Monumental Questions - Monumental Vegetable?

Kristie Ehrhardt • March 5, 2026

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!

Welcome Interns!

By Geoff Benn • October 7, 2026
Interns Deana Martinez, Yaquelin Gonzalez, Gabriella Limon, Ben Hubbard, and Keira Lazaro at Woodland Regional Park Preserve. Tuleyome is excited to welcome our largest ever cohort of interns, including four Horticultural Interns and one Communications Intern! Our Horticultural Interns are paired with volunteer mentors at Woodland Regional Park Preserve where they learn about managing invasive plants and monitoring populations of rare native plants. This year’s mentors are Jennifer Hogan and Teri Barry, both longtime volunteers and leadership team members at the Preserve. Our Communications Intern works closely with Program Director Nate Lillge to shape and execute our communications, including social media, e-newsletters, and more. Keep reading to meet each of our interns: Horticultural Intern Yaquelin Gonzalez has lived within the bounds of Sacramento County her whole life, where her mother’s garden and love for rock collecting sparked her appreciation for nature. Her desire to enter the environmental field was further fueled via nature-based field trips during elementary school. After high school, she began studying at American River College and eventually transferred to the University of California, Davis in 2025 to study Environmental Science and Management, focusing on Ecology, Biodiversity, and Conservation. Here, she has gained an interest in soil science as well as plant ecology and hopes to pursue a research career in restoration ecology. In her spare time, she likes to go on nature walks, play the guitar, read, bake, and listen to podcasts. Horticultural Intern Ben Hubbard grew up in Roseville, California where he spent a lot of time outdoors with friends, competing in sports, hiking, as well as instructing elementary school field trips about the environment, specifically wetlands. He just recently transferred from Sierra College to the University of California, Davis and is working towards completing his Bachelor’s degree in Environmental Science and Management with a specialization in Ecology. When he completes his education, he hopes he can make a difference in the world and help to preserve wildlife and natural land for the next generation to enjoy as much as he has. When he’s taking a break from studying you can find him practicing with his recreational sports team, grabbing a coffee, hiking, enjoying a good story, or just hanging out with friends. Horticultural Intern Keira Lazaro is a third year undergraduate at University of California, Davis where she majors in Environmental Toxicology. She’s specializing in pharmacology and biotechnology with hopes to work in a research lab on specific pathogens that attack native California crops. She is also a part of the University Honors Program in Davis and is taking the first couple of steps towards her fourth year signature work on the oxidation chemistry behind electronic cigarette devices, specifically with exposure in indoor environments. Keira grew up in Los Angeles County and hopes to find a career in Southern California once she graduates. When she is able to go back home she spends most of her free time at the beach or hiking. Communications Intern Gabriella Limon grew up in Bishop, California, within the Sierra Nevada and Owens Valley where she became connected with wildlife and stewardship. She spent her later teenage years in Southern California and committed to the University of California, Davis, where she is currently pursuing a Bachelor's Degree in Environmental Policy Analysis and Planning with a focus on conservation management. In addition, she is also a scholar staff member of the UC Davis Women’s Resources and Research Center where she provides STEM-based programming and academic support to students of marginalized identities. Gabby is especially passionate about wildlife justice, land protection, and environmental education. She spends her free time writing, playing video games, tide pooling, hiking, and logging critters. Horticultural Intern Deana Martinez grew up in Arbuckle, California, surrounded by rice fields and almond orchards, which grew her interests in agriculture. She is currently in her 4th year at the University of California, Davis, where she is pursuing a Bachelor’s Degree in Entomology with a Soil Science minor. Along with classes, she is involved in a Nematology research lab, working with plant parasitic nematodes and their interactions with common crop systems in California. She has also held a student position with the Plant Biology research greenhouses as a technician for the past 3 years. Outside of school and work, Deana enjoys hiking, reading, and spending time with her family.

Policy Corner: California Fights Back on Endangered Species Protections

By Shai Demus • October 7, 2026
California’s condors and sea otters are two of conservation’s great comeback stories – species that were once on the brink of extinction and have rebounded thanks in large part to the Endangered Species Act (ESA). That 50-year-old law is now facing one of the most significant rollbacks in its history, and California is fighting back in court. Last week, Attorney General Rob Bonta, joined by a coalition of 21 state attorneys general, filed two lawsuits challenging the Trump administration’s recent changes to the ESA. At the center of the fight is a single but enormously consequential change: the administration rescinded the longstanding definition of “harm” under the Act – a definition that, since the early 1980s, has made it illegal to destroy or damage the places endangered species live, breed, and feed. Without it, habitat destruction itself may no longer count as illegal “harm” to a species, even though most biologists agree habitat loss is the single biggest threat facing endangered species today. The changes don’t stop there. The administration is also making it easier for federal agencies to avoid designating “critical habitat” for at-risk species, and it has eliminated automatic protections for newly-listed threatened species – meaning wildlife officials must now write custom protection rules for each species one at a time. That’s a heavy lift for an agency that has reportedly lost more than a third of its staff, and which currently has 400 species waiting for a protection decision. Why this matters here at home California is home to more threatened and endangered species than any other state. It’s natural to assume the state’s own Endangered Species Act would fill any gap left by federal rollbacks – but legal experts point out that California’s law, as written, doesn’t clearly protect habitat at all. It primarily prohibits killing or injuring individual members of a listed species, not damaging the places they live. That means the very thing under threat federally – habitat protection – may not have a reliable backstop at the state level either. What this means for our work At Tuleyome, so much of what we do, protecting oak woodlands, wildlife corridors, and watershed habitat across our region – depends on the basic principle that a species' home matters as much as the species itself. A condor or a Clear Lake hitch can’t survive court-ordered protection from hunting alone if the habitat it depends on is quietly bulldozed, drilled, or logged out from under it. This lawsuit is about defending that basic principle at the federal level, and it’s a reminder of why local land protection and legislative advocacy matters now more than ever – because the safety net above us may have real holes in it.
