Allium cernuum - Nodding Onion

  • This plant is easy to identify because of the nodding habit of its umbels of flowers. Nodding umbels of flowers are an evolutionary adaptation that tends to restrict insect visitors to bees. Other insects are more reluctant to hang upside down while attempting to feed on nectar or pollen. The nodding habit may also protect the nectar from rain.
