Bignoniaceae
Bignonia Family
Campsis radicans
Catalpa speciosa
Catalpa (Catalpa bignonioides).
Also known in Pittsburgh as “Indian stogie” for its
long, cigar-like seedpods. The combination of pyramids
of white flowers and large, heart-shaped leaves marks
the tree unmistakably as a Catalpa. This is
very much an urban tree, planted originally as an
ornamental, but now a very common weed tree in the
city. It rapidly becomes less common as we get further
out into the suburbs, and is completely unknown in
Butler and Indiana Counties (where, however, the
Northern Catalpa is sometimes
seen).
