This was just a lawn once.
Don't you think a mouse is eating the sunflower disks? What else could it be? We don't have squirrels.
ADDED @nkristis said, "I had mice eating mine and the damage was similiar".
I was slow to warm to the Heuchera cultivars, but now I can't wait to propagate 'em. Three more would be perfect.
I planted Tithonia diversifolia back there just about 1 year ago from a 4" pot. It's at least 8' tall now.
Here's another strong grower, Solanum Quitoense (Naranjilla). I hope it will fruit for me; I know it's a long shot.
The nursery is jammed, but I recently ramped up my seed sowing work.
