Petiole (botany)
In botany, the petiole is the stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the...

s of the leaves may extend as much as 2 m (6.6 ft) and end in a round leaf blade 33–43 cm (13–16.9 in) in diameter. Mature plants range in height from 0.8 to 1.5 m (2.6 to 4.9 ft).

Flowering begins in late spring and may continue into the summer. The specific name means "yellow" in Latin
