Many people call them mountain-ashes because their leaves look like ash trees. However, they are not true ash trees at all. True ash trees belong to a different family called Oleaceae. Rowans are easy to tell apart if you look closely at their leaves. Rowan leaves grow in an alternate pattern along the stem. This is different from true ash leaves, which grow in opposite pairs.

Watching a rowan grow is a wonderful way to see nature work. In the spring, the tree produces creamy white flowers. These flowers grow in dense groups called corymbs. Each flower has five petals and a cross shape. After the flowers bloom, the tree grows small fruits called pomes.

A pome is a type of fruit similar to an apple. Most rowan fruits are bright orange or red. Some species in Asia have pink, yellow, or even white fruit.

These fruits are soft and very juicy. They serve as a great food for many birds. Birds like waxwings and thrushes eat the fruit. As they eat, they spread the seeds through their droppings. This helps new rowan trees grow in new places.

People have studied and named these trees for a very long time. The name rowan has been used since at least 1804. It might come from old words meaning "to redden." This describes the bright color of the berries.

In the 1500s, an English herbalist named John Gerard wrote about them. He actually made a mistake and confused them with other trees. Many different names for the tree exist in different languages. In Welsh, the names can mean "the lamenting fruit." In Scotland, the name is used in many place names. Even the letter "R" in old books is linked to the rowan.

There are many interesting facts about how we use rowans. The wood of the tree is very dense and strong.

People use this wood for carving and making tool handles. It is also good for making walking sticks. In Finland, people used the wood for horse sled shafts. The fruit can be used to make jelly or jams.

You must cook the fruit to make it safe. Raw fruit contains a substance that can cause stomach pain. Heat treatment changes the fruit into something safe to eat. Some people even use the fruit to make special drinks. In Austria, they make a clear drink called Vogelbeerschnaps.

Rowans are also part of many old stories and legends. In Norse mythology, the tree is called the "salvation of Thor." This is because the god Thor once saved himself by clinging to one.

In Irish myths, a famous couple once climbed a magical rowan tree. They ate the sweet berries while hiding from a giant. Many cultures also thought the tree was magical and could give protection. In the Highlands, people had strict rules about using the tree. They often only used the berries for special rituals. Today, many people plant rowans in their gardens as ornamental trees. They are beautiful to look at and help local wildlife thrive.
