In the Sept/Oct issue
of City Trees, we will
put the spotlight on
Magali Duzant's sublime
book, A Tree Grows in
Queens (2024, Conveyor
Editions). She says, "The book is a
meditation on the many ways in which
trees manifest into other forms—from
myths and memorials to meeting points
and harbingers of luck. It is structured
as a collection of essays and images; the
photographs, in exhibition format, are
presented as overlaid installations."
