The principal veins are often depressed on the upper surface. The upper flares vertically, forming a banner at the top of the flower; the lower lip consists of two lobes forming a horizontal shelf that covers the fifth lobe; this, in turn, is folded longitudinally into a “boat keel” which encloses four stamens and one pistil. Photo credit: Barbara Wallach | February 2010, Chinese houses are pollinated by a variety of wild bees which bring pollen from neighboring plants and promote cross-fertilization. Chinese houses are recommended as a plant to attract native pollinators.83 Although few annual plants serve as host plants for butterflies, Chinese houses may serve as a host for the spring azure7 and checkerspot butterflies (W. Butterflies). Most flowering plants have mechanisms to discourage self-pollination. In the Reserve, a colorful display of Chinese houses is found in the spring along the south side of the Central Basin, just west of the eastern end of the Gemma Parks loop trail, at the Sea Dahlia observation site (shown below). Like the other species in the genus Collinsia, which also includes the Blue-eyed Marys, it gets its name from its towers of flower clusters, of decreasing diameter, which give the plants in full flower a certain resemblance to a pagoda. Leaves are bright green, 3/8 – 3 inches (1 – 8 cm). Sign up for email updates, including trail openings/closures, new event announcements, and more. The lower petals are deep purple. They prefer shady, moist areas within many plant communities. Collinsia heterophylla Buist ex Graham – purple Chinese houses Subordinate Taxa The Plants Database includes the following 2 subspecies of Collinsia heterophylla . Encinitas, CA 92023
Collinsia is a genus of about 20 species of annual flowering plants, consisting of the blue eyed Marys and the Chinese houses. Collinsia heterophylla Buist ex Graham. Chinese houses are upright, herbaceous annual plants about one foot high with one or a few upright stems. The underside of the leaves lack hairs or have only a few hairs on the midveins. Seeds develop in a dry capsule which opens at the top allowing about 20 seeds to shake out. Collinsia heterophylla, known as purple Chinese houses or innocence, is a flowering plant native to California and the Peninsular Ranges in northern Baja California.
The Plantaginaceae contains nearly 100 genera. In Collinsia heterophylla, the style lengthens and matures at the same time as the fourth stamen placing them in close proximity when mature and promoting self-pollination. Stamens and pistil enclosed in folded lower lobe | Rios trailhead | April 2014, We know of no uses by Native Americans or early settlers. Their common name comes from the spikes of flowers which are arranged in perfect whirls of ever-decreasing diameter, resembling fairy tale Chinese pagodas. The genus Collinsia has become a guinea pig (more correctly, guinea plant) for the study of this strategy. It was traditionally placed in the snapdragon family Scrophulariaceae, but following recent research in molecular genetics, it has now been placed in a much enlarged family Plantaginaceae. Under close study, however, this simple scenario quickly becomes more complicated. Rating Content; Neutral: On Aug 5, 2001, mystic from Ewing, KY (Zone 6a) wrote: Easily grown and graceful, Collinsia bicolor is popular for its long flowering season. P.O. Many available references still present the earlier classification system. These situations might occur at the edge of the population range or in highly variable environments, and then it may be an advantage to the population to forego maintenance of population variability in exchange for population survival. The leaf shape is variable, ranging from oblong at the plant base to long-triangular along stem,and decreasing in size upward. Our plants are variety heterophylla, which is the more common and widespread variety.
