petioles
Blade-to-branch connectors
Petioles are the slender stalks that attach leaves to the stems of plants.
Each petiole serves as the leaf's structural support and conduit for water and nutrients traveling between stem and leaf blade.
Some plants have notably long petioles, like celery, where the petiole itself is the edible part.
In botanical description, a leaf without a petiole—one that attaches directly to the stem—is called sessile.
