Wild daffodils differ from their standard garden counteparts by being smaller, and having paler petals surrounding the yellow crown.
Nectar is produced at the base of the flower tube and is reached by long-tongued bees, which touch the stigma before the stamens, thus pollinating the plant. The bulbs are formed from the swollen bases of the leaves of the previous year (hence why it is best to dead-head garden daffodils, so that the plant's energy goes towards the leaves instead of developing seeds). Both bulbs and leaves are poisonous, thus are avoided by grazing animals.
