Ecojustice Camp comes to Cohasset

I teamed up with Ngoc Dupont and Matt Mulder, two professional educators, to bring the Ecojustice Camp concept to the South Shore of Boston last week. We didn’t have the best of weather for the camp, with rain showers almost every day, and a tornado alert for early Friday morning. The tornado alert meant that we didn’t camp at Wompatuck State Park, but instead camped at the Parish House of First Parish (where there was a full basement we could retreat to if necessary). Yet in spite of the weather, we had a blast.

We’ve posted photos from the past week on the camp website. Since we only have permission to post photos from camp on that website, you’ll have to click here to see them. The photos will give you an idea of the range of camp activities — from cooking outdoors, to whittling, to ecology simulation games, and more.

Natural dyes: pine cones

Carol and I are still investigating natural dyes. At the moment, we’re looking for dyes that (a) we can use with kids, (b) will work well for tie-dyeing cotton t-shirts, (c) are in season right now and can be easily collected by kids, and finally (d) are plentiful (i.e., we’re not going to collect endangered lichens to use as dyestuffs).

It looks like the most promising dyestuff for our purposes is going to be pine cones. They’re in season and plentiful, readily available, produce a pleasing pinkish-brown color, and I found someone who did tie-dye with them.

Carol and I went and collected some pine cones today (on land where we had permission to collect). The recipe for the dye bath says to soak the pine cones for 48 hours (see the recipe below); I’ve got some pine cones soaking now. But because I’m impatient, I also boiled some for a couple of hours this evening, even though this will probably produce a dye bath that makes a less intense color.

Stay tuned for updates on our natural dyeing experiment.

Update, 12 Sept: Follow up post here.

Update, 8 Aug.: I followed the recipe below fairly closely. The cloth emerged from the dyebath a pleasing light tan-yellow color. But nearly all the color came out in the first washing, so that now we have a very light tan-yellow. N.B.: In her book Craft of the Dyer: Colour from Plants and Lichens (Univ. of Toronto, 1980), Karen Leigh Casselman says she got a “warm tan” color from pine cones with “good colorfastness,” but she used alum and chrome mordant; I suspect, too, that she used this dyestuff with wool, not cotton.

We were not encouraged with our experience using pine cones for dyeing cotton. It’s too bad, because where live it’s easy to find plenty of pine cones. We probably would have gotten better results with a chrome mordant, but we don’t want to use chrome with kids because of the toxicity.

Natural dyes from invasives

I’ve been researching natural dyes for textiles, and got interested in the possibility of using invasive species to make dyes. After all, if you’re going to pull up the plants anyway, why not do something with them? Here’s a list of invasive plants in Massachusetts, and also a list of plants likely to be invasive.

I’m still in the research phase, and haven’t actually tried any of these myself. Many of these appear to be recipes for dyeing wool yarn. Nevertheless, here are some possibilities I found:

Other non-native species that can be used for dyeing:

Unfortunately, much of the material I found online is not entirely useful. Some of the webpages linked to above just say that the plant can be used as a dye, but with no indication of mordants, length of time in dye bath, color-fastness, etc. And many of those dyeing are only interested in dyeing wool yarns, while I’m more interested in tie-dye projects for kids (here’s info on mordants for cellulose, e.g. cotton, fibers). Anyway, I’m planning to do some invasive species dyeing myself, and if I do I’ll give some more details.

Joe-pye Weed

Perhaps my favorite fall flower is Joe-pye weed (Eutrochium spp.). There’s something about the color of the flowers and the color of the foliage that gets me, I don’t know why. I often have a strong emotional response to certain colors, and when sunlight catches the dull purple of Joe-pye Weed, I can feel it in my chest. I have no idea why this is so, I just know that it happens.

On a walk this afternoon, I came upon some Joe-pye Weed nest to a rushing stream in the Whitney-Thayer Woods in Cohasset. About a hundred feet of the trail, near one of the crossings of Brass Kettle Brook, was flooded from the torrential rains we had last week. I was teetering along on logs and stones that someone had conveniently placed alongside the trail, when there it was by the side of the trail: those dull purple buds almost ready to burst into bloom.

I’ve been trying to figure out which species of Joe-pye weed this was. I think it’s Coastal Plain Joe-pye Weed (Eutrochium dubium), but I admit that I get confused by the online dichotomous key of the Native Plant Trust (—are the leaf blades triple-veined? —are the stems spotted or streaked with anthocyanin? —what exactly is the shape of the capitulescence?). Admittedly, I didn’t try as hard as I might to figure it out, since the dichotomous key tells me that E. dubium is “difficult to distinguish from related species.” Nor do I really need to know exactly which species of Joe-pye Weed it is — they all have similar flowers which evoke the same emotional response in me.

Coral fungus

I almost stepped on this small fungus — it was maybe two and a half inches tall — when I was out for a walk today. I’m not competent to identify it, but between my field guides and iNaturalist, I’m thinking it’s a coral fungus in genus Clavulinopsis. Not that I’m particularly anxious to learn what species it is. I’m more interested in its weird beauty: delicate little sculptural forms rising up out of the woodland litter.

Declaration of Independence reading

According to tradition, Rev. John Brown, the minister in Cohasset during the Revolutionary War period, gave a stirring reading of the Declaration of Independence from the pulpit of the meeting house to the gathered townspeople not long after July 4, 1776.

I haven’t been able to find out the exact date when Brown read the Declaration to the people of Cohasset. But the Boston Gazette and Country Journal printed the complete Declaration of Independence on July 22, 1776. John Brown had a copy of that printing, and his copy (with his signature) still exists; it was auctioned by Christie’s in 2003. Since Cohasset was a port town, it seems likely that Brown would have received the newspaper by Sunday, July 28. That may be the date on which John Brown read the Declaration of Independence to the town, when people gathered for Sunday worship.

We decided to commemorate the first reading of the Declaration of Independence to Cohasset townsfolk on Independence Day weekend. So we held our reading on July 2 — not historically accurate, but this wasn’t a re-enactment of the original. Instead of having one person read the whole Declaration, in true democratic fashion we had ten readers, beginning with a 12 year old from our Sunday school.

Fifty people showed up, many more than our usual 15-20 people for summer services. This was a true community event, and somewhere between a third and half of those present were not part of our congregation. Our 1747 Meeting House was originally built by the town, and we feel we hold it in trust for the whole town. So we made this a truly non-sectarian commemoration, with no over Unitarian Universalist content.

We had people across the political spectrum, all of whom gathered together to honor the highest ideals of American democracy. It was a surprisingly moving event. We plan to do it again next year.

Tiny flower

Medeola virginiana, sometimes called Cucumber Root or Indian Cucumber-root, is in bloom in the woodlands around Cohasset right now. As the name implies, the small root is crunchy and white and tastes like cucumber — but you kill the plant when you dig it up for the root, so I stopped foraging for it many years ago.

The flower is tiny, maybe a centimeter or two across. It doesn’t look like much until you look at it through a magnifier:

Eco Fest

This afternoon, Eco Fest took place on Cohasset Common, right across the street from First Parish in Cohasset. Four of us — Ngoc, Matt, Carol, and I — staffed a table where kids could make seed bombs.

(What’s a seed bomb, you ask? Make a thin wafer, maybe two inches in diameter, out of some air-dry clay. Put a pinch of potting soil in the middle, add a dozen or so seeds, then fold the clay up around the seeds and soil to make a little ball. That’s a seed bomb. You can toss it anywhere. The clay holds in moisture, and the soil provides a medium so the seeds can begin sprouting.)

Our seed bombs were made with seeds from native plants. When older kids made seed bombs with us, we explained about the importance of native plants, and how native plants can attract a wider diversity of pollinators. Ngoc had a cool book with photos of 50 or so native pollinators, which I showed to kids, pointing out pictures of my favorite native pollinators — metallic green bees (genus Agapostemon).

We had a constant stream of kids coming to our booth, so I never even got to visit any other booths. But I could see there were some interesting groups present. In addition to commercial vendors, I saw booths staffed by the Cohasset High School Green Team, the North and South Rivers Watershed Association, a group providing recycling information, the Cohasset Garden Club, and more. I’m already looking forward to next year.

Citizen science project

Another worthy citizen science project…. Here in New England, the Native Plant Trust trains people to be Plant Conservation Volunteers (PCVs) for the New England Plant Conservation Program (NEPCoP):

“PCVs support professional botanists and State Heritage Programs by gathering vital data in the field. Across the six states of New England, PCVs conduct field monitoring, seed collection, and habitat management. PCVs now number in the hundreds, but as native plant habitats face mounting stresses, we need even more passionate volunteers to help save New England’s native plants.”
