Mexicali Onion

Allium peninsulare

Allium peninsulare is a North American species of wild onion. It is known by such common names as Mexicali onion and Peninsula onion; the former referring to the Mexican city just south of the US/Mexican border, the latter referring to the Peninsula of Baja California. It is widespread in California, USA, where it grows in the California Coast Ranges, Sierra Nevada foothills, some of the Channel Islands, and Peninsular Ranges. The range extends south into the northernmost part of Baja California and north into southern Oregon. Allium peninsulare is usually found in Valley Grassland, Foothill Woodland, and Coastal Chaparral at elevations up to 1100 m (3660 feet). The plant produces a bulb 8-15 mm wide and has two to three channeled to more or less cylindrical leaves. Between May and July, it sends up a 12-45 cm scape topped with an umbel of 5-35 flowers, each on an 0. 8-4 cm pedicel. The flowers are red-purple and have six triangular tepals. The three inner tepals are smaller than the outer ones and have teeth along the margins.

Bitter Dogbane

Apocynum androsaemifolium

Apocynum androsaemifolium (Fly-trap dogbane, Spreading dogbane) is a flowering plant in the Gentianales order. The plant is common in North America, and is widespread across most of the United States and Canada, and in Alaska, California, and Northeast Mexico. Apocynum androsaemifolium has branching stems, hairs on the underside of the leaves, and no hair on the stems. Milky sap appears on broken stems. Leaf margin is entire and leaf venation is alternate. Its leaves appear as pointed ovals, while its flowers appear terminally on a stalk. The plant is poisonous, due to the cardiac glycosides it contains.

Pacific Madrone

Arbutus menziesii

The Pacific Madrone (Arbutus menziesii) is also known as the Madroo, Madroa, Bearberry, or Strawberry Tree, or simply referred to as Arbutus. It is a broadleaf evergreen tree with rich orange-red bark that peels away on the mature wood, leaving a greenish, silvery appearance that has a satin sheen and smoothness. The exposed wood sometimes feels cool to the touch. In spring, it bears sprays of small bell-like flowers, and in autumn, red berries.

Plant in a shady or partially shaded location, and avoid direct summer water. It prefers north-facing slopes especially in drier locations. Madrone is a particularly beautiful plant, but it grows very slowly in the southern, drier part of its range, where it typically grows to only 25 feet. In the northern, moister part of its range, it can grow quickly to 100 feet.

It is found on the west coast of North America, from British Columbia to California - but also scattered on the west slope of the Sierra Nevada mountains. It becomes rare south of Santa Barbara County, with isolated stands south to Palomar Mountain, San Diego County and northern Baja California, Mexico.

It is common to see madrones of about 10-25 meters in height, but, in the right conditions, the trees reach up to 30 meter. In best conditions, a madrone can also reach a thickness of 5-8 feet at its trunk, much like an oak tree.

The leaves are thick, oval, 7-15 centimeter long and 4-8 centimeter broad, and arranged spirally; they are glossy dark green above and a lighter, more grayish green beneath, with an entire margin. The leaves brown during the fall season and detach from the branches.

Pacific madrone seeds are dispersed largely by birds but also by mule deer, rodents, and gravity; robins, starlings, band-tailed pigeons feast on the ripe berries and subsequently disperse the seeds as they move about.
