I took a walk around to see what flowers were growing and being visited by bees. The dandelions were still in bloom in areas and quite popular. The onions I left over winter to go to seed were blooming. The bees really like onions. As yo can see in the photo above some plants had more than one bee at a time.
The huge poppies were very popular with the bees. These were here when we purchased the property in a planted around a worn out cement little pond or pool. I tired to transplant some last year without luck. They are not in a good area in the lawn so we have to mow around them until they stopped blooming. I tried before blooming but this year I will try after blooming to see if I can get some in a back yard planter.
The saliva was very popular last year and now that it is blooming it is very popular with the bees. There are at least three bees on the flowers in this picture. I really like this plant since it is easy to grow and a perennial.
