Quercus robur, also known as common oak or English oak, is a species of tree in the beech and oak family. The leaves of this tree are green in summer and turn brown or red in autumn before falling off. In winter, the leaves stay on the tree, providing shelter for birds and small animals.
Most oak trees are deciduous, meaning they lose their leaves in the fall. But there are a few species of oak tree that keep their foliage all winter long. These “evergreen oaks” are native to warm climates like the Mediterranean and Southern California.
One of the most common evergreen oaks is the holm oak (Quercus ilex). This tree is often used as an ornamental plant in colder areas because it doesn’t lose its leaves in winter. The holm oak has dark green, leathery leaves that stay on the tree all year round.
Another popular evergreen oak is the live oak (Quercus virginiana). This species is native to the southeastern United States, where it’s a common sight in coastal regions. The live oak has long, narrow leaves that remain on the tree throughout winter.
If you’re looking for an evergreen oak to plant in your garden, make sure to choose a species that’s suitable for your climate. Evergreen oaks need full sun and well-drained soil to thrive. With proper care, these trees can provide years of beauty and enjoyment!

Winter Gardening Planting Oak Trees
What Oak Trees Hold Their Leaves in Winter?
Oak trees are deciduous, meaning they lose their leaves in the fall. However, some oak species retain their leaves throughout the winter months. These include evergreen oaks and live oaks.
Evergreen oaks, such as the holm oak (Quercus ilex), keep their leaves year-round. This is an adaptation to Mediterranean climates, where winters are relatively mild and rainfall is scarce. The holm oak’s leathery, dark green leaves are well-suited to drought conditions; they can remain on the tree for up to three years before falling off.
Live oaks (Quercus virginiana), which are native to the southeastern United States, also hold onto their leaves in winter. Live oaks have a high tolerance for salt spray and strong winds, making them ideal trees for coastal regions. Their broad, heavy limbs can support large amounts of Spanish moss (Tillandsia usneoides), a common epiphyte in the southeastern United States.
Do Oak Trees Have Leaves in Winter?
Oak trees are deciduous, meaning they lose their leaves in the fall and grow new ones in the spring. So, yes, oak trees have leaves in winter…they just don’t have any!
Why Do Some Oak Trees Keep Their Leaves All Winter?
When most people think of oak trees, they picture the classic image of a massive tree with thick, sturdy branches and leaves that change color in autumn before falling off. However, not all oak trees follow this pattern. In fact, some oak species keep their leaves all winter long.
There are several reasons why an oak tree might retain its leaves through the winter months. One possibility is that the tree is trying to conserve energy. Shedding leaves requires a lot of energy, and by keeping its leaves, the tree can put that energy into other things like growing new roots or producing more fruit.
Another reason could be that the tree is trying to protect itself from damage. Leaves are full of nutrients and water, which can be vital for a tree’s survival during the winter when food is scarce. By keeping its leaves, the tree can make sure it has enough resources to make it through until springtime.
Finally, it’s also possible that the tree simply hasn’t gotten around to shedding its leaves yet! This is especially common in young trees or trees that are stressed due to disease or environmental conditions.
Whatever the reason, seeing an evergreen oak tree in the middle of winter is a beautiful sight – and a reminder that nature always has something new to surprise us with.
Which Trees Keep Their Leaves in Winter?
There are many trees that keep their leaves in winter, including evergreens, hollies, and boxwoods. While some deciduous trees lose their leaves to conserve water or because of the cold weather, these three types of trees have adapted to maintain their foliage year-round.
Evergreens, as their name suggests, have green leaves all year long.
This is because they have a waxy coating on their needles that prevents moisture loss. In addition, evergreen trees typically have shallow root systems that allow them to absorb water from melting snow. Hollies also keep their leaves in winter, which is helpful for providing birds with food and shelter during the colder months.
Boxwoods are another type of tree that doesn’t lose its leaves in winter. This is due to the fact that they produce a chemical called “abscisic acid” which helps them tolerate freezing temperatures.

Do Red Oak Trees Lose Their Leaves in Winter
It’s that time of year again! The leaves are changing color and falling off the trees. For some, this is a sign of the impending winter.
But what about the trees? Do they lose their leaves in winter too?
The answer is yes, red oak trees do lose their leaves in winter.
However, they don’t always lose all of their leaves. Sometimes, only the outermost layer of leaves will fall off, leaving the inner layers intact. This helps to protect the tree from cold weather and wind damage.
When the leaves do fall off, they usually turn brown or reddish-brown in color before falling to the ground. Once on the ground, they’ll eventually decompose and become part of the soil. This process provides nutrients for new plants to grow in springtime.
So if you see red oak trees with bare branches in winter, don’t worry! They’re just getting ready for a long winter’s nap.
Conclusion
If you’re wondering which oak trees keep their leaves in winter, the answer may surprise you. While most oaks lose their leaves in autumn, there are a few species that retain their foliage throughout the colder months. Evergreen oaks are more common in warmer climates, but they can also be found in temperate regions.
Some of the most popular evergreen oak varieties include the holly-leaved oak (Quercus ilex), the cork oak (Quercus suber), and the holm oak (Quercus rotundifolia). These trees are all native to southern Europe and North Africa, where winters are relatively mild. However, they can also tolerate cooler temperatures and even light frost.
While evergreen oaks are not as common in North America, there are a few species that grow here as well. The live oak (Quercus virginiana) is perhaps the best-known example. This massive tree is native to the southeastern United States and can reach heights of over 60 feet (18 meters).
It has dark green leaves that stay on the tree all year long.
So, if you’re looking for an oak tree that will keep its leaves during wintertime, look no further than these three species.
