Day Lily. Unless it's growing in a ditch. Then it's Ditch Lily.
Arugula Blossoms. This is why those spicy leaves store nutrients. Then they quadruple in size, an explosion of splindley stems & blooms, and go to seed.
Red Potato blossoms. Dainty flowers for an earthy tuber. This year skunks kept the potato beetle population under control, nose funneling the grubs out of the ground.
