Flowers are predominantly wind pollinated and the original rosette dies after seed maturation, and up to eight new rosettes are produced around the flower stalk base.

The ratings are based on a number of factors including whether the plant is insect or wind pollinated, whether it has large, bright flowers or tiny, off-white or greenish flowers, and the length of its pollen period.

Flowers of wind pollinated plants tend to lack petals and or sepals; typically large amounts of pollen are produced and pollination often occurs early in the growing season before leaves can interfere with the dispersal of the pollen.

The plants are wind pollinated with the male inflorescences in small tassels swaying in the wind, while the female flowers are at the base of medium sized bracts, which catch the pollen from the air and funnel it towards the small fringed styles of the female flowers.

Honeybees also help plants to reduce time between flowering and fruit set, which reduces risk from harmful factors such as pests, diseases, chemicals, weather, etc . Specialist plants that require honeybees will be at more risk if honeybees decline, whereas generalist plants that use other animals as pollinators ( or wind pollinating or self-pollinating ) will suffer less because they have other sources of pollination.
