Purple Chinese Houses (Collinsia heterophylla) is a low annual (12 to 18 inches high) that flowers March through June. The flowers are gentle tones of lilac, lavender, purple or blue, usually with a white upper lip and arranged in towers of flower clusters that are thought to resemble a pagoda. They are impressive when massed and fit well with ferns and other wildflowers in chaparral, Coastal Sage Scrub, or Oak Woodland landscaping.
Seed can be sown in fall in an area cleared of weeds. The plant will typically reseed itself each year. It is adaptable to different types of soil but needs a moist place in part shade, part sun. In gardens it needs water weekly.
Hosting caterpillars of butterflies and moths, Purple Chinese Houses will also attract bees and benefit birds.
