Note that the poodle-girls chose the highest point. Of course the rock is dry, but one thing I’ve noticed about Ella, in particular, is that she chooses a position of power if she possibly can.
And then yesterday we planted some shrubs in a granite heap. They are viburnum dentatum, and should be able to handle the dry and slightly shady condition that will come after our current monsoon season is over. Inga and Carol were good sports, barrowing loam up hill and over the ramps to fill the cavities the excavator dug out for the shrubs.
