Carpinus betulus fastigiata
Well known deciduous tree - highly distinctive with a kind of tear-drop shape. It can grow to 35ft after 35 years. Good for formal planting - avenues, rows and matrices (plural of matrix). You'll spot these in urban planting because of the shape whether in the summer or the winter but they're probably most frequently noticed in the autumn when they go a uniform yellow all over. They really stand out in the autumn. Any old soil but they need space to show off their shape.
Fine specimens hiding the Cascades Shopping Centre from the A3 in the middle of Portsmouth on the way to the Isle of Wight Ferry terminal.
The name Hornbeam is derived from the fact the timber is exceptionally hard and hard wearing. Traditionally, it was used for the replaceable teeth on timber cog wheels used in wind and water mills. Many years ago, I was a cabinet maker and used to buy timber from Agates in Horsham. I once asked Wally (the mill foreman) what this little known timber called Hornbeam was like. He gave the memorable and accurate reply : "It's like f***in' 'ard beech mate".
