Spiralvine

This enormous flower grows up to 11.2 feet (3.4 meters) tall. Its orange-yellow stem is thick and straight, and the tiny, yellow-green leaves are very thin with wavy edges. The leaves alternate on the stem from the base up to about halfway.

Each stem splits 3 to 5 times; a single large flower grows at the end of each split. The flowers are 107 cm (42.1 inches) wide, with petals that are generally crimson; each flower tends to be a variation of this colour. The flower head is largely flat with several tightly layered narrow petals. They fall easily.

It has a delicate scent that smells like onion, and it has an average amount of pollen. It is a self-pollinator, but is also visited by one species of insect in particular.
