Collinsia heterophylla

Collinsia heterophylla, known as purple Chinese houses or innocence, is a flowering plant native to California and the Peninsular Ranges in northern Baja California. Collinsia heterophylla is an annual plant growing in shady places, 10–50 centimetres (4–20 in) in height. It can be found in most of California (other than desert regions) below about 1,000 metres (3,300 ft). It blooms from mid spring to early summer. Like 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.
