Two Showy Mountain Buckwheats
By Jim Moore
One of the pleasures of hiking up to the top of our local ridges and mountaintops; besides the grand view at the top, is all the captivating views along theway up. For me, keeping my eyes to the ground along the way up, is the meansof seeing and discovering many marvels of nature: lichen and mosses, ferns and grasses, stones and large rock formations, perennial and annualwildflowers, and of course squirrels, birds, lizards, butterflies, bees, and bugs of all sorts. I am always stopping to ponder these wonders, and preserve the memory of them on my camera.
Shared now, from one such adventure up to a local mountain top, Goodrich Mountain, are two beautiful species of wild buckwheat, photographed back in 2009: the Many-flowered Buckwheat (species Eriogonum umbellatum var.polyanthum), and Bear Buckwheat (species Eriogonum ursinum).
The Many-flowered Buckwheat, with the red flower centers, was the first beauty that I encountered on my hike to the top. It is so named because it’s mats of foliage often displays many more flower heads than the primary variety: the Sulphur Flowered Buckwheat. During the upwards trek it was seen, and photographed, in several loose stony-soil open locations between the mostly forested slopes. The foliage grows fairly flat near the ground; with flowers borne up on short stems. The Many-flowered Buckwheat is native to California, and may also have all yellow flowers only.
The Bear Buckwheat was found only at the top of the mountain, growing here and there amongst large, mostly barren, rock outcroppings. As such they were quite photogenic as they displayed their flat fuzzy foliage, and creamy-colored flowers raised up on long bare stems against the dark bouldery background.
This species is also called the Talus Buckwheat since it grows well amongst the rocky ‘talus’ often found at the base of cliffs and ledges. This species is native and primarily endemic (limited) to Northeastern California. Both species are perennial sub-shrubs that are found in higher elevation
mountain and valley locations. Both are drought, heat, and cold tolerant. In NorCal there are about 30 other local Eriogonum buckwheat species; and collectively their flowers, leaves, and seeds provide food for small birds, bees, butterflies, moths, and many other bugs and small vertebrate animals. Some species of butterflies and moths are solely dependent on a single Eriogonum buckwheat species; co-extinction would occur if the host plant were to first go extinct. There are about 250 other wild Eriogonum buckwheat species, all of which are native only to North America.
