The Sea Rose (Orphium frutescens) grows in sand near the coast. The shiny, bright pink flowers attract large Carpenter Bees that collect pollen in an unusual way called buzz pollination. The bee holds onto the cluster of bright yellow, twisted anthers in the centre of the flower and vibrates its wings for about two seconds, producing a loud buzzing sound. The buzzing causes the pollen inside the anthers to vibrate and shoot out of a pore at the tip of each anther, coating the underside of the bee. When the bee visits another flower, the pollen rubs off on the stigma.
