The ancient, gnarled tree in Alfama seems to have witnessed countless stories from the neighborhood. With its thick trunk, twisted branches, and the shadows it casts on the cobblestones and house walls, it offers a tranquil counterpoint to the hustle and bustle of the narrow streets. A beautiful spot to pause, take a breath, and soak up the unique atmosphere of old Lisbon.

The former Limoeiro Square, currently a street connecting downtown Lisbon to the Portas do Sol viewpoint, is a must-see for tourists and part of the famous tram line 28. Next to the wall of the former Limoeiro Prison, now the Center for Judicial Studies, stands a Phytolacca dioica L., which replaced the lemon tree from which this square took its name. It is approximately 13 meters tall, 17 meters across its base, and 100 years old. This species is native to South America, has a very fast growth rate, and blooms between April and June.

In a botanical garden, plants are kept looking as close as possible to what they would have in nature, without excessive human intervention (for example, pruning or cutting dry leaves). On the other hand, this ‘hands-off’ option encourages small ecosystems where insects and small animals, other plants, fungi and lichens, which are extremely important for urban biodiversity, live. In the summer, we only water what is essential. Water is a precious commodity, especially in a country like Portugal. Therefore, it is possible that water circulation is limited and that the undergrowth may become drier, especially in the summer. This is a deliberate option that does not put the plants at risk. The presence of the Garden in the heart of Lisbon mitigates the effects of rising temperatures, promoting its own microclimate and the capture of carbon dioxide.
