Plant Hunters: Amy Patten

What about modern plant hunters? Earlier this year we looked into the lives of two plant hunters that collected in the Western United States, David Douglas (1799 - 1834) and Lester Rowntree (1879 -1979). Plant hunting, or plant collecting, refers to the acquisition of plant specimens for research, cultivation, or as a hobby, and has occurred around the world for thousands of years. In 2020, I was intrigued by two articles from the California Native Plant Society (CPNS). One article announced Amy Patten as the Society's new Rare Plant Treasure Hunt (RPTH) coordinator in California and the other described her as a Conservation Champion. Both were intriguing, because they cast a light on what a modern plant hunter might do.




One of the goals of the Rare Plant Treasure Hunt is to resurvey old records of rare plants in California. The surveys were done in the 1970s, 80s, and 90s and include written site descriptions, since GPS was not widely available. As RPTH coordinator, Ms. Patten leads a team of fellow botanists and volunteers to scour California for rare and endemic plants. Some detective work is required to locate the sites. The team updates the records with current information and precise locations, and sometimes gather seeds or plant tissue. They have access to land that the public cannot, and often require special permits.

For a flavor of modern plant hunting, see the Treasure Hunting after the 2020 Fires presentation (above), which recounts burn area surveys of the SCU Complex and CZU Complex Fires. The SCU Complex fire occurred in the Diablo range (around marker 19:45) and the CZU Complex fire occurred the Santa Cruz mountains (around marker 35:38). I especially liked hearing about the team's adventures locating sites based on old descriptions, and seeing photos of the rare and endemic plants they encountered, some of which only live in a particular region or site. Both provide an insight into the modern plant hunter's motivation - conservation.

Dye Project: Indigo Resist Dyeing

All this year, we've been learning about dyeing with indigo. Last time we tried overdyeing previously-dyed fabric with indigo to see what colors we would produce (see Indigo Overdyeing). The shades of green were inspiring! This time we're using several resist dyeing techniques with indigo dye. This project was photographed on the second day of a four-day dyeing session, and the dye vat had lots of color. Note that this article builds on our previous indigo dye projects, so please see related articles for details (Mixing the Indigo Dye Vat and Basic Indigo Dyeing).

Resist dyeing is a traditional way to dye textiles to produce patterns. The best-known methods include Shibori, tie dye, batik, and ikat. Various methods are used to “resist” or prevent dye from reaching the fabric, thus creating the pattern and ground. Common resist materials include wax, mud, and starch paste; and resist methods include binding, twisting, and stitching the cloth. You may have tie dyed a tee shirt as a kid. The tightly bound rubber bands provided the resist. 


Equipment and Fabric

Equipment for this project includes an indigo dye vat, water for pre-soaking and rinsing, a tray to hold dyed fabric, latex gloves to protect hands, and prepared work areas for dyeing and drying the fabric. 

For fabric we're using:

  • Cotton dish towels
  • Cotton and linen fabric pieces
  • Cotton handkerchiefs

All fabric was scoured and some reused fabric was mordanted. The latter is not a requirement, since indigo has a high tannin content. To prepare the fabric, were using these resist materials:

  • Rubber bands
  • Glue
  • Wood and acrylic tiles
  • Canning jar lids
  • Binder clips
  • and more!


Basic Dye Process

We’ll follow these basic steps:

  1. Presoak the prepared fabric (about 20 minutes).
  2. Dip fabric in the dye vat (I used one dip for about a minute).
  3. Squeeze out excess dye, and then set fabric aside to oxidize (about 20 minutes).
  4. Remove bindings, rinse, and hang to dry.
  5. In about a week, launder in mild detergent and hang to dry.

These steps are iterative and flexible.

For Safety: Keep the indigo dye vat out of reach of children and animals, and store the dye with the lid sealed. Also, never use utensils that have been used for dyeing to prepare food.


Resist Dyeing: Shibori

Shibori is a Japanese manual resist dyeing technique used to create patterns that spread unevenly across the fabric. The uneven patterns are part of the charm.

Shibori supplies include:

  • Wooden and acrylic tiles
  • Flat canning lids or ‘flats' (not the screws)
  • Rubber bands
  • Binder clips


Preparing fabric for Shibori 

To prepare the fabric, fold it and clamp it between tiles and flats, like a sandwich. I found it useful to iron the fold lines in place first to ensure even sections. Where the tiles or bindings touch the fabric, the dye does not attach. Follow the basic dye process. 


Soak prepared fabric in water

Dip fabric in indigo dye and set aside to oxygenate

Remove bindings and set aside to oxygenate

Rinse fabric and hang to dry


Resist Dyeing: Tie Dye

Tie dye describes several resist dyeing techniques and the resulting dyed products. The tie dye process includes: (1) folding, twisting, pleating, or crumpling the fabric; (2) binding with string or rubber bands; and (3) applying dye or dyes.

Tie dye supplies include:

  • Rubber bands of various sizes
  • String
  • Glass marbles


Preparing fabric for tie dyeing

To prepare the fabric, bind it with rubber bands, string, or a combination. In some fabric pieces, I created one or more pouches of glass marbles in several places. We’ll see the results later. Follow the basic dye process.

Resist Dyeing: Batik

Batik is an Indonesian technique of wax-resist dyeing that is applied to cloth. Batik is made by drawing dots and lines of the resist or by printing the resist with a copper stamp. The wax resists dyes. 

The dyer can color selectively by (1) applying wax; (2) soaking the cloth in one color; (3) removing the wax with boiling water; and then (4) repeating the process for additional patterns and colors (similar to print making).

 

Elmer's Washable glue and a design pattern

For batik supplies, I am using Elmer’s Washable glue as an alternative to wax. If it turns out that I want to try the traditional wax method, I can invest in the proper equipment.


Creating a simple chevron pattern with glue resist

To prepare the fabric, squeeze the glue onto the fabric to create a pattern. For the dishtowels, I created a simple chevron pattern for one, and a squiggle pattern for the other. For the handkerchief and the cotton and linen fabric pieces, I experimented with shapes. As with anything, it takes some time to develop a technique for working with new materials.


Prepared fabric for batik

I dipped the fabric in the water to presoak, but quickly realized it was softening the glue. I pulled the fabric out immediately. Soaking is not a good idea for glue resist! Otherwise, follow the basic dye process. One exception is that you'll need to remove the glue once the dye has set. 


After you dye, soak the fabric and scrape off the softened glue

To do so, soak the fabric in water to soften the glue (at this stage, it is OK). The fabric was quite stiff from the glue that spread from the design to its surroundings during the quick pre-soak. Scrape off the softened glue with a plastic spoon or your fingernail. Then rinse and hang to dry as you usually would.


Rinse and hang to dry


Rinsing, Washing, and Hanging to Dry.

In about a week, launder the fabric in cold water, using a mild detergent like Professional Textile Detergent or Synthrapol. Hang to dry.


Reviewing the Results

Let’s look at the outcome from our resist dyeing experiments with indigo dye.


Left to right: Shibori, tie dye, and batik (resist dyeing)


Shibori Results

You can create such interesting patterns with just folding and binding fabric for Shibori dyeing. Following are the results and some observations. 


Shibori creations

Not much color was absorbed by the dish towels. The large tiles reached almost to the folds. Possibly folding the fabric into a larger size would help (or using smaller tiles), so that more fabric extends beyond the tiles to absorb dye. A longer presoak in water may also help, as well as a longer dip in the dye.

I especially liked the round canning lids for variety. Square tiles placed on the diagonal also produced a roundish pattern. The tiny and small tiles were fun to work with. 


Clockwise from top left: linen and round flats;
small handkerchief and small tiles; 
dishtowel with large square tiles on the diagonal; 
large handkerchief and medium tiles; and

Sometimes you just need to try something to see how it works. Now that I’ve seen the results, I can think of more ideas to try!


Tie-Dye Results

I like the variety of patterns produced by binding the fabric with rubber bands and string.


Tie dye creations

I also liked experimenting with binding packets of glass marbles with rubber bands, and seeing the interesting patterns it produced.


Top: marble tie dye detail.
Middle: cotton and rubber bands, cotton dish towel and marbles, and cotton with bindings.
Bottom: cotton and rubber bands, linen with rubber bands, and cotton with bindings.  


The thread and rubber band experiments reminded me of the Ikat examples I saw online, where fabric is tightly twisted and then dyed. I like the spidery patterns that different kinds of bindings produce.


Batik Results

Elmer’s glue was a great way to experiment with batik, without investing in wax melting tools. 


Batik creations

In retrospect, I may have used too much glue in my patterns. The glue remained tacky for a long time and may not have dried thoroughly. When I hung up some pieces to dry, the glue ran, creating part of the pattern.

Soaking the fabric before dyeing was a mistake. The glue started to soften and spread. It resulted in some interesting patterns and a partial blocking technique. Remember that imperfection is part of the charm of hand dyeing!

I’m pleased with the results and hope to try more experiments with glue, and eventually with wax.

That brings us to the end of our adventure of dyeing with indigo. I tried a lot of experiments and love the magic of blue!

Birthday Flowers: Aster

The birth flowers for September are asters and morning glories. I'm focusing on asters, for their star-like form and multitude of species (around 23,000 of them). The colors range from white, to yellow, to shades of pink, red, and purple. Plants produce an abundance of daisy-like flowers with a central disk (frequently yellow). Asters symbolize love, wisdom, faith and patience, and are often associated with the wonder and enchantment of the stars.

Petal color can convey more specific meaning to the recipient of your aster bouquet:

  • White - purity, innocence, and new beginnings
  • Yellow (China) - happiness and good fortune
  • Pink - love and sensitivity
  • Red - undying devotion
  • Purple - spirituality, wisdom, and royalty


White asters to signal a new beginning 


Asters (Asteraceae) grow from 1 - 6 feet tall, depending on the species, and have lance-shaped linear leaves that are usually arranged in an alternate pattern. They typically bloom in late summer and early fall, at a time when many flowers are spent. They prefer full sun and well draining soil. Their history dates back to ancient times, and they have been enjoyed for their beauty and appreciated for their medicinal properties to treat coughs, colds, digestive issues, and muscle aches. The simple beauty of asters is sure to bring a smile to anyone's face, including your own.

Summer Heat at Filoli

Over the last decade, my Aunt Char and I have visited Filoli in Woodside, California in all four seasons and at Christmas. The gardens, grounds, and home are always beautiful, stately and inspiring, and there is always something new to see. We recently visited Filoli in the midst of a summer heat spell to celebrate Aunt Char's birthday. As an added treat, my cousin Chris (of Glam Camper fame), and his wonderful wife, Nancy, were in town and joined us on the expedition. On the day we visited, staff and volunteers were preparing for an evening fundraising gala, so we caught glimpses of the preparation throughout our visit.

Ready for our house and garden tour

The temperature hovered in the low nineties, so we were in shade-seeking mode throughout our visit. We lingered within the house for our self-guided tour and enjoyed the decorating changes since our last visit to Filoli for the holidays in 2019, and the beautiful floral arrangements from the gardens. Chris and Nancy pointed out some interesting details about the unique woodwork that appears throughout the house. We also appreciated the cooler temperature and relief from the midday sun.

The grounds were beautiful in layered shades and textures of green. Begonias, coneflowers, and hydrangeas were blooming in full force when we visited, and the dahlias were just ramping up.

The Garden House is one of my favorite buildings. It would be the perfect space to savor my morning coffee and read the newspaper and periodically enjoy the landscape through the arched windows. For our visit, we enjoyed a break from the sun and the beautiful views of the garden.


Garden House is a favorite place

A shady respite in Garden House

By the time we  toured the Cutting, Vegetable, and Production Gardens, the sun was not as high in the sky and a marine breeze was stirring. Resting in the shade to survey the beauty was still part of our strategy.

Hydrangeas of all colors

The hydrangeas were so beautiful and colorful! The flower color is partially determined by the soil's pH (acidic soil yields blue or lavender, and alkaline soil yields pinks and reds). The gardeners must modify the soil to produce such a variety of color. (We had time to ponder this on the shady path). 


Black-eyed Susan flowers

My husband, Rick, joined us at Fentons Creamery and Restaurant for dinner and ice cream creations, and conversation about our visit to the garden. The atmosphere at Fentons was very festive that night, with lots of birthday celebrations (we fit right in with Aunt Char's birthday). Later we regrouped at our home for conversation in the cool of the evening. What a great day, filled with beauty and wonderful people!
