With the term fastigiato in botany, we mean a tree that has a crown with a conical conformation.
The term fastigiato derives from fastigium, in turn coming from the Latin fastigium ‘narrowing, top’.
The term fastigiato, therefore, refers to the posture of a tree with a characteristically conical crown, formed by branches of more or less the same length, closely close to the stem, therefore with an erect and columnar posture.
Classical examples of fastigiato habit are found in some plants of the, such as the cypress poplar (Populus nigra L. var. Italica Moench).
