Pollen Bee Nest

This is a nest for the solitary pollen bees.   I had never seen a nest like this before but thought it looked interesting and decided to order it.    It is now attached to the side of the shed at the back of one of the gardens.    I'm not sure if the bees are using it yet or not - I did see a bee coming out of it once but it's in an out of the way place so you have to make a point of really looking at it.
I've also been busy planting the type of flowers that these bees like so maybe I'll have a full house soon.
