Plant of the day: goldenback fern

Now that the rains are here, goldenback ferns (Pentagramma triangularis) are starting to emerge. Their lacy green triangle-shaped leaves are emerging from rocky cliffs and stream banks. The leaves alone are quite distinctive-looking, but if you aren’t sure what you’re looking at just flip one over. The entire underside of the surface is covered with tiny spores like a layer of fairy dust. Usually this turns the leaf bottom a startling pale-golden color, but sometimes it can appear more white or mature into a duller brown.

If you want a little forest decoration while out hiking, you can pluck a leaf and carefully place the spore-side down against your clothing (or skin) and give it a quick smack. Often you’ll have a perfect, pale-gold fern print left behind.

Plant of the day: winter speedwell

Veronica_persica2Patches of small blue flowers are blooming between the rows of winter beets and chard on a friend’s farm. This is winter speedwell, or Veronica persica. The local speedwells are easy to identify: look for little flowers with four petals, one noticeably smaller than the others. The other distinctive feature is a protruding pair of antenna-like stamens.

Winter speedwell has flowers that rise from the stem on long stalks (aka pedicels), so they stick out beyond the roundish, scallop-edged leaves. Some speedwells are native, but this one is not–though neither is it particularly invasive. Veronica_persica1

“Plant” of the day: orange jelly

Dacrymyces_palmatus1Which witch is which? As mentioned on Halloween, the slimy and wonderful witch’s jellies can be hard to tell apart. Orange jelly Dacrymyces palmatus (also called orange witch’s butter or witch’s jelly) is the only one that lives on the dead wood of conifers. It often looks very much like a brilliantly colored, tiny brain–but it can become more flattened as well, so the best way to ID it is to know what kind of tree it is growing on. In this photo you can see the tiny blisters of sap under the bark that let you know you’re looking at a young Douglas fir tree.

“Plant” of the day: sudden oak death

The killer that is laying waste to the oak trees of California is almost invisible. Sudden oak death got its name before anyone knew why the trees were dying; eventually the cause turned out to be Phytophthera ramorum. The only outward sign of infection is a dark, bleeding ooze that leaks down the bark. But a second fungus, hypoxylon, is almost always associated with the disease–this one fruits into a distinctive black growth that emerges from the bark and looks like a mound of dark, hardened foam. But inside the tree the infection is running rampant.

While tanoaks and several species of oaks are the most likely to die from the disease, several other species are carriers–including redwoods, rhododendrons, and pepperwood. The spores of Phytophthera can’t travel far; they rely on the splash and flow of rainwater to carry them. But hikers, bikers, and ATVs do a much more effective job of moving the infection from place to place. It can also spread on firewood and the equipment used to do tree work. The sad truth is that even if it moves slowly, certain trees–like tanoaks–have no resistance to this disease. Once it reaches them, they will die, and someday they are almost certainly going to be locally (if not totally) extinct.

Plant of the day: tan oak

Notholithocarpus_densiflorus1

Notholithocarpus densiflorus

The beautiful tree is dying.

From Big Sur to Brookings, entire groves have browned and fallen. Single snags stand in forests like wisps of smoke, like ghosts.

Sudden Oak Death is old news these days – but how does news of a plague become old? The beautiful tree is dying, and eventually it will be gone. With it, a piece of California will be gone as well.

There is a reason the Kashaya-Pomo tribe called the tan oak Chishkale, or “beautiful tree”. Its bountiful harvest of acorns was one of the best foods around. The Kashaya and other native people soaked and beat the nuts into breads and cakes, gruel and soup. During a flu, they sucked acorns like cough drops. For celebration, strung acorns were twirled in the air to make music.

Notholithocarpus_densiflorus2Chishkale has been a generous neighbor to humans and non-humans alike. Northern flying squirrels, dusky footed woodrats and black salamanders are just a few of the myriad creatures that call its roots and limbs home. Their nutrient-packed nuts are a key fuel driving the engine of the ecosystem here in the coastal hills where it lives; deer, squirrels, woodpeckers and jays all dine on the bitter fruit. They were a favorite snack for grizzlies, before the bears were driven from the state. And when feral pigs arrived, acorns became a rooting prize for the hogs as well.

Other creatures eat the creatures that eat the acorns, and when fruit and flesh decay, still more creatures dine on that. Their offal enriches the soil, from which more plants rise. Without them, the engine will falter – and then, because nature eternally adapts, it will change. But something precious will be gone for good.

So, if you aren’t from around here, go outside now. Go and spend time with the tanoaks while groves still live. While they still stand in crowds or pairs and or singly among other trees on a hillside.

Ideally, do this in late summer, when the acorns have fallen and you can see how thick they are on the ground. Find somewhere that the trees grow closely. In places the acorns crunch under your feet like gravel. Notice how dark green the leaves are: serrated like a bread knife, with undersides coated with a soft beige fuzz.

Leave the trail; you are on a brown carpet of leaf and twig. The air smells uniquely dusty and a little soft, thick with the down from the leaves. Sunlight filters down in shifting patches, and squirrels and jays chatter and call. Sometimes a raven swoops through with a heavy push of wings, a dignified awk awk. With a breeze, you may notice that the sound these particular branches make in the wind is like all branches in all wind, and also like no other branches on the planet.

If it is a warm day maybe you will want to find a nice tree, an old one with a broad trunk, and take a nap at its base. When you wake up, you may think of how long your companion has been in this spot, of what it has stood witness to. And mourn for a minute that soon it – and all of its kin – will be gone.Notholithocarpus_densiflorus3

Plant of the day: five finger fern

Adiantum_aleuticum1A lacy fern parasol hangs from the side of an earthen cliff. Each slim stem is topped with a spreading fan of fronds. This is five finger fern (Adiantum aleuticum), found most often in canyons and moist, shaded hillsides.

It’s in the same genus as the striking maidenhair fern, and one of its traditional uses is as a wash to make hair more shiny. Five finger fern tea was also used by Native Americans as a general tonic to treat congestion, sore throats, and other ailments. Chewed leaves were applied to wounds to stop bleeding. One source says it was highly valued as a medicine up through the 1800s.

It is said to grow readily in moist and shaded gardens, and is generally resistant to deer.

Plant of the day: threecorner leek

Allium_triquetrum2Is this little bloom early or late? We’re at the time of the year when it can be hard to tell. Threecorner leek (Allium triquetrum, also known as white flowered onion) is a pretty little weed that can cover entire meadows in the spring. The nodding white blossoms have six pointed petals, each decorated with a single green vein, and usually grow in clusters at the end of a leafless stalk.  The fleshy stem is triangular in cross-section, giving rise to its name. The rest of its name comes from its mild garlicky flavor and smell.

The flowers, leaves and bulb of the threecorner leek are all edible–you can add the leaves and flowers to a salad or eat them along the trail. Older leaves and the small bulbs are best cooked.

Allium_triquetrum1

Threecorner leek is native to Europe and Africa.
