Wildflowers of the Sierra Nevada Mountains

I’d heard stories about the glorious wildflower displays in the Sierras, especially this year with all the snow melt, but nothing could prepare me for how many beautiful sights I would discover on the west side of Lake Tahoe last month. As I explored and hiked the forest trails I thought of what it might have been like to be an Native American from the Washoe tribe. How did they use some of these plants and would I find similar species used by our local Ohlone tribes?

I sketched, photographed and identified ( or tried to ) over 49 different wildflowers and admired many more native plants, trees, shrubs. The weather was  perfect for hiking and the sky as blue as the water of the lake.

Lake Tahoe and the land surrounding the lake were once home to the Washoe Indians who wintered in Carson Valley and spent their summers on the shores of the lake hunting, fishing and gathering food for the winter. I’m sure they admired the flower displays as I did.

Red-twig dogwoods bloomed along streambanks. Native Americans used the berries as food, both fresh and dried and cooked. The berries were eaten to treat colds and slow bleeding. The inner bark used as a tobacco either by itself of mixed with manzanita. The bark could also be used as a dye. The wood used for bows and arrows, stakes and other tools.

Pink Sierra currants sported beautiful pink flower clusters and edible blue-black berries. Tribes relished the berries fresh and dried them for later use in the winter. All species in the genus, including our own native canyon gooseberry, have berries high in vitamin C. When dried they were mixed with animal fat and eaten while traveling.

Wood’s roses were in full bloom, their dark pink flowers fragrant in the sun. A variation of the species grows in every western state and throughout Canada. The petals can be eaten raw after the bitter white base is removed. The seed or rose hip contains 24 times as much vitamin C as oranges, vitamin A and E and is also a fairly good source of essential fatty acids, which is unusual for a fruit. A poultice of chewed leaves was used by Native Americans for bee stings. Various parts of the plant were used to treat burns, sores, swelling and wounds and used to make tea-like beverages. All this from a plant that is beautiful, too.

A real looker, the Mariposa Lily caught my eye. Blooming along the trail to McKinney Lake, I thought of how the Washoe would consider these plants a great find, digging up the sweet bulbs to be eaten fresh. We almost missed the Sierra tiger lily mistaking it for the columbines that were nearby. Their orange flowers are much larger but both are stunning to see in the moist meadows.

Other flowers that I encountered were monardella, penstemon, yarrow, lupine, larkspur, arnica, thalictrum, snowberry, giant hyssop, aster, solomon seal, corn lily, mimulus, paintbrush, western burning bush, cow parsnip, wintergreen, phacaela, golden rod, epilobium and sidalcea to name just a few. I was in seventh heaven.

I loved seeing all the rein orchids that were in full bloom. Pine drops emerged from the ground with their urn-shaped downward facing flowers. Plants exist for most of their life as a mass of brittle, but fleshy roots, living in a parasitic relationship with mycorrhizal fungi from which they derive all their carbon. Another unusual plant I saw, pushing up from the ground was the bright scarlet sarcodes or snow flower, a parasitic plant that also derives nutrients from mycorrhizal fungi. Nature has come up with many ways to survive and these are but two good examples.

Native Americans used grasses and pine needles for baskets, willows for household goods, acorns from oaks as a food staple as well as for dyes, medicines, games, toys and construction materials and wild onions for food and flavoring. I’m sure they loved to see the wildflower for their pure beauty as I did.

 

Bonny Doon Ecological Reserve

Recently I went to the moon. At least it seemed like it. Walking through a portion of the 600 acres of burned out  vegetation from the , I couldn’t help but think of it as a moonscape. The misty fog was lifting after a night of rain and milky sun warmed us as we walked through the burned out trees. It was surreal and made even more so by nature’s valiant effort to regrow and fill the void left by the fire. At ground level the earth was bursting with life. Every inch of sandy soil was growing or sprouting something alive. You could almost hear it if you listened closely.

The fire destroyed 3 homes and severely damaged another. About 60% of the Bonny Doon Ecological Reserve burned. It’s amazing to see the recovery already taking place. The bracken ferns came first, followed by the endangered Bonny Doon manzanita some of which have sprouted from their bases while 6" tall starts from seed are everywhere. The burned gnarled trunks rendered the landscape otherworldly and magical. Pockets of manzanitas that were spared by the fire were in full bloom dripping with clusters of delicate, white urn-shaped flowers. This manzanita is endemic to the Santa Cruz sandhills and does not occur anywhere else on the planet. Did you know that manzanita leaves are still used in Russia in the tanning industry due to their high tannic acid content?

Golden chinquapin sprouted from the bottom of their mother tree and around the base are scattered the burr-like spiny bracts that contained a sweet tasting nut. California broom, so unlike the invasive Scotch broom, blanket the ground. They are one of the first plants to colonize an area after a fire and their quick growth can aid in erosion control as well as soil enrichment, through their relationship with the nitrogen producing bacteria, Rhizobium, in their roots.

Large stands of Bush poppies were growing in between the huge manzanita trunks. Bush poppies are common in sandy or rocky soils, often in burned out areas. These plants were taller than I’ve seen elsewhere in this area reaching 4-5 ft  Come spring they are going to be spectacular when they bloom in April-July but they also flower a bit in all seasons.

Silver-leafed lupine were doing their part to help the soil both by stabilizing with their deep roots and building up the nitrogen supply with the bacteria in its root nodules. Warty-Leaved ceanothus grew in large patches and were getting ready to bloom with their deep purple flowers.

Yerba santa were plentiful being an opportunist in the area and finding lots of open areas. They easily sprout from  from the roots after the fire as well as seeding themselves.

This area is a fire ecology and will come back just fine. It’s an extraordinary maritime chaparral habitat with a dense concentration of unique endemics that have emerged here in response to tens of thousands of years of periodic fires.

 

How to Sow Wildflower Seeds

Gardeners who sow wildflower seeds in the fall may envision a springtime scene of brightly colored blossoms billowing in the breeze with butterflies and bees dancing from bloom to bloom. but sometimes when spring arrives, weeds-not wildflowers steal the show.

The most common mistake when planting wildflower seeds is not getting rid of the existing weed and grass seed that is in the soil and germinate along with the wildflowers. These fast-growing weeds smother the slower growing wildflowers. For a more successful planting, take time to eliminate the competition.

First, choose a site in full sun, To get rid of existing weeds, cultivate the soil 3-4" deep and remove all the weeds. This the the method with the least environmental impact.

The next step is crucial. Soak the soil thoroughly, then wait for the weed seeds to germinate. When they do, lightly cultivate the soil to a depth of not more than 1 inch. Deeper cultivation exposes more weed seeds that will germinate along with the wildflower seeds.

Before sowing the seeds, rake the soil to form shallow grooves. Ensure even distribution of seed by mixing with 4 times its volume of sand and broadcast by hand. Rake the seed lightly into the soil and tamp it for good soil contact. Wait for fall rains to germinate the seeds. You can water to keep the soil moist if rains don’t come.

Next year, when the plants have dried and dropped their seed, .  Be sure to take pictures of your meadow in the spring with the butterflies, bees and birds enjoying it.
