At the base of the rhizome are young buds – the growth (vegetative).

Kidney reproductive organs begin to develop when regrowth of plants, forming a flower stalk and seeds. From vegetative buds remains dormant. Each one repeats approximately the development cycle: 12-year – vegetative growth 2nd or 3rd seed formation and death.

Leaves on long petioles, lush, green, pink or red, collected in the outlet. Leaf blade is solid, with a wavy edge, oval or triangular in shape, reaching a size of 70 by 80 inches, especially in wet years.
