In Ultima Online, the Artisan Festival Tree is a key element of the Artisan Festival event, which takes place annually. During this event, players contribute Bulk Order Deeds (BODs) to elves located in specially decorated areas within various cities. As players turn in BODs, the tree grows in stages, and its growth is indicative of the collective efforts of the community. The more BODs submitted, the larger and more impressive the tree becomes. At the end of the festival, participants are rewarded based on their contributions, with potential gifts ranging from themed holiday items to decorative lanterns and pillows.

The Artisan Festival is celebrated in cities with active Governors and a minimum treasury balance. Players can participate in the event in cities such as Britain, Jhelom, and Minoc, among others. The growth and ultimate completion of the tree result in a festive display, culminating in a gift raffle where rewards are distributed to participants based on the value of the BODs they turned in​
