Platanus orientalis is found especially in southern Europe (Sicily, Greece). In general, their range is huge. It is found in the Middle East, Central Asia and even in the Himalayan region.
It reaches growth heights of up to 30 meters and is often used as a street tree. The trunk can become so extensive that in the Middle East even rooms are built into it. The crown of the tree can become very sprawling.
The flowering period is in May. Pollination occurs through the wind.
Oriental plane trees can excellently cope with heat and drought. They do not tolerate waterlogging of any kind. Platanus orientalis likes full sun and is a classic light tree. It is considered sufficiently frost-hardy and can therefore thrive in Central Europe. Genrell it is also considered a very wind-resistant tree. See also: https://de.wikipedia.org/wiki/Morgenl%C3%A4ndische_Platane.
The wood of the oriental plane tree is considered to be vulnerable outdoors and is therefore more commonly used indoors.
Meanwhile, the Ortientplatane is increasingly used in non-native forests due to its climate resistance. The flaking bark provides shelter for many insects. It also protects other trees with its storm resistance. Due to its spreading branches, it provides shade for soils and prevents them from drying out.
It copes with almost all soils.
Probably the most famous Oriental plane tree is the “plane tree of Hippocrates” on the Greek island of Kos. According to legend, it was planted by Hippocrates himself. Later he taught his students under the tree. However, the plane tree should be “only” about 500 years old. It has been a natural monument since 1985.
For germination of seeds is recommended to first put them in a water bath for 24 hours. Then they go into a damp (not wet, not dripping) mixture of earth and sand. Optimal is to cool this 90 (!!) days, if necessary, they can be placed outside for a few nights (in frost). It is recommended to always check if they germinate. After the procedure: In the spring, put in plant pots and grow in a sunny place. However, be careful: young seedlings need slightly shady places in midsummer.

Quercus cerris grows up to 200 years old and reaches heights of up to 35 meters. The trunk grows up to 2 meters thick.
The acorns ripen relatively early (September to October) and grow up to 3 cm long. They usually sit in a spiny cupule. Originally they are found in southern France, southeastern Europe (e.g. Albania, Bulgaria) and Italy. Through artificial plantings also exist many specimens in England, New Zealand and Argentina. In Central Europe, this tree species is a common park tree. In southern Europe it is one of the most common forest trees.
The leaves are dark green in summer and turn yellowish or reddish in autumn. It is considered to be resistant to urban climates. The flowers of the cercia are green-red. The flowering period is from April to May. As a deciduous tree, it loses its leaves in winter.
As a site, this oak species prefers warm and nutrient-rich soils. It grows on both calcareous and acidic silicate rock. Nevertheless, the distorting oak likes it best alkaline. The more calcareous the soil substrate, the better it tolerates drought. However, dry sandy soils are an exclusion criterion. The wood is very suitable for building (e.g. for railroad sleepers) or also as firewood. The acorns are often used as pig feed. The juice that comes out after bark injury can be made into syrup and used as a sugar substitute. Quercus cerris is very robust against wind and heat. Even air pollution and road salt do not seem to bother her. It is also quite resistant to pests. Oak processionary moth or oak splitting beetle have it with this plant heavy.

When young, Quercus cerris grows up to 30 cm per year.
In the current “temperate” zones, the cedar is considered the tree of the future against global warming. It tolerates two to three months of summer drought. Very well it can be grown as a pot plant (in very deep pots), moreover, it is very frost hardy. It tolerates temperatures down to – 20 degrees.

This species does not yet have a unique name. The botanist who discovered this species has yet to publish a scientific paper on it. Similar to Quercus miquihanensis. This would mean that it would be a species similar to the one found in Mexico.
The acorns come from a harvest of September 2023 in the south of France.

Quercus illicifolia (scrub oak) is native to the northeastern and southeastern United States and Canada, respectively. It grows up to 7 meters tall. Its inner pinkish bark is striking. The leaves take on a yellow or reddish-brown color in the fall. The length of the leaves is between 5 and 12 cm. The acorns are roundish and very small (about 1 cm).
The annual growth of Quercus illicifolia is very low. This species likes sandy or stony soils. Originally it is often found in the mountains. In its native habitat, this species is a helpful component of the autumn diet of black bears. The Iroquois use the acorns for gynecological problems.

Quercus heterophylla (Variegated Oak, Bartram’s Oak) is originally from the USA (eastern range). It is a hybrid of Quercus robur and Quercus phellos. In the Netherlands, one tree of this species is known, which has a trunk circumference of 4 meters. Maximum heights of this tree are 26 meters.
See: https://www.monumentaltrees.com/de/baeume/quercusxheterophylla/rekorde/.
Leaves are oval, elliptic, oblong to lanceolate, smooth-edged to coarsely toothed, glossy green, 8-18 cm long. In autumn, these turn red. The upper side is shiny green and bare. The underside is lighter and hairy only in the vein axils. Quercus heterophylla is very frost hardy (to -23 degrees) and tolerates road salt. That is why this tree is found sporadically in Europe as an avenue tree. This species also tolerates wet and poor soils, provided that they are not too calcareous. Tend to the soil should be rich in nutrients and slightly acidic. Overall, this tree species is tolerant of different soil types: Loess, clay, peaty soil, light clover soil, sandy soil, loamy
Soil.
The tree sheds only a few acorns, these have a similar appearance to Quercus rubra.
Quercus saltillensis is originally found in Mexico. Their striped acorns are particularly impressive. These are relatively small (usually at about 7 mm).
The species is climate warming resistant. It occurs mainly at high altitudes between 1900 and 2500 meters. The tree grows up to 5 meters high.

Quercus depressa belongs to the red oaks.
Bur oak (Quercus macrocarpa ) is originally from northeastern America and is considered to be a “settler”. It now grows in Alaska and Canada as well as in the southern United States.
It was first mentioned botanically in 1811.
It is very heat and drought resistant and as a candidate tree against the consequences of global warming in urban areas of Europe (occurs there so far still very rarely).
The burr oak grows up to 50 meters high and reaches trunk girths of up to 3.5 meters. Their growth is relatively slow (30 cm). It is interesting to note that the more northerly the acorns occur, the smaller they become. If they reach diameters of up to 6 cm in southern climes, they are often conspicuously small in the north. The name “Macrocarpa” (= large fruit) refers to the sometimes huge acorns.
The tannic acid content of acorns is relatively low. The smaller the acorns, the sweeter they taste. Thus, the burr oak is one of the few acorns that are edible. They can be easily fried and eaten and are considered a delicacy in some areas of the United States.
The taproot of the Bur oak is considered fast growing and reaches depths of up to 1.5 meters after only two years. The oak species lives up to 400 years. The leaves can grow very large (15 cm long and 5 cm wide) and have a leathery appearance. Due to its very thick bark, this oak species is even (somewhat) resistant to forest fire.
Optimal for the Bur oak are weakly acidic soils. The tree is also considered suitable for urban climates, but grows very sprawling in width. Sunny sites this tree, like most oak species, likes very much, shade sites are not suitable. The tree is sometimes even described as very resistant to the effects of road salt, see e.g. https://www.angelbachtal.de/dr/bur-eiche-grossfruchtigeeiche.
The wood is thick, tough, heavy and durable. It is one of the most valuable barrel and furniture woods. In addition, it is also used in construction for flooring and the like.

Quercus petraea (the Sessile Oak, also known as the Winter Oak) reaches growth heights of up to 40 meters and trunk girths of up to 2 meters. It can live up to 1000 years.
Acorns ripen from September to October and grow up to 2.5 cm long. They grow in a kind of “cluster” (hence the name sessile oak). The bark of this oak species is smooth when young. A thick, deeply longitudinally fissured, gray-brown bark develops with age.
This species of oak is often found in slightly mountainous areas, it seems to especially like sunny slopes. It is found in many European countries (from Italy to Scandinavia). It is found especially on stony and clay soils; likewise on nutrient-poor soils. However, it does not like waterlogging and too much moisture. It is considered storm-resistant and can penetrate soil layers that are poor in oxygen. In sub-Mediterranean climates, it forms mixed forests with downy oak and Turkey oak. Evidence shows that it has been present in Europe for about 10 million years.
Quercus petraea is relatively drought resistant and is more likely to survive climate warming than the English oak. It is considered to be very heat-loving. It is also considered (in Europe) to be tolerant of heat, drought, emissions and salt. For these reasons, it is also often planted in urban areas. Sessile oaks sprout very early in the year and their leaves can still be found late in the season.
The acorns have a high starch content (almost 40%) but are very bitter without specific water treatment (flushing). However, in principle, they are suitable for an acorn coffee.
Originally, they were used especially for fattening pigs (even before the use of wood). The wood is readily used for construction activities or even wine barrels. In Central Europe, the sessile oak provides a home for up to 500 insect species.
In medicine, the sessile oak is widely used because it is very rich in tannins. Pieces of bark used to be placed on wounds and injuries because they prevent inflammation and stop bleeding. Oak tea of this type is also used against liver disorders and diarrhea.
