What is the oldest tree in Porto?

A Virginia tulip tree beside Casa Tait in the Jardins do Palácio de Cristal, over 250 years old and individually protected since 1950, one of Portugal's earliest such classifications.

Are Porto's remarkable trees free to visit?

Nearly all of them. Seventeen of the twenty-seven stand in free public gardens or walkable university campuses: the Jardins do Palácio de Cristal, the Jardim Botânico do Porto, the Jardim da Cordoaria, and three University of Porto quintas a short walk further east. The one exception is the Camphor Tree of Via Panorâmica, which stands on a privately owned plot and is viewed from the public road rather than entered.

Why is Porto called the City of Camellias?

Camellias, introduced from China and Japan in the 18th and 19th centuries, thrived so well in Porto's mild, humid climate that Portuguese growers began exporting specimens back to camellia breeders elsewhere in Europe. Casa Tait's own century-old camellia hedges, inside the Palácio de Cristal gardens, are among the oldest surviving examples in the city.

Why do so many of Porto's remarkable trees grow in the same handful of gardens?

The Jardins do Palácio de Cristal, the Jardim Botânico do Porto, and the University of Porto quintas further east (Casa Primo Madeira, the FAUP campus, Palacete Burmester) all began as private 19th-century estates belonging to wealthy families, several with ties to the port wine trade, who competed to plant the most impressive imported specimens. Nearly all later passed into public or university ownership, keeping their tree collections intact and mostly freely accessible.

Porto's grandest trees mostly arrived with 19th-century British port wine families, who filled their quintas with tulip trees, magnolias and southern hemisphere exotics their money could import but Porto's own climate had to accept. Three gardens hold much of what is worth seeing: the Jardins do Palácio de Cristal, the Jardim Botânico do Porto, and the Jardim da Cordoaria, near São Bento station. A short walk east adds three University of Porto quintas, the same collector's habit continued on academic ground. Porto also calls itself the City of Camellias, and means it literally.

The Tulip Tree of Casa Tait

Tulip Tree (Liriodendron tulipifera) · 250+ years · Massarelos

This American tulip tree became one of Portugal's first individually protected trees in 1950, a legal status most of the country's current laws postdate. It grows beside Casa Tait, a 19th-century mansion inside the Jardins do Palácio de Cristal that once belonged to a British port wine family, and at more than 250 years old it predates both the mansion and the palace gardens built around it by a century or more. Liriodendron tulipifera is native to the eastern United States, named for the yellow-green, cup-shaped flowers it produces each late spring, blooms that only appear once a tree reaches real maturity and can go unnoticed entirely on a younger specimen. A second tulip tree grows nearby in the same grounds, over 40 metres tall, though it lacks this one's formal protection status and shouldn't be confused with it. Porto's oldest tulip tree survived the transformation of its surrounding grounds more than once: the Palácio de Cristal itself, the glass-and-iron exhibition hall that gave the gardens their name, was demolished in 1951 and replaced by the domed sports arena still standing today, a change that came one year after this tree's own protection was made permanent. Whatever else has come and gone around it, the tulip tree has stayed exactly where it was planted.
