I son't know for sure but I think they might collect pollen from flowers you cut somewhere else and bring in. It might be worth an experiment to see. Earlier this spring I saw my bees bringing in pollen before it was warm enough for flowers to start growing. I assume they were getting some of last years pollen off of the dead plants from last fall.
My question for you is: If you are in such a desert that there are no flowers for pollen collection, how do you have enough nectar to maintain your hives?
