Monumental Questions - Monumental Vegetable?

Yes, indeed! Although I do not advocate for eating things you find in nature, there is one plant in particular that is both lovely to look at and to nosh on.

 

As you may have heard, we here at Tuleyome are beginning to schedule wildflower tours of our very own “deep home place”, the Berryessa Snow Mountain National Monument (Monument). One of the plants that is a reliable observation, easily identifiable and flowering right now as we speak is miner’s lettuce!

 

I must first say please do not harvest miner’s lettuce from the Monument as it is not only delightful for us to look at, it is an important food source for caterpillars and butterflies.

 

Miner’s lettuce (Claytonia perfoliata) belongs to the Purslane family - Montiaceae. Claytonia is one of 17 genera and 230 known species that range from small, herbaceous plants to woody shrubs. Many of the genera of Montiaceae are edible and that does include miner’s lettuce.

 

Miner’s lettuce is native to western North America from Mexico to as far north as British Columbia. Apparently European explorers liked it so much that they carried it back to Europe with them in the 18th century and cultivated it at the Kew Botanical Gardens in London, It has since naturalized throughout the natural landscape.

 

Utilized by Native Americans for generations, miner’s lettuce is a valuable source of vitamins and minerals. During the gold rush, settlers ate it to prevent scurvy, hence the clever common name. According to a study published in the Journal of the American Dietetic Association, a mere 100 grams of miner’s lettuce, about the size of a dinner plate, contains about 35% of your recommended daily amount of vitamin C, 22% of vitamin A and about ten percent of the iron required daily. It also contains protein and the entire plant, with the exception of the roots, is edible, even the itty bitty flowers. Young stems are tender and sweet while the succulent leaves have a bright, fresh taste and seem to melt in your mouth. Strangely enough, we found out last weekend that domestic goats do not care for it; apparently chewing on the rope holding the fence panels together was more tantalizing. It’s also been noted that deer tend to ignore it as well. Entire pages have been dedicated to the plant lauding it for its yumminess in salads, sandwiches and even sushi. Although it is delicious raw, personal experience speaking here, with a very light salad dressing or even just a splash of lemon juice; it can also be cooked as used as you would spinach. However, like spinach, the plant can contain toxic amounts of sodium oxalate which may potentially promote kidney stones among other terrible things.

 

Miner’s lettuce is common in the spring and can usually be found in a moist, shady environment. After a good rain it may pop up in sunny areas but the best stands are usually in well-shaded, cool areas. As the temperatures rise, the plants in the sunny areas begin to dry up and turn blush pink to a deep red. Plants in dryer locations have a bitter taste. It is easy to identify with its basal rosette, many long petioles and leaves that wrap completely around the stem looking like saucers or little lily pads. In young plants these leaves will be bright green and heart-shaped but as the plants mature, they become more rounded or cup-shaped. Mature plants may also have tiny, dainty white to light pink flowers dangling from the center of the saucer-shaped leaf. The plant usually flowers from February to May or even June if conditions are right.

 

While I most definitely do not promote harvesting plants in native or natural ecosystems, miner’s lettuce can easily be cultivated in your own backyard! The best flavor comes from a cool, shady, damp location so plan for an early crop. But, it can also tolerate full sun if the soil remains good and moist. Miner’s lettuce also seems to favor occasional minor ground disturbance and growing it as a seasonal ground cover can be pleasing to the eye and the tummy! Miner’s lettuce can be planted in late summer to early fall in mild climates and harvested all winter. It can also be sown in the spring and with apple water be harvested until the summer heat arrives. The plants can be cut and allowed to regrow several times a season as long as they are eventually allowed to finally flower and set seed as they are an annual species and reproduce by seed. Miner’s lettuce can be used in any recipe that calls for fresh, steamed or cooked greens. Eat your vegetables!

 

Next time you’re hiking in our favorite Monument (you know which one!) keep an eye out for miner’s lettuce and give it a nod. You might find it in several of the habitat types there including chaparral, oak woodlands, riparian and maybe even a parking lot!

From September to June, I worked as a Horticultural Intern at Tuleyome. Each week at the Woodland Regional Park Preserve, I would meet with my mentor Teri Barry. Over the course of the year, we worked together identifying, documenting, and analyzing the preserve's growth. Through this opportunity, I gained experience in hands-on restoration efforts, familiarity with plant taxonomy and classification, and community outreach.

I’m sure you already know that the Bald Eagle is used as a symbol of our Nation’s freedom, strength, perseverance and independence. It is said that our founding fathers chose the Bald Eagle to adorn our Great Seal because it is indigenous to North America and if you look closely at it, you’ll see that it is holding 13 arrows and an olive branch simultaneously symbolizing the power of war and the power of peace. But, what about our national mammal? Er, maybe you didn’t even realize that we had a national mammal… President Barack Obama designated the American Bison as our national mammal in May of 2016. It too is endemic to North America and in prehistoric times, millions of them roamed through roughly two-thirds of the United States. Their range was known as the “great bison belt” - a stretch of habitat that encompassed the forests of Alaska, the grasslands of the North American plains and stretched from the Great Basin east to the eastern Appalachian Mountains. Side note - I’m just gonna come clean right now and tell you that the historic range of the American bison, American Buffalo or just plain bison or buffalo does NOT include the Berryessa Snow Mountain National Monument (Monument). I’m supposed to be writing about the Monument region and I picked a topic that is clearly not there but it’s important and they are impressive so please don’t tattle. Another side note - the American Bison and the American Buffalo are one in the same and both names can be used interchangeably. Its scientific name (genus and species) is actually Bison bison so I guess calling them bison is probably more scientifically accurate but either works. Bison are North America’s largest land animal; an adult male averages about 2,000 pounds - that’s a ton (thanks Schoolhouse Rock, I will never forget this one!), are about 12 feet long from nose to rump and about six feet tall. Females max out at around 1,000 pounds and are a little over nine feet long. In the wild bison can live ten to twenty years. Both females and males have massive forequarters and sport what looks like a shaggy, long-sleeved sweater. Both sexes have short, curved horns that are an integral part of their status in the herd and defensive strategy. During the snowy winters, bison display a dark brown winter coat and in the summer they show off their lighter brown summer-bods. Calves typically arrive from March through May depending on weather conditions. When they’re first born calves are an orangey-red color which earned them the nickname “red dogs”. Within a few months they become darker brown like their parents and their little horns start to poke through. Around this time they also begin to develop their iconic shoulder hump. The hump is made of solid muscle buttressed by elongated vertebrae. This dense network of muscles act as a powerhouse that allows the animal to swing its massive head from side to side and plow through icy snow to access buried forage enabling them to survive even the harshest winters. Although they are not known for keen eyesight, bison have superb senses of hearing and smell. As monumental (get it?) as these animals are, they are shockingly quick and agile. Bison have been clocked at running 35 miles per hour (!), they can spin and turn on a dime, leap over high fences and are incredibly adept swimmers. All these mad skills on a strictly vegetarian diet - that’s ruminant efficiency. For thousands of years, before the European settlers arrived, Native Americans of all tribes and regions revered the bison. They were the cultural, spiritual and resource backbone of indigenous societies across the United States. Every part of the animal was used; the meat was consumed, the hide was used for clothing, shoes and shelters, and the bones and hooves were used for tools and weapons. Even the sinew was used for sewing and bow strings. Everything was copacetic then came the Europeans with their domestic cattle diseases and thoughtless greed. Bison were hunted to near extinction within roughly just 100 years. Their numbers went from an estimated 60 million (!) to less than 550 individual animals by 1889. They were hunted mercilessly and their habitat destroyed, some say as a way to control the Native Americans by removing their primary resource. One of the buffalo’s biggest fans was President Teddy Roosevelt. In the early 1880’s he traveled to what is now North Dakota (shout out to my people!) to hunt. After recognizing the bison’s diminishing population numbers he co-founded the American Bison Society in 1905 to help conserve and protect this American emblem. For many years the few buffalo that remained were only found in national parks and preserves but primarily on Native American reservations. Had it not been for the willingness of tribes across the country to work with interested individuals and state and federal governments, the American Bison would be gone today. Much like the Bald Eagle, the bison is an authentic symbol of American character and as it turns out, another one of the greatest conservation success stories in U.S. history. The bison within the Yellowstone National Park boundaries are direct descendants of the original animals that roamed our country’s grasslands and are the only herd that still occupy their original prehistoric location. This free-ranging herd numbers approximately 5,500 animals and is the largest herd on public land. Recovery efforts paid off and today bison can be found in all 50 states including private and tribal lands, national parks and wildlife refuges.
