__ Nectar information __
There was no nectar present in this species. Possible reasons: - Evaporation of the nectar due to a hot day - Hybrid ornamental, therefore may not have been bred to produce a high nectar content - Could have recently been pollinated, therefore nectar all gone

**__Pollen information __** - Bee pollination (biotic) - The perfume increases the presence of pollinators - Bowl shape encourages the insects into the centre of the flower to the pollen - For a Rose it is very abundant in pollen
