It really likes to grow in woodsy places or at the edges of thickets, often along roadcuts or highway banks.
It can be useful for flower identification or comparison between angiosperm taxa. Paleontologists can take advantage of diagrams for reconstruction of fossil flowers. Floral diagrams are also of didactic value. [1]: xiii Relation of a plant material (Campanula medium) to the floral diagram. Black dashed line shows the cross-section. 1 ...
