A pseudanthium is a type of inflorescence where a group of individual flowers are arranged in a cluster, giving the appearance of a single flower. The advantage of having a pseudanthium is that it increases the chances of pollination, as the large cluster of flowers attracts more pollinators, such as bees and butterflies, than a single flower would. Additionally, having multiple flowers in close proximity increases the efficiency of pollination, as the likelihood of pollen being transferred from one flower to another is greater. Pseudanthia also often have a longer blooming period, allowing for a longer time period for pollination to occur.
