May 4-5, 2019: Mariposa Butterfly Festival

Mariposa Native Plants was present at the Butterfly Festival in Mariposa. Many of the festival visitors were not aware of the close relationship between the monarch butterfly and the milkweeds in the Asclepias genus. We sold over 30 milkweeds, including A.fascicularis, A.speciosa, and A.eriocarpa, as well as a number of other California native plants.

June 22-23, 2019: Monarchs and Milkweeds public workshop presentation

Ron Allen (IT Manager, Mariposa Native Plants and UC Master Gardener, Mariposa County) and Ted Barnecut (UC Master Gardener, Sutter County) presented a public workshop sponsored by the UC Master Gardeners on Monarchs and Milkweeds on June 22nd at the Board of Supervisors chambers in Mariposa. The next day, we went on a milkweed survey in southern Mariposa and nearby Madera Counties. The photo shows Ron & Ted next to a large patch of Showy Milkweed, A.speciosa, along Tip Top Road in Mariposa.

August 10, 2019: Planting initial milkweed plot at Heather & Dave's ranch in Hornitos

Ron & Bev brought 10 milkweeds (6 A.fascicularis, 2 A.speciosa, and 2 A.eriocarpa) out to Hornitos and helped Heather put them in the ground. Later we found out that the gopher screens we put in the ground with them were inadequate, and several plants were eaten. We now realize that a mesh with holes no larger than 1/2 inch is required.

September 22, 2019: Mariposa Native Plants appears on the Calscape website

MNP is now listed among the native plant nurseries on the Calscape website: Calscape (CNPS).

October 23, 2019: Pacific Blackberry!

OMG! I was hiking over the southern portion of Mariposa Native Plant's cultivation area near Midpines Summit, about 6 miles east of Mariposa, checking on the tree pruning operation that taken place in the last few days. At the bottom of an ephemeral stream course, I stumbled upon a number of Pacific Blackberry (Rubus ursinus) vines! Around Mariposa, one typically finds a lot of Himalayan Blackberry (Rubus armeniacus) infestations, but this invasive plant can be distinguished from our native blackberry by its having more than 3 leaflets and its evergreen growth habit. Native blackberry vines always have exactly 3 leaflets, as in the photo, and they are winter deciduous. We will be trying to cultivate this native blackberry in the coming months. Stay tuned.

November 22, 2019: CalFire's Kuldeep Singh visits Mariposa Native Plants

Kuldeep is the Horticulturist and Nursery Manager at CalFire's L.A. Moran Reforestation Center in Davis, CA. He came to visit MNP at our cultivation location in Mariposa to learn the finer points of propagating Canyon Live Oak (Quercus chrysolepis) from acorns. MNP IT Manager Ron Allen met with Kuldeep, showed where and how we gather Q.chrysolepis acorns, reviewed the stratification process, explained how to gauge the health of an acorn, and showed how they are started in propagation deeppots (photo at right).

December 16, 2019: Mariposa Native Plants buys a label printer

MNP purchased a commercial quality Datamax-O'Neil label printer. We've begun printing out pot labels and using them to organize our inventory. It took a bit of fussing with the printer to get it to work, because, as it turned out I (RLA) had the printer ribbon installed backwards on the machine. OK, well, there were no instructions in the install kit about which type of ribbon I was working with, nor were there any instructions about how to determine the type of ribbon in my hand, the end, by trial and error, we began to crank out the damn pot labels. I thought about having a cute butterfly logo on the label. But, I thought that it was more important to have print type as large as possible--and so to remain legible on the pot stake while subject to weathering-- and yet contain the very basic, minimal information that a buyer would need in order to locate and grow the plant. So, that's why our plant stakes are a bit more stark and glib than others you might encounter.

December 26, 2019: Holiday gift of acorns

From Greg and Michalene in Bootjack, MNP received the holiday gift of a batch of acorns from the Oracle Oak on their property. The Oracle Oak is a natural hybrid of Black Oak, Quercus kelloggii, and Interior Live Oak, Quercus wislizeni. The odd thing about this tree is that it's physical characteristics seem to lie almost perfectly in the middle of the tree characteristics of its parent plants. It is semi-deciduous, dropping only some of its leaves in the winter. (The Black Oak is deciduous, but the Interior Live Oak is wintergreen.) It has a leaf that is not as wide and not as deeply-lobed as the Black Oak, but still has the spines and the narrow, elongated aspect of the Interior Live Oak leaves. The acorn is not as barrel-shaped as the Black Oak's, but they are not long and thin like the Interior Live's. It's really an attractive oak tree. We will attempt to propagate this specimen from acorns. The acorns are currently in stratification. As a side note, there is an Oracle Oak on MNP's property in Bootjack as well, but it did not produce substantial acorns this year.

January 11, 2020: Hite's Cove trail hike and plant collection

Mariposa Native Plants and UC Master Gardener Ron Allen were invited to pull plants from the Hite's Cove Trail above the South Fork of the Merced River on January 11, 2020. I (RLA) accompanied Bill King and his trail crew, only removing plants that intruded onto the established trail. Bill works with a volunteer crew of trail maintainers under the auspices of the US Forest Service (USFS). After the Briceburg Fire, the trail is closed to the public, but Bill and his crew have permission from the USFS and local land owners to enter onto the trail and perform maintenance work. I was able to collect about two dozen small Ceanothus tomentosus (Woollyleaf Ceanothus) plants that had grown into the trail. Here are my bags and backpack about to head back to Highway 140 (right). I had anticipated that I might fill the shopping bag there as well, but since the trail turned out to be quite precipitous, I decided that a free right hand was the way to return to my truck. Overall, it was a great morning. Within Bill's crew were Marty, Dave, Connie, Jack, and Ralph, as well as myself. Ralph Mendershausen gave a great talk to our group, right at the place where I gathered plants. He covered the history of Hite's Cove, from the time that the Native Americans fished the Merced River for salmon and crushed acorns into meal in the rocks right behind us, to when Hite developed a productive gold mine further up river, and then to when Chinese workers built a sluice works and brought in a stamping mill over from Jerseydale to crush quartz and extract gold ore in the 19th century.

June 17, 2020: Mariposa Farmer's Market

Mariposa Native Plants set up a booth and tables at the Mariposa Farmer's Market, 6th and Jessie Streets in Mariposa, California. We sold out of the Narrowleaf Milkweed that we brought for sale. We sold a variety of far more attractive native plants, such as the Bush Anemone (Carpenteria californica), or just Carpenteria, shown here. Carpenteria is a widely available nursery plant, having been propagated from its origins just east of Fresno in the Sierra foothills. It is an evergree shrub, and it is well-adapted to the Sierra foothills.

August 3, 2020: Mystery seeds in the mail

A number of people across the United States have been receiving some complimentary seed packages from China. DO NOT OPEN THE PLACKAGE, AND DO NOT PLANT THEM. As far as has been determined, the seeds are not harmful, but one should not plant seeds that come from an unknown source. If you receive them, you should not open the package, and you should send the packet to your local Agricultural Inspector's office.

April 11, 2021: Asclepias erosa seedlings

MNP customer Ryan G in Wrightwood, CA, sent this photo of his Asclepias erosa seedlings. Commonly known as Desert Milkweed, A.erosa grows in the Mojave Desert region of Southern California, into Arizona, and south into Baja California. Once they are nice and tall, the plan is to plant them out in the desert in order to provide further habitat for the Monarch Butterfly caterpillars. We don't carry this plant at MNP. It does grow in the area around Bakersfield, however, and even as far north as Visalia, CA. I wonder if it's worth investigating for planting in the Sierra foothills.

July 3-4, 2021: Mariposa Butterfly Festival

MNP had a booth in the Habitat Row at the Butterfly Festival this last 4th of July weekend. The festival was very well attended. In fact, although it wasn't supposed to open until noon on the 3rd, people swarmed into the fairgrounds starting around 10am. We were setting up the booth and unloading plants while people were asking questions and trying to buy a plant. Overall, we talked to a lot of people about native plant landscaping and sold over 40 plants.

August 1, 2021: Asclepias vestita seeds

Our collection of roadside Woolly Milkweed seeds in Mariposa and Madera Counties was less than spectacular this year. We have a limited supply of seeds for Asclepias vestita, and we will be limiting the volumes of seeds that we sell to individual customers. It's also unfortunate that the recent River Fire in southern Mariposa and eastern Madera Counties destroyed a lot of the Woolly Milkweed habitat. We were able to verify that many of our most reliable seed source plants were outside the main burn area, although some had been run over by fire equipment.

August 25, 2021: Coyote Mint (Monardella villosa) seeds

We have collected a bit more Coyote Mint seeds this summer. The seeds do not need any special treatment; you can just plant them directly into germination containers. We recommend that you sprinkle a few of the seed husks into an individual container. If multiple sprouts arise, then cultivate them for a few weeks and clip off the weaker ones to ensure a single Monardella villosa in a single germination cup. Keep the planted seeds moist, and when they begin to sprout, move them gradually into brighter sunlight.

August 26, 2021: Interviewed!

MNP owners Bev & Ron were interviewed by our local newspaper, the Mariposa Gazette.

September 28, 2021: Meeting with Sunburst Nurseries

MNP IT Manager Ron Allen met with Jim Reed and Rick Lafferty of Sunburst Nurseries of Porterville, CA. Rick and Jim were investigating the cultivation of native California milkweeds.

October 5, 2021: Conversation with California Department of Fish and Game

MNP IT Manager Ron Allen discussed milkweeds and monarchs with Diana Magor of the California Department of Fish and Wildlife. Diana was interested in our cultivation techniques at Mariposa Native Plants, how well the various Asclepias genus milkweeds provide predator prevention through the uptake of cardiac glycocide toxins into the monarch butterfly caterpillars, and, finally, and how well the plants do in terms of herbivore management.

October 20, 2021: Last Mariposa Farmer's Market of the Year

MNP ended a very successful season at the Mariposa Farmer's Market. We met quite a few new people, helped out many new customers, and more than doubled our sales compared to 2020. We will be on vacation from the end of October through the first two weeks of November.

November 17, 2021: Native Plant Garden at Mariposa History Center

MNP provided plants for the Mariposa History Center, a project establishing a native plant demonstration garden in the front yard of the museum. The selection of plants was provided by the local Southern Sierra Miwok Nation, based on plants that the tribe used historically. About two dozen local community folks came to help with planting, including History Center staff, UC Master Gardeners from Mariposa County, the Southern Sierra Miwok Nation, school children from the Sierra Foothills Charter School, and Mariposa Native Plants. We dropped about 50 plants into the ground, and we were done in two hours (thanks to the numerous helpers armed with shovels!).

November 29, 2021: Heartleaf Milkweed Survey of Southern Mariposa and Eastern Madera Counties

MNP IT Manager Ron Allen toured southern Mariposa County and eastern Madera County with Diana Magor of the California Department of Fish and Wildlife. Diana was interested in the growth habits of local Heartleaf Milkweed (Asclepias cordifolia), the soil types in which this plant grows, and how large the plants can grow.

December 31, 2021: Sold out: Heartleaf, California, and Woolly Milkweed seeds

We have sold out our stock of seeds for these popular plants. Due to the drought and the River Fire in southern Mariposa and eastern Madera Counties in 2021, our seed collection was rather poor. We have had some good, wet weather so far in the month of December, and we're hoping that the local milkweeds will have good follicle production in the summer of 2022.
