A couple days into our two week honeymoon in St. Lucia, a perfect Caribbean sunset...

As they say down there, "No pressure, no problem."



If you want to start learning your oak trees this is a great one to start with. This is a young pin oak, Quercus palustris. On this foggy morning on the way to work I was elated to find this little guy because you can see one of the most interesting aspects of this particular species. Pin oaks have an attractive pyramidal habit in their youth and it's due to their unique branching. The lower limbs are pendulous, or weep slightly, the central limbs are horizontal, and the upper limbs point upwards toward the sky. Now you might think all trees limbs grow that way, as I did at one point in time, but as you reexamine your local trees you will see that this habit is really quite unique to pin oaks, and therefore makes them relatively easy to identify in the landscape. Most pin oaks planted in parks and yards can get limbed-up (the lower limbs pruned off to allow for easier passage underneath) so you eventually lose this quick indicator, perhaps another reason I was excited to find this specimen posing so perfectly this morning.
Red maples, botanically known as Acer rubrum, are a great northeastern shade tree for many reasons. In spring before they leaf out (March into April) red maples produce great looking clusters of red flowers (click here for image of flowers). That in combination with the smooth gray bark was how I was able to identify the tree above when we moved across the street last winter. Our new neighbors talked about the amazing red fall color and just recently we got to see for ourselves.
These shots are of some red maple cultivars up at the new York Botanical Garden. You can see here the difference in the leaf. When people think of maples they tend to think of that quintessential 5-pointed or 5-lobed leaf silhouette. Here you can see that red maples, though they still have five lobes, tend to look more like a leaf with only three points. This can help you identify them in the summer when most maples are rich green in color and not so easy to tell apart. But then in fall of course we are further clued in as to why they are called red maples. As far as your standard list of maples often used in the northeast Norway maples (invasive bastards!) have a bright yellow fall color. Sugar maples can be every fall color imaginable but end up showing mostly oranges. But the red maples will always get this real intense red to scarlet coloration when they change in early November.
Younger trees have a smooth gray bark that helps you to identify them in the woodlands. They are also sometimes called swamp maples and as the name might suggest they do really well in a more wet situation. Often in a forest setting you will find them naturally living down closer to the stream edge or in lower, soggier areas. As the trees mature the bark transforms from being smooth to having these long vertical ridges and furrows, still a nice light gray. This mature specimen is located in the old growth forest up at NYBG.
There are of course a gazillion cultivars of red maples out there so you want to check your local nurseries and do your research before buying. I remember back when I was in the nursery trade we sold a lot of 'October Glory' and 'Red Sunset' but gosh, that was a good ten years ago.
As an alum of the School of Professional Horticulture I was invited up to the New York Botanical Garden on Saturday to enjoy a forest symposium by leading scientists and policy makers. From a global scale to a local scale four speakers addressed the challenges we face as stewards of the land going forward in this time of climate change and then we all went out and enjoyed the 50-acre old growth forest that NYBG is known for. Reuniting with friends and mentors it was such a treat to give our bodies a day off while exercising our minds and getting re-inspired to continue plugging away at the good work we do. I have specific tree shots and info to share but for now here are some of the more general shots I took that gorgeous afternoon. (as always click to enlarge images)
probably a tulip tree (Liriodendron tulipifera)
What most people don't realize is that the stunning colors we see in fall are actually there in the leaves most of the growing season, they are just hidden by the chlorophyll plants produce in order to photosynthesize.
As trees and shrubs begin to go dormant in the fall they produce less chlorophyll, the green pigment in their leaves, because they have to begin shutting down and storing up water and sugars so that they can leaf-out next spring. With less chlorophyll present we get a glimpse of the other pigments in the leaves that are created throughout the growing season. Xanthophylls and Carotenoids are responsible for the stunning yellows and oranges and actually exist in the leaves most of the warmer months. The red and purple pigments come from Anthocyanins which the leaves manufacture mid- to late-summer to deal with the bright summer sun, almost like a plant's secret SPF. In fall we get lucky that the trees and shrubs take a little time to shut down and prepare for winter dormancy giving us this great show.

New exceptionally designed pathways now weave throughout the Thain Family Forest allowing arborists and novices alike the chance to experience this wonderful woodland with all it's age and lessons on the interconnectedness of life. Such a treat to breath easy, dwarfed by the landscape, and take it all in.
In the woods in fall you can find these great shots of yellow coming from various hickories, the genus Carya. Hickories can be easily identified with that unique compound leaf that stands out. Some have better fall color than others but all add this wonderful punch to the changing landscape. This was taken up at the New York Botanical Garden last weekend and don't worry, I have plenty more where this came from....
I decided to take my camera along for my little walk and errand running this morning. Even though just a Hosta in this small cement urn I couldn't help but like the way the sun was hitting it from behind.
Everywhere in my neighborhood you see these small herbaceous plantings, such as these mums, peaking through the chain link fence in search of the sun. Get it, kids!
I could create a whole blog that was just old dilapidated laundromat signs from around the city. There is something about each sign and storefront that makes it unique, like the funny crooked ampersand.
People do some fabulous container gardening here in Astoria, land of the Greeks. Here they started with tall, narrow pots planted with red Mandevilla, a great flowering vine of an annual, and trained it up to create this whole elaborate trellis you walk under when coming or going. ...pretty fabulous.
Then I had to get stuck looking at all the new street trees. The Parks Department is about halfway through the planting efforts associated with their Million Trees NYC initiative which means over 500,000 trees have been planted in the last four years or less. As an arborist it's great because I never have to go far to find myself noticing new trees, eagerly trying to identify each one.
I am guessing that this new addition is a young black oak, Quercus velutina. Many oaks within the red oak family can look alike so often you have to carefully examine other parts of the tree in order to make your best educated guess. You need to look at things like the buds the trees set in fall that persist through winter.
In some cases you need to take into consideration the bark.
In both cases the buds and the bark seem closest to a black oak, though most of the black oaks I know are much older so there is some difference in their appearance. The reddish buds with their gray pubescence and gray bark with hints of a more yellow inner bark tend to make me think it is Quercus velutina over the other usual suspects like northern red oaks, pin oaks, and scarlet oaks. But again, just a guess for now.
