Things in unusual places: Ginkgo biloba
I've followed this tree up the ramp at Cabot Circus car park in Bristol many times. Its buttery yellowness and being forced to park on the top floor finally persuaded me to take a longer look, much to the annoyance of some motorists. I didn't care. I was 'parked' on a little step and could safely peer my camera over the edge to take this picture.
To my delight I found a Ginkgo biloba. It's surprising a tree can survive being planted in such a space, never mind one of the more unusual ones. Later that day I realised the city centre's street tree planters seem to have a special fondness for this specimen. They're everywhere.
Here's one of several I found later in Broadmead. It's not the first time I've got excited about this species... here's a golden tale from the garden at Bath's Holburne Museum.
