#1873 - Platanus × acerifolia - London Plane

AKA Platanus × hispanica, or hybrid plane. A very common urban tree in many parts of the world, because of its tolerance for air pollution and soil compaction, and resistance to anthracnose cankers. Unfortunately, in many parts of the world hardly anything will eat it, which doesn’t help biological diversity in the aforementioned cities, and the small stiff hairs shed by young leaves and dispersing seeds are an asthma trigger. 

This was one of many growing around the Melbourne CBD, where my asthma was being well and truly triggered.

It’s believed to be an accidental hybrid of Platanus orientalis (oriental plane) and Platanus occidentalis (American sycamore), but it’s possible that it’s a cultivar of P. orientalis. Either way, the seeds are fertile. 

London Plane is a deciduous tree up to 40 m (131 ft) tall, with a trunk that can be up to 3 m (10 ft) or more in circumference. The bark is usually pale grey-green, smooth and exfoliating, or buff-brown and not exfoliating. The palmate, lobed leaves are thick and stiff-textured, and up to 25cm broad. Unsurprisingly, the leaves can also be a problem once they pile up on roads and sidewalks. 

Some urban birds will pick the seeds out of the seed balls, and the timber is a quite attractive form called ‘lacewood’ but in many parts of the world the trees are being removed and replaced with more ecologically sound choices.

Немного об прошедшем лете. Где здесь верх?
