General: Glabrous annual, the several stems spreading to erect, simple or branched from the base, 10-30 cm. high. Leaves: Leaves alternate, fleshy, entire, linear to oblanceolate, 1.5-7 cm. long and 2-10 mm. wide, narrowed to slender petioles, with a few marginal hairs. Flowers: Flowers single in the leaf axils below, becoming racemose toward the branch ends; pedicels stout, 3-10 mm. long; sepals 2, unequal, 3-8 mm. long, ovate, one usually pointed, with coarse, marginal hairs; petals 5, equaling the sepals, deep crimson or rarely white; stamens 5-12, the filaments broad, free to the base; style short, stigmas 3. Fruit: Capsule papery, 3-valved, equal in length to the sepals.

Small, brilliant, bright reddish-pink, shallowly bowl-shaped flowers bloom on short stalks growing from axils of upper leaves on this succulent plant with spreading or erect stems. This species is a member of a large genus of the western Americas and Australia named for a Swiss botanist of the 18th century, J.L. Calandrini.

Bloom Period


Southern British Columbia, west of the Cascades in Washington (where uncommon), both sides of the Cascades in Oregon, and California.


Ecological Setting-Gravelly to heavy soil, usually where vernally moist, at low elevations. Soil Texture-Poor, dry, sandy to loamy soil Nutrients-Low to moderate nutrient availability Moisture Regime-Moderately dry to moist conditions Shade Tolerance-Full sun Successional Status-Early


Site Rehabilitation-Calandrinia ciliata is an early colonizer of disturbed areas. It increases in abundance following a fire because of the increase in nutrients and the decrease in competing grasses

Wildlife-Many insects, small mammals, and birds, including wild doves (Zenaida spp), eat the seeds. Cattle readily graze on fringed redmaid plants.

Landscaping-Fringed redmaids look lovely when grouped with other low-growing wildflowers

First Nations-Leaves and young shoots can be eaten raw, cooked or used as a garnish and make a tasty salad. Seeds can be eaten raw or ground into a meal. The seed can also be cooked as a piñole. The seed is very small and fiddly to harvest, especially since it ripens intermittently over a period of several weeks. However, it is rich in oil and was often collected in large quantities by native North American Indian tribes. Seeds and greens were an important food source for many tribes in California including those whose territory neighbored the Salinan. Given their importance and their abundance, they were undoubtedly utilized by the Salinan as well. The shiny black seeds were a major ingredient in pinole (from the Aztec word for seed flour, pinolli) and were valued for their high oil content. The Chumash called the seed xutash or pil ([1]). The name pil is reported in Onlone usage for redmaid seeds (Bocek 1984). Fages (1937) names pil as the seed of a plant used by the Salinan. The Miwok harvested the seeds in early summer ([2]). The plants were pulled and spread out on a clean area to dry. The seeds were separated by shaking or hitting the plants over the cleaned area or into a basket. Then they were placed into a tightly woven winnowing basket where they were tossed, allowing the moving air to remove any chaff. The seeds were then dried for storage or parched in a cooking basket along with hot coals. The contents were kept in motion to prevent the coals from burning the basket. The parched seeds were pulverized in bedrock mortars into an oily meal, which was then prepared into balls and cakes. Large quantities of Calandrinia ciliata seeds have been recovered by archaeologists in burial sites in Chumash territory in the Channel Islands of Southern California. Not only were the seeds used as ceremonial offerings, as evidenced by these burial sites, but also they are often mentioned in Chumash myths. The Luiseño ate the tender young greens fresh, which are said to taste similar to arugula. Fringed redmaid greens contain oxalic acid, like spinach, and should be eaten sparingly. Cooking reduces the amount of oxalic acid.

Other-The plant contains oxalic acid, so it should only be used in moderation. Oxalic acid can lock up certain of the nutrients in food and, if eaten in excess, can lead to nutritional deficiencies. It is, however, perfectly safe in small amounts and its acid taste adds a nice flavor to salads. Cooking the plant will reduce the quantity of oxalic acid. People with a tendencies toward rheumatism, arthritis, gout, kidney stones and hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition.


Plants are intolerant of root disturbance, they are best treated as half-hardy annuals and sown in situ in late spring. In frosty climates this species can become a self-sowing annual, the seed germinating in spring. Mix the seeds with ten parts moist sand to ensure even broadcasting. Broadcast the sand and seed mixture over the prepared bed and scuff or rake the seeds lightly into the soil. Water lightly and keep the soil lightly moist until the seeds sprout (generally within one to three weeks when temperatures average 20°C). The plants are moderately drought tolerant once established. Germination usually takes place within 1 - 3 weeks at 20°c.

Crop Intervals Annual


Caladrina ciliata

Abbreviation: CACI

Seed sample from: 2010

Average Measurement: 1.6 x 1.3 x 0.7

Measurement Range: L: 1.2 - 2, W: 1.1 - 1.5, D: 0.5 - 1


Shape: Lenticular with a narrowly winged margin. About 1/2 the size of Montia linearis. CACI tends to have a slightly heavier lip near hilum when compared to MOLI.

Color: Black

Surface: Seed has bumpy texture and is very shiny.

Could be confused with: Montia linearis

Latitudinal Cross Section: rhombic CACI-rhombic.png

Longitudinal Cross Section: rhombic CACI-LONG-rhom.png

Basic Explanations and Assumptions:

The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.

Measurements included are the mean average for each measurement of ten separate seeds.

All measurements in millimeters unless otherwise noted.
