Celtic Tree Calendar

In Celtic culture, trees play a large part in astrology and the zodiac. Just like with the star signs the tree calendar spans across different months and is aligned to the cycles of the moon. Each lunar month is ruled by its very own UK native tree. This is also tied in with the old Ogham alphabet and each tree has a corresponding letter. Read more about the Celtic Tree Calendar below and find out what your Tree Zodiac is.

The trees that make up the calendar form a part of our Ancient Wisdom Tree Range and they make truly special birthday gifts to send for each month. Many people have never even heard of a tree zodiac and will be delightfully surprised when they find out their sign when they open their gift on their birthday.

Our native trees are the best gifts for the person who has everything, not only that but they are eco-friendly and will last a lifetime. We can’t think of a better reason to send someone a tree on their birthday, can you?
