Crocus tommasinianus often flowers nonstop from late winter through early spring and provides early season bumblebees and honeybees with a much needed source of nectar and pollen.
Bumblebees are one of the few insects that can reach the crocus nectaries found underground at the end of the long flower-tube. Honeybees are unable to reach and collect the nectar with their shorter tongues, thus they collect the pollen.
