These two trees are difficult for me to identify, but I hope someone will help: The branch with red blossoms was photographed in New York, Central Park. I believe that these tall trees are quite common in this area, for instance in Philadelphia. The other tree was photographed in a botanical garden in Las Vegas, Nevada, in Springs Preserve. and is the only tree of this kind I have seen. The picture should hav been rotated clockwise to vertical position! Both pictures were taken in April 2014. Grateful for an answer!
Thank you! My questions may seem plain stupid, but I live in Scandinavia, Norway and many American plants are unknown for me. I'm gatefu for this forum and the very quick replies here!
