Jason if you have room for a Jasmin then plant one, I have a bee garden and the plants are in an area with the Jasmin at the back of them growing up the fence,it is fast growing and always covered with different types or bees. I have just planted another late flowering one on the other side of the garden, I call them bee bushes.Foxgloves , Lavender,Aquilegias,herbs Borrage and Chives I've found are all very good and any of the garden Geraniums. If you would like some young plants I would be happy to send some to your school.
