These new canes are the way the rose renews itself. Sometimes mistaken for the 'sucker' cane which does not emerge from the bud union. The example is of a five-leaflet leaf. Petiole - The tiny stem holding all the leaflets. Petiolul - a subdivision of the petiole that connects a leaflet to the petiole.
Some roses have very smooth leaf margins, others are very deeply 'dentate' or toothed.
