Taiwan's 'umbrella trees' offer natural shade solution

In Taiwan, a debate over whether to "plant trees or plant umbrellas" for urban shade has sparked discussion. However, the Tianwei Highway Garden in Changhua County offers a unique, natural answer with its two 30-year-old "umbrella trees."

The two trees, a Bougainvillea and a Ficus, have been meticulously pruned into a canopy shape, creating a natural, expansive shade similar to a large umbrella. Located at the garden's entrance, these trees provide a cool respite for visitors, offering shade from the summer sun and becoming a favored resting spot. They are particularly appreciated by those waiting at traffic lights or seeking refuge from the heat.

According to Tianwei Township Mayor Xu Shumei, these umbrella trees are over 30 years old and were donated by local businesses during the reconstruction of the former Yixin Garden. Their distinctive shape not only enhances the landscape but also serves a crucial function in providing shade. Their value is estimated to exceed $300,000 NTD (approximately $9,000 USD), and they have become a significant landmark in the Highway Garden.

Maintaining these natural umbrellas requires consistent care. The trees need pruning every three to four months, a process that involves using a crane and professional horticulturalists. Each pruning session, along with waste disposal, costs at least $50,000 NTD (approximately $1,500 USD), leading to an annual maintenance budget of around $200,000 NTD (approximately $6,000 USD), entirely funded by the township office.

Mayor Xu believes there is no single correct answer to the "trees vs. umbrellas" debate. She emphasizes that the best approach depends on the specific needs of the location. While artificial umbrellas offer quick installation and mobility, planting trees requires careful consideration of drainage, root systems, underground utilities, typhoon-resistant pruning, and ongoing maintenance, all of which incur costs. "The key is not whether to plant trees or umbrellas, but to plant the right trees in the right place" to effectively reduce temperature and provide shade, she stated.
