Orchard mason bees are indigenous to North America, and their role as pollinators is crucial to our indigenous plant life. Keeping mason bees is a low cost way to improve our natural environment. They are easy to maintain, and delightful to watch.
While the importance of honeybees to our food supply has been well publicized by the media, the role of native pollinators such as the orchard mason bee and the bumble bee to our ecology is less widely recognized. We are dedicated to increasing the cultural and environmental awareness of orchard mason bees (Osmia lignaria), bumble bees (Bombus), and our many other native bee pollinators.
We have been doing business in Portland, Oregon area for 114 years. We have a large store where you can see all our bee products, and bee educational material. Our online store provides everything you could want to cultivate healthy and productive orchard bees.
Our store hours are: 9:00 am to 6:00 pm, Monday through Friday, and 10:00am to 2:00pm on Saturday.
