🍃 What exactly is a Blattstiel?

Der Blattstiel (Latin: Petiolus; English: petiole or leafstalk) is the part of a plant that connects the Blattspreite (the flat part of the leaf, the leaf blade) to the Stängel (stem) or Zweig (branch). It serves to position the leaf for optimal light absorption and transports water and nutrients.

It is a specific botanical term. In German, the word is masculine, hence der Blattstiel.
