Mason bees & growing other Sunflowers

I have a small population of mason bees that will be introduced into my garden this spring. Will this skew the data? I also had planned to grow heirloom helianthus annuus - will this be a problem?

Bees and other Helianthus

Please do grow your garden as usual and congratulations on the mason bees. One of the wonderful things about the project is that by having many different types of gardens and participants, we'll begin to learn about what the best techniques are for gardening for bees.
