San Francisco Spineflower

Chorizanthe cuspidata

Chorizanthe cuspidata is a species of flowering plant in the buckwheat family known by the common name San Francisco spineflower. It is endemic to California, where it is known only from the San Francisco Bay Area and to the immediate north and south. It grows in sandy coastal habitat. The Chorizanthe cuspidata plant grows flat along the ground, its stems extending up to about half a meter in length. The leaves are located about the base of the stem and are generally oval in shape and up to 5 centimeters long. The herbage is hairy to woolly in texture and green to reddish in color.

The inflorescence is a dense cluster of cylindrical flowers, each bordered by white or pink bracts with hooked or straight spines at the tips. The flower itself is 2 or 3 millimeters long, white or pink, and hairy. The minute tepals are lobed, with the central lobe longest and coming to a point. VarietiesThere are two varieties of this species:Chorizanthe cuspidata var. cuspidata is quite rare due to its Bay Area habitat having been mostly consumed for development. Chorizanthe cuspidata var. villosa can be found in the protected habitat of Point Reyes National Seashore.

Western Water Hemlock

Cicuta douglasii

Cicuta douglasii (Western water hemlock) is a poisonous plant in the family Apiaceae. It is a perennial plant that grows in wet places such as marshes, stream banks, slough margins, ditches, meadows, and wet pastures. The roots of this plant are thick and tuberous, with many smaller tubers coming from the main tuber. This root structure allows the water hemlock to adapt and survive wet conditions. Water hemlock is most abundant in British Columbia, and is indigenous to North America. In North America it primarily grows from the base of the Rocky Mountains to the Pacific coast, stretching all the way from Alaska down to California. Water necessities limit this plant from growing in open rangelands. The characteristics of water hemlock include its stem which is 0.5-2 meters tall with purplish spots, thick roots, and leaves that are compound pinnate and alternate. The leaflets are usually 5-8 centimeter long and 1-2 centimeter wide with jagged edges. The flowers on it are compound umbellate flower clusters with many small, white flowers. There are two seeds for each flower. Seed dispersal for water hemlock seeds comes from means of wind, water, machinery, on clothing, and through transported soil. The seeds germinate in spring, and flowers mature near the end of June and beginning of July. In addition to sprouting new plants from seeds, rootstocks can also product new plants. These are formed in the fall from the basal meristem, and when they detach the following spring, they may form a new plant.

Beaked Hazelnut

Corylus cornuta

California hazel (Corylus cornuta var. californica) -- also commonly called beaked hazelnut or California hazelnut -- is an evergreen shrub in the Birch family (Betulaceae). Delicate stems are clothed in velvety birch-like leaves which turn golden yellow in autumn. Springtime brings dangling cream-colored catkins before the leaves appear, which can resemble tiny ornaments when viewed from a distance in a forest. Although ruby red, the flowers are quite small, and escape notice unless one is looking for them.

Butterflies and moths are attracted to the flowers and Early Hairstreak butterflies use the plant to lay their eggs. Wild birds feed on the high-protein winter buds and spring catkins. Hazelnuts are famous for their fruit, which is a delicious nut that is enclosed in a papery, beaked-shaped husk. Our native hazelnut, while not as productive as the commercial crop (European Hazelnut, Corylus avellana), may require protection from wildlife if one wishes to grow it for its nuts.

California hazel thrives as an understory shrub or small tree in Woodland habitats, flourishing in part to full shade and slightly moist, well-drained soil near creeks, streams, or under dense tree canopies. Gardeners who are interested in growing their own food using Permaculture or Food Forest methods, can include this plant in the shrub layer. For those who wish to attract wildlife, this is also a wonderful choice. California hazel adds a delicate, ethereal quality to a woodland garden and those with shady yards will find this shrub to be a great addition to their landscapes.
