The live tree is expected to be illuminated in time for Black Friday, marking a notable shift in one of the city's most visible holiday traditions. The reason for the change was not immediately clear, and city officials did not elaborate on the decision.

A Macy's spokesperson said the retailer will continue to offer holiday programming, including gifts, special experiences and the SPCA holiday windows, without directly addressing the switch to a live tree.

Marisa Rodriguez, of the Union Square Alliance, welcomed the change. "I am thrilled to welcome a live tree for the first time in over 20 years this holiday season in Union Square," she said, adding that the community is grateful to Macy's for its support of the holiday season.

The city said it remains committed to keeping the Union Square holiday tradition alive by investing in vibrant seasonal experiences. Officials said the goal is to bring joy to residents and visitors while supporting local businesses and driving economic activity downtown.

For some residents, the switch from artificial to real matters less than the gathering space the tree provides. "For me, as long as there is somewhere for people to congregate and enjoy the city, I love it," said Rawshawn, a local resident. "I'm not sure what the move was to go to an actual tree, but for as long as there is somewhere to go for all the kids to come and play."

The tree's arrival comes as downtown San Francisco continues to seek ways to draw foot traffic and support small businesses during the crucial holiday shopping period. Union Square has long served as the centerpiece of the city's seasonal celebrations, and the annual tree lighting has been a draw for residents and tourists alike.
