Collinsia heterophylla (syn. C. bicolor) is a flowering plant native to California and Baja California. It is known as Purple Chinese Houses or Innocence. Like the other species in the genus Collinsia, which also includes the Blue-eyed Marys, it gets its name from its towers of inflorescences, of decreasing diameter, which give the plants in full flower a certain resemblance to a pagoda.
