Poplar Robusta is a hybrid between the Lombardy Poplar and the Eastern Cottonwood of America.
It has large red male catkins in March followed by orangey-red juvenile leaves in April. These appear golden when the sun shines through them, as in the photo.
They soon turn green, effectively masking the maisonette block behind my house until autumn comes round again.
The black blob in the centre of the picture is a wood pigeon.

In a new study published in Ecology Letters, researchers from the Max Planck Institute for Chemical Ecology and the University of Kiel, Germany, report on the influence of an endophytic fungus of the genus Cladosporium on the defense of black poplars against herbivorous insects. The fungus, which lives inside the leaves, not only increases the production of defensive substances in the trees, but also produces an alkaloid itself that protects the trees from feeding damage.
