It is necessary to pollinate some commercially grown crops, such as vanilla beans, passion fruit, and date palm. It is considered that nectar-loving bees may play a role in pollination since they like nectar. To create a new plant, genetic information is transmitted through seeds. Phleum pratense is a tufted or single-stemmed, short-lived, cool-season perennial grass that grows in stools or clumps, reaching up to 150 cm in height.
