What a great photo.

• Who did that topiary? 
• What year was this taken? 
• Who took this photo?

 Topiary in Starcross
Starcross once had some more topiary - there was a row of conical Yew trees along The Strand. see bottom right picture on this postcard

 
and here's another view of them; with people in Victorian clothing.

and here's 3 Francis Frith postcards which also show the Yew trees along The Strand
