Monarchs are beginning to chain up. There aren't very many of them, but they're hanging in groups on the trees. I saw a dozen or so on Home Base.
EDIT 10/5/18: I went back out and planted 10 Lavender muscari 'Grape Ice' around the forest garden. These have white bells on top that open into red-violet flowers below.
I heard a bluejay screaming "Thief! Thief!" in the yard but couldn't spot him. I did notice that there are few apples left on the Criterion tree, but the pears are ripening.
