Van Gogh Immersive Experience

Swirling sunflowers and starry nights, vibrant colors, familiar scenes - repeatedly coming into focus and fading into paint smears. It's music, motion, emotion, familiar paintings, but animated instead of static. It's hard to describe the Van Gogh Immersive experience - you really must experience it!

Immersive Van Gogh Exhibit in San Francisco 

My husband surprised me with tickets back in January (pre-vaccine, when it didn't seem like we would ever return to normal life). We're both fans of the artist, Vincent Van Gogh, and have read books about Vincent and his brother, Theo, watched movies about his life, and visited the Van Gogh Museum in Amsterdam.


Enjoying the countryside

Van Gogh Immersive is showing in major cities all over the United States. In San Francisco, masks are required, and large circles on the floor recommend good social distancing. Benches, a platform, and floor space provide many vantage points. The projected art, sound track and 3D and 2D animation bring the story to life. They worked together to evoke the turmoil and emotions that Van Gogh may have experienced as he created, struggled to survive, and dealt with mental illness.

Afterwards, my husband and I had a delicious brunch at Mama's Royal Cafe in Oakland, with lively conversation about what we had experienced. Immersive Van Gogh was the perfect experience for appreciating art and culture, and easing us back into normalcy. I highly recommend the exhibit for both.

Bringing Back the Natives: 2021 Update

So many gardens, so little time! I've been thoroughly enjoying visits to many East Bay gardens, via Bringing Back the Natives virtual garden tours. For the second year in a row, the annual event is being hosted over Zoom and YouTube. I'm amazed at the creativity with which people have shared their gardens. See Bringing Back the Natives: 2021 Kickoff for the basics. 

Former lawn, now planted in natives

The gardens are beautiful - some are very small, others are like parks. Most try to work within the framework of microclimates, low water usage, and native plants. In many of the tours you can hear and see evidence of the birds, bees, and wildlife that are attracted to the gardens.

I've especially enjoyed the emphasis on native plants that attract butterflies, moths, and birds. Several plant lists are posted on the Douglas Tallamy Resources web page, and the Gardening Info web page. The plant lists are a great resource for finding the right plants for your garden. Most plants are available in native plant nurseries in the San Francisco Bay Area. Some presenters noted that even a few local "box stores" provide native plants in a limited way. It's a start!


Ground covers as an alternative to lawn

It's not too late to sign up for the 2021 garden tours. The last event is scheduled for Sunday, May 23, from 10:00 - 3:00. To learn more about registration, the speakers, and the tour schedule for Sunday, see Agenda & Welcome. To see a list of garden tours by city (especially useful if you are interested in your microclimate), see the 2021 Gardens page. The virtual tours are free, but donations are appreciated. Hope to "see" you online!

Dye Project: Camellia Petals

Welcome back to season three of Plants to Dye For! Last year we experimented with some beautiful historical dyes from around the world - madder, cochineal, and logwood.The colors were rich and vibrant shades of red, violet, and purple (see Plants to Dye For (2020): Wrap Up for a recap). This year we're going back to the land, to see what colors the plants on our property might yield. As I mentioned in another article, I'm expecting many shades of brown. But, who knows!

Today I am dyeing with camellia flowers, from shrubs that grow on our residential lot. Several shrubs produce pale pink flowers; and a couple others produce red (or reddish pink) flowers, so I'm doing a batch of each. Research on the web indicates that camellia pigment can produce pale shades of brownish pink, depending on the mordant. The camellia (Camellia japonica) is native to eastern and southern Asia, from the Himalayas east to Japan and Indonesia, but also grows here in the San Francisco Bay Area. 




For this project I used basic dye equipment, and a well-ventilated workspace. I used a soaking pot, a dye pot, a heat source, and a candy thermometer to keep the dye bath at a consistent temperature. I also used a strainer and cheese cloth to remove the petals from the dye bath. Supplies included:

  • Camellia petals
  • Sea salt
  • Ferrous sulfate
  • Lemon
  • A gallon of water (+ more as needed)
  • Prepared cotton fabric (scoured, gallnut mordant, and alum brightener)
  • For safety, wear a face mask when working with powders, and rubber gloves when working with soda ash, which is caustic.

Cotton hankies (large and small), napkins, and dishtowels


The Weight of Fabric for each batch is about 259 grams (9 ounces). I typically dye dish towels, but this year I’m expanding to other cotton items. For each batch I used:

  • 2 dish towels - 154 g (4.9 ounces) 
  • 2 napkins - 50 g (1.76 ounces)
  • 2 large hankies - 35 g (1.2 ounces)
  • 2 small hankies - 20 g (.7 ounces)


Batch 1 – Pink Petals (A Bust)

For the first batch, I used pink camellia flowers, and followed instructions from Sara K. in her article, Camellia Dye. I collected about 12 ounces of pale pink camellia flowers from our yard in mid-February. Since the Weight of Fabric was 9 ounces, the WOF% was about 130%. The supplies for the first batch include:

  • Pink petals: 340 grams pale pink camellia flowers (12 ounces)
  • Sea salt (2 teaspoons)
  • 1/2 lemon (juice and rind)
  • A gallon of water (plus)
  • Prepared cotton fabric

Pink camellias

I followed my typical extraction method. The pale pink petals were lovely and the dye bath was promising. It seemed to indicate that we were on track for a pale brownish pink. I soaked the fabric for about an hour, in the dye bath (I typically soak overnight). I rinsed the fabric thoroughly in cool water, washed, and hung to dry. But, instead of any shade of brownish pink, the fabric remained creamy white. No color at all! I had at least expected a pale tan color, based on the dye bath color.

Experiments can lead to disappointment. But, like Edison’s 2000-plus light bulb experiments, sometimes you discover what doesn’t work!

Colorless results!


Batch 2 – Red Petals (A Success)

For the second batch, I used red camellia flowers. I reused the previously dyed fabric, which was already prepared, and just washed it in Synthrapol. This time I collected about 28 ounces of camellia flowers. The Weight of Fabric was also 259 grams (9 ounces), so the WOF% was about 300%. I gathered the flowers in our yard throughout March, and froze them to preserve the color. Camellia petals turn brown very quickly, but I included the brown petals anyway, thinking they may still have pigment.

Red camellias (or deep pink)

I also decided to use ferrous sulfate as a modifier. Modifiers change the color of the dye. Ferrous sulfate produces a “grayish” version of a color. We’ll learn more about modifiers at another time. Supplies for the second batch include:

  • Red petals: 793 grams red camellia flowers (28 ounces)
  • 1/4 - 1 teaspoon ferrous sulfate
  • 1/2 lemon (juice and rind)
  • A gallon of water
  • Prepared cotton fabric

Ferrous sulfate crystals (food grade)


Extract the Dye

First, extract the dye, using our basic process:

  1. Add petals and lemon to the dye bath.
  2. Simmer for one hour.
  3. Soak petals.
  4. Strain the petals.

Rinse petals and pull them apart. Add the petals to a gallon of water in a stainless-steel pot. Stir in juice of 1/2 fresh squeezed lemon and the lemon rind. Bring to 180-200 degrees, and simmer for an hour. Soak petals and lemon rind for three days.

Simmer for an hour, then let soak for three days

Strain petals out of dye bath using cheesecloth and a strainer. Return dye bath to the stainless-steel pot. The resulting liquor is pale pink/orange. It smelled like an herbal tea.

Dye the Fabric

Then, dye the fabric using our basic process:

  1. Add 1/4 - 1 teaspoon ferrous sulfate and wet fabric to dye bath.
  2. Heat dye bath and simmer for an hour.
  3. Soak fabric in the dye bath.
  4. Rinse and hang to dry.

Add fabric to dye bath, heat, and simmer for an hour


Add ferrous sulfate to the dye bath and stir well. Add wet, prepared fabric, and simmer for an hour, keeping the temperature between 180-200 degrees. Stir periodically to make sure dye is distributed as evenly as possible.

Squeeze out fabric

Rinse until water runs clear

Let soak for an hour or overnight. Since I love saturated color, I let it soak for three days this time. Squeeze out excess dye from the dish towels. Rinse the dish towels in cool water until the water runs clear. Run the dish towels through the washing machine rinse and spin cycles, using cold water. Let the towels air dry. Two weeks later, wash the towels in pH neutral soap, like Synthrapol, and hang to dry.

Hang fabric to dry

Grayish brown with hints of pale lilac

The resulting color is a soft grayish brown, with hints of pale lilac in some light. After reading How to Use Iron Powder below, I'm curious, whether the red camellia pigment contributes any color at all, or does the color result from the mix of tannin mordant (oak gallnut) and ferrous sulfate.

Plant Aquarium: Toyon

The toyon hedge in our lower yard shields us from the sights and sounds of a busy street during rush hour, and is typically alive with bird sounds. It's spring and the blossoms are just getting started. Later the bushes will be filled with white flowers, followed by bright red berries.

 

H. arbutifolia with the start of new blossoms

Toyon (Heteromeles arbutifolia) is a common perennial shrub native to southwest Oregon, California, and Baja. It can be found in coastal sage scrub plant communities, the chaparral, and mixed oak woodlands. It is in the Rosaceae family, and is the only species in the Heteromeles genus.


Cluster of white toyon flowers in spring

The shrubs grow to 6-16 feet tall (2-5 meters), and can live from 100-200 years. The leaves are evergreen, alternate, and sharply toothed with short petioles. The flowers are small, white, and arranged in terminal clusters. The berries are bright red and festive during the fall and winter holidays.


Dense foliage and red toyon berries in fall

Toyon survives on very little water, and is less of a fire hazard than some chaparral plants. They are visited by butterflies, and the fruit is eaten by birds (mockingbirds, robins, cedar waxwings, and hermit thrushes) and even mammals. Native Americans used the leaves, bark, and berries for medicinal purposes, including Alzheimer's. We are visited by many birds in our yard, and the dense hedge provides them sanctuary.
