Hi, we have two raised flower beds that sit along the fence at the south end of our garden, which means they are always in shade. We would like to plant some bee friendly plants, but don't want anything that gets too big.
We also have a dog, so need to be mindful of any plants that may be poisonous.
Is there anything that would be suitable?

Yes. colorful shade plants include almost any Begonias, Coleus, ferns, Impatiens walleriana, Persian shield. Bees go nuts for Coleus blooms.
