Horse chestnut trees were in full bloom in many cities. They are planted as avenue trees. White and pink varieties were seen.
Are these Aesculus hippocastanum? Both white and pink?

Attaching some additional pics of the tree and the fruit. Kindly validate. Attachments (6)

This might be a hybrid with A. indica – see: http://www.forestry.gov.uk/forestry/infd-74sj7v for some useful information.
