Their fall color is typically more often deep maroon to rusty red, though on occasion can be brilliant scarlet tinged, all however turning a dull, light brown later in the season, often persisting until spring bud break (marcescent). "Pin oak" redirects here. Unfortunately this tree suffers greatly from chlorosis (yellowing) of the leaves due to high soil pH. It persists on heavy, wet soils because it produces an abundance of acorns which, if released, grow faster on these sites than most of its competitors.. The acorns require two growing seasons to develop. They share many over lapping characteristics and can be a challenge to distinguish by even well trained foresters. They do not grow on the lowest, most poorly drained sites that may be covered with standing water through much of the growing season. Scarlet oak is an upland species that prefers soils with good drainage on dry sites. Diseases: oak wilt -Little can be done about oak wilt.
Pin oak, either of two species of North American ornamental and timber trees belonging to the red oak group of the genus Quercus in the beech family (Fagaceae). The form and fall color of pin oak make it a popular for ornamental. Prolonged flooding may kill entire stands.
For info on subjects other than plant identification (gardening, invasive species control, edible plants, etc. , Pin oak is classed as intolerant of shade. I'm curious if these trees are exceptions or typical northern red oaks.  The wood is hard and heavy and is used in general construction and for firewood. Their crowns may exceed 40 feet, and they often contain drooping limbs near the base.
1 to 3 female flowers, with bright red styles and a short, stubby, green stalk, sit in the leaf axils of new growth. In fact, roughly the same amount of sinus area exists as actual leaf area. When grown in acidic soil, pin oak can be a handsome specimen tree. The leaves become yellow or pale brown in autumn, often with purple blotches. The form and fall color of pin oak make it a popular for ornamental. , Pin oak is an associated species in silver maple–American elm forests in the bottom lands along the Ohio, Wabash, Mississippi, and Missouri Rivers. Pin oak is utilized by many game species, especially wood ducks, whitetail deer, and wild turkey. Pin oaks grow primarily on level or nearly level, poorly drained, alluvial floodplain and river-bottom soils with high clay content. Overall autumn leaf coloration is generally bronze, though individual leaves may be red for a time, and is not considered particularly distinctive.
The trunk is typically straight up through the crown, only occasionally developing a double leader.
Pin oak is one of the most commonly used landscaping oaks in its native range due to its ease of transplant, relatively fast growth, and pollution tolerance.
Lower branches on a pin oak will require removal when used as a street or parking lot tree as they tend to droop and hang on the tree. Pin oak is among the most widely planted native oaks in the urban landscape, the third most common street tree in New York City. The Insect Table provides a more complete list of species that feed on oaks.

While most common in moist, bottomland sites, such as flood plains and along the edges of swamps, pin oaks are tolerant of a range of soil conditions. Bark on mature trees is dark brown to gray with blocky ridges and moderate to deep vertical furrows. Pin Oak develops nicely on moist, acid soils and is tolerant of compaction, wet soil, and urban conditions. The level topography and presence of a claypan in the soil of these areas cause these sites to be excessively wet in winter and spring.. Young trees have a straight, columnar trunk with smooth bark and a pyramidal canopy. The bark was used by some Native American tribes to make a drink for treatment of intestinal pain. ), please check the links and invasive species pages for additional resources. In the bright sunshine, the verdant green leaves were strikingly shiny and attractive. Attributes Has a distinctive branching pattern that sets it apart, especially in winter. Each side has 2 to 4 primary, finger-like lobes, each with 2 to 5, sharply pointed secondary lobes at their tips. Note: All comments are moderated before posting to keep the riff-raff out.

Provides great fall color, with leaves turning shades of scarlet and bronze. It is less tolerant than elm, boxelder (Acer negundo), sweetgum, hackberry (Celtis occidentalis), and ash, but is more tolerant than eastern cottonwood and black willow. Due to similarity in leaf shape, the pin oak is often confused with scarlet oak and black oak, and occasionally, red oak. , Pin oak is a major species in only one forest cover type, pin oak–sweetgum, which is found on bottom lands and some upland sites throughout the central portion of the pin oak range. Its distinctive shape is considered unique among hardwoods. In closed canopy forests it is tall and straight with few or no lower branches, but in more open areas, lower branches grow downward creating a large round crown, often close to the ground. Upon a closer inspection, the rather petite leaves had rounded deep sinuses and lobes that were quite spiny. This branch angle can make the tree unmanageable in close urban settings. It is very sensitive to soil pH above the high 6’s. Pick an image for a larger view. Black Oak acorns also tend to be rounder and the cap typically covers 50% or more of the nut. Another interesting group of insects are gall wasps, which often form various kinds of galls on the leaves or twigs of oaks. Uses: large parking lot islands; wide tree lawns; recommended for buffer strips around parking lots or for median strip plantings in the highway; tree has been successfully grown in urban areas where air pollution, poor drainage, compacted soil, and/or drought are common. Buds; clusters of pointed buds located at tips of twigs. There are Q. alba and macrocarpa but they are not as old. See the glossary for icon descriptions. However, graft incompatibility often leads to future trunk failure on these cultivars. Insect: Gypsy moth should be controlled when the trees are young, but older trees can tolerate infrequent defoliation. Funding provided by the Minnesota Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources. Spurlike, slender branchlets stand out like pins on the trunk and larger limbs. , A characteristic shared by a few other oak species, and also some beeches and hornbeams, is the retention of leaves through the winter on juvenile trees, a natural phenomenon referred to as marcescence. In its native range, pin oak is the most commonly used landscaping oak along with northern red oak due to its ease of transplant, relatively fast growth, and pollution tolerance. Some examples of species in this group include Amphibolips confluenta (Large Oak Apple Gall Wasp), Callirhytis cornigera (Horned Oak Gall Wasp), and Callirhytis quercuspunctata (Gouty Gall Wasp). Also, since the bark of pin oak is relatively thin, the species is especially susceptible to damage by fire and decay associated with fire wounds..
Intermediate and suppressed trees in such stands usually die within a few years of being overtopped. emerge soon after new leaves unfold in spring (April to mid-May).

These cultivars are thought to be better suited than the natural species as street and parking lot trees. Pin Oak develops nicely on moist, acid soils and is tolerant of compaction, wet soil, and urban conditions. The leaf is mostly hairless, except for a very characteristic tuft of pale orange-brown down on the lower surface where each lobe vein joins the central vein. Pin oaks have deeply lobed, bristle-tipped leaves that usually turn red or brown as autumn approaches. And no, it does not root sucker. Pin Oak grows well in areas where water stands for several weeks at a time.
The trees can usually survive one growing season of continuous flooding, but will be killed by continuous flooding over 2 or 3 consecutive years. They are usually found on sites that flood intermittently during the dormant season, but do not ordinarily flood during the growing season. Young trees under 6 m (20 ft) are often covered with leaves year-round, though the leaves die in the fall, remaining attached to the shoots until the new leaves appear in the spring.

Most people find red oak acorns to be bitter and unpalatable.
Pin oaks are part of the red-oak group, and, as with all other red oaks, their acorns take two years to reach maturity. The lower branches on pin oak cultivars ‘Crown Right’ and ‘Sovereign’ do not grow down at a 45-degree angle as does the non-cultivar. Quercus palustris, the pin oak or swamp Spanish oak, is an oak in the red oak section (Quercus sect. The usual lifespan of an oak is about 200 years, but some live over 1,000 years. Pin oaks are medium-sized oaks that reach up to 70 feet in height. Large areas of almost pure pin oak occur on the "pin oak flats" of the upland glacial till plains or in the bottom lands of the lower Ohio and central Mississippi River valleys. Pin oaks have a pyramidal growth form while they are young, although their crowns become rounded or oval in shape upon maturation. Pin oaks are part of the red-oak group, and, as with all other red oaks, their acorns take two years to reach maturity. Q. palustris is mainly distributed in the eastern and central United States from Connecticut west to eastern Kansas, and south to Georgia, west to eastern Oklahoma and Kansas.
The flowers are monoecious catkins which, being self-incompatible, require the presence of another oak for pollination. A 10-year-old tree grown in full sun will be about 8 m (26 ft) tall. The pin oak is also well adapted to life in Australia (where it has been introduced), and is quite widespread across the Australian continent, especially in the cooler southern States such as Victoria and New South Wales. It is also well adapted to life in South Africa and Argentina, especially in the Río de la Plata region. The acorn is unpalatable because the kernel is very bitter. Plant trees in a slightly raised mound or bed if the soil is poorly drained. Each lobe has five to seven bristle-tipped teeth.
of the tree are often available.
It is a great tree for large landscapes, but its hanging lower branches make it a high … deciduous, but usually persisting on into winter. It is water tolerant and is native to stream banks and flood plains. This tree grows under a wide range of site conditions, but is a true bottomland tree.
The stump from the tree has over 200 growth rings. Some of the interesting facts about oak trees are listed below. I was quite pleased to recognize that these trees were nice specimens of the upper Midwestern endemic, Northern Pin Oak.
I'm currently considering adding the Northern Pin Oak to my landscape.
