The Coast Redwood of the Botanical Garden

The tallest tree species on Earth has a foothold in a four-hectare university garden in Porto, and it's already one of the biggest specimens the city has. This coast redwood, native to a narrow fog belt along the California and southern Oregon coastline where mature wild trees exceed 100 metres, is nowhere near that scale here, but the Jardim Botânico do Porto's own description lists it among the largest sequoias documented in the city. Coast redwoods reached European botanical collections in the mid-19th century, decades after their first scientific description, and gardens across Britain, France and the Iberian Peninsula planted them as living proof of the New World's most extreme trees, with no clear sense yet of how they'd perform in a climate so different from California's summer fog. This one has thrived well enough that its crown is now a genuine landmark within the garden's skyline, visible above the surrounding conifer collection from most approaches. The species can reproduce from stump sprouts as well as seed, meaning a felled coast redwood can regrow from its own base, a trait almost no other conifer shares. Porto's specimen has needed no such resilience yet. It has simply grown, steadily, since whichever year in the garden's history someone planted a California seedling in Portuguese soil and hoped for the best.
