the area for development. Currently, the area that I pay taxes on has : 2 large and 1 small maple, a western red cedar, and over 11 firs. Most of the firs are over 95' tall and are about 100' from my house, the closeness is my main concern with the firs. After almost 5 yrs living at this location, I have noticed that the minor forest blocks the wind; only cause problems when a tree dies (my responsibility to take the dead ones down so that they do not land on a neighbors house, but not my responsibility if a living tree falls on a house. --unless it is my house); and does not block the view of the Sinclair Inlet with the ships entering or leaving the Bremerton Naval Shipyard, and the Bremerton/Seattle ferry. I also watch the birds in the trees, including owls, eagles, and Piliated Wood Peckers -- periodically see Red Neck Pheasants coming out to feed on the neighbors bird seed.

My last house was in Colorado, it sat on a 2.6 acre lot that had ponderosa trees. Most of them over 2'in diameter at the 3' level, one was about 4-5' in diameter. They provided needed shade and nesting area for Great Horned Owls that raised their young. I found it interesting have 3 white heads watching me when I walked in my back area, and when Mom and Pop hunted snakes, rabbits and squirrels. Also watched Western Screach Owl, foxes, deer, and rabbits. The Ponderosas were closer to my house than the firs are to my current house. I lived there for 22 yrs and only took out about 4 trees that were less than 12" in diameter-- they were either close to my house or my septic leach field.

Overall, I enjoy the trees (wish they were less than 75' tall) for the wild life they attract, except for the current deer that ruin my plants.
