Songlines 2017: widening circles

I live my life in widening circles
that reach out across the world

These words, from Rainer Maria Rilke’s exquisite Book of Hours, are slightly paradoxical because this year we traveled less than any of the other years since we set off on our journey in 2011.  My partner George’s health isn’t up to life on the road at this point, so my songlines this year became widening circles around Greenbrae, California, just north of San Francisco, where there is a whole world to explore. California hosts one of the most diverse native plant populations in the country and is home to snow-capped mountains, oceans, deserts, grasslands, coastal forests. Earlier this year I celebrated this extraordinary mix within easy reach in Wild Abandon: the Mystery and Glory of Plant Diversity.

Californians also care deeply about saving wild places. Half of the state is preserved land, an extraordinary accomplishment. I marvel at the knowledge of native plants and birds I find when meeting lawyers, nurses, teachers, business people on walks and hikes. In May, I joined a bioblitz for the first time. In fact, it was the first time I’d ever heard the word. I wrote about the fun we had cataloging every living thing within a small area of Mount Tamalpais in Blessed Unrest: the Bioblitz. It’s a celebration not only of our day but of the millions of people around the world who are taking actions, large and small, to save and repair the world.

Rilke’s quote comes from one of the highlights of the year: spending three days with the ecological and Buddhist philosopher, Joanna Macy. Her Work that Reconnects helps people to confront their grief at what is happening to the earth, and to renew their commitment to the work they feel called to do. Rilke’s genius has supported her ever since she discovered him when she lived in Germany in her twenties, and her translation of his poetry punctuated our time with her. In The Work that Reconnects: a Weekend with Joanna Macy, I wrote about the extraordinary, moving circle of twenty-eight people, young and old, who gathered to move through Joanna’s spiral of gratitude, grief, and renewal. I found it uplifting, joyous, complicated, loving, inspiring, painful: life distilled into a weekend

Out of the time with Joanna came other circles. There were several landscape designers there, and one of them, Susan Friedman, had a number of native plant gardens on a tour in early May. So, off I went. I described what I found in Retaining Paradise: Gardening with Native Plants, and wrote about a longtime passion: using our gardens to recreate the bird and animal habitat that built-up neighborhoods inevitably destroy. 

Tall thistle (Cirsium altissimo) and bee, Golden Prairie, Golden City, Missouri by Betsey CrawfordJoanna’s workshop was held at Canticle Farm, an urban farm in the heart of Oakland. While we were there, the bees from the beehive swarmed, as they got ready to leave for a new home. This inspired Susan, who’d been thinking about having a hive, to find a class on beekeeping. It had never occurred to me to do such a thing, but when she asked if I was interested, I instantly wrote back, ‘of course.’ I loved our day with the bees, and chronicled it in Treasuring Bees, Saving the World

Rock tunnel along the road in southern Utah by Betsey CrawfordOur life on earth is tied to the health and life of the bees, which can also be said of many things, including dirt. In The Intimate Bond: Humans and Dirt, I treasure its multi-faceted community and innate intelligence, which made it possible for us to evolve and keeps every living thing on earth going. Dirt is not cheap! Much of the urgent need to take care of the thin layer of soil on our planet lies in the endless time frame it takes to form it. Focusing on Utah, where you can literally drive through the planet’s ancient past, I explored its mysteries and consolations in The Solace of Deep TimeBlack crowned night heron in Corte Madera Marsh, Corte Madera, California by Betsey CrawfordIn Greenbrae, I live near a lagoon that attracts a wonderful, shifting community of shorebirds all year. Around Easter an avalanche of ducklings started, family after family of adorableness so acute I was addicted to that walk for three months. This handsome night heron is part of  A Season of Birds, where I describe my happy visits to the vibrant life there — which included an unusual extended family — and honor the necessity and hard work of preserving and reclaiming such lands.

And, of course, I spent the year celebrating flowers. For a few weeks each spring, California is an iris addict’s paradise. I wrote about my feelings for these bewitching flowers in Elegant, Wild, Mysterious: Loving Iris, and suggested that flowers’ ability to inspire love may help save the planet. I discussed the complications of our gorgeous roses in Passion and Poison: the Thorn in the Rose. In early August I explored one of the most joyful flower families on earth in One Big Happy Family: the Asteraceae, and created a gallery to show their beauty and wide diversity

Then, later in August, on a trip to New York, I was able to do something I can’t do in California: stand in a sea of goldenrod. Naturally, that called for celebrating the way this extraordinary explosion of luminous yellow connects us to the heart of nature in The Gold Rush: the Joyful Power of Goldenrod. I also visited an early childhood home, set in a magical green world. I wove my memories and my realization about how deeply that time affected the life I’ve lived into A Girl in the Garden of Eden.

For Halloween I thought choosing ghostly white flowers for Happy Halloween: Ghosts in the Landscape would be fun, and it was. To my surprise, the fun turned out to be exploring why we have white flowers at all, and how their chemistry is related to ours. That post, too, inspired a gallery: Luminous Whites.

The only essay I didn’t write was written by Pope Francis. Laudate Si Repictured is an interweaving of words from his eloquent encyclical on the care of the earth with pictures of our beautiful planet. One of the quotes encapsulates the message I kept finding on my circling songlines this year:

All of us are linked by unseen bonds and together form a kind of universal family, a sublime communion which fills us with a sacred, affectionate and humble respect.

Human and seagull footprints in the dirt in Kenai, AlaskaLoving the place we find ourselves will give us the strength and vitality to preserve it. Damage to the world and its people will be slowed and salvaged by love: for the earth, for our fellow creatures, for its waters and air, for the dirt under our feet, for the wondrously intricate web of all beings of which we are a part.  A profound understanding of our inherence in the natural world– the idea that we are the planet, not on the planet — is a gift we give both the earth and ourselves. 

I wish you all a new year of love, commitment, and beauty.

One big, happy family: the Asteraceae

A sunflower (Helianthus annuus), a memeber of the Asteracea family, In Cape Breton, Nova Scotia, Canada by Betsey CrawfordI took the picture above six years ago this month, standing in a field of sunflowers on Cape Breton Island on the east coast of Canada. It was the first place we went when we started the journey that has taken us to so many wonderful places. I’ve never forgotten the joy of standing in that field, completely surrounded by the happiest of flowers, growing with wild abandon toward the August sun.

With almost 24,00o species, the Asteraceae family is vast and exuberant. It’s literally everywhere you go, except Antarctica. The accompanying photos range from Alaska to the Anza Borrego Desert in southern California. They reflect one of the family’s strengths: the ability to thrive in many different environments, whether hot or cold, dry grassland or wet marsh, in alpine meadows or among desert cactus. Some are important commercially: sunflower, safflower and canola oils. Camomile and echinacea tea. Artichokes, lettuce, tarragon, radicchio, endive. One shrub even produces a form of latex. The horticultural market depends on many of them.

The most familiar asteraceae configuration is the sunflower and its relatives: a central circle of disk florets, surrounded by a crown of ray florets that look like and act like petals, attracting insects to pollinate themselves as well as the less showy disk flowers. The family name comes from these composite forms: aster derives from the Latin word for star. But there are a variety of other structures. Some, like the thistle and the arnica below, are discoid, with disk but no ray flowers. Others, like the dandelion, are ligulate, with no disk flowers and ‘petals’ of strappy ligules.

As a group, they tend to develop a fluffy seed head, a pappus of filaments that originally surround the base of the ovary, and grow longer as the flower goes to seed. With their feathery attachments, seeds are easily dispersed by wind, which helps account for the ubiquity of yarrow, fleabanes, dandelions, asters and other family members. Some seeds have hooks on them and spread out by attaching themselves to animal fur or clothing.

What looks like an individual flower is an inflorescence, a bowl-, vase- or cone-shaped capitulum, holding its lovely arrangement of hundreds of ray and disk florets. The capitulum is held by green bracts, or phyllaries, sometimes many layers of them, constituting an involucre. When you eat the bud of an artichoke flower, you peel off, dip in melted butter, and then eat one phyllary after another, until you get to the heart, which is the capitulum containing the disk flowers. The phyllaries can be plain or beautifully sculptural. Their differences, in number, shape and position, are often a key to identifying close species. 

Analysis of fossil pollen found in Antarctica dates the Asteraceae to 80 million years ago, when the continent was still part of Gondwana, before it floated south to the icy pole. Species were lost during the K-T extinction, which killed the dinosaurs around 66 million years ago. But those that survived thrived and multiplied during the great flowering of the warm Late Paleocene and Early Eocene epochs, as did every other plant family. The asteraceae in turn benefitted their pollinating insects, and were especially important to the evolution of bee species.

They are a pollinator’s dream: one landing, up to 1,000 flowers. The sunflower, our biggest and most dramatic North American native asteraceae, dedicates a most intriguing and charming trait to bees and other pollinators. It starts with buds and young flower heads, still covered with their green, photosynthesizing bracts, following the sun over the course of the day. At night, they work their way back toward sunrise, moving faster near the solstice, and more slowly as the nights grow longer.

This cirdadian heliotropism is driven by growth hormones that spur growth on the east side of the stem during the day, lengthening that side, and tilting the flower head toward the west. At night, another hormone spurs growth on the west side, moving the flower to face east by morning. In experiments that interfere with this sun tracking, plants quickly lose mass and leaf surface, cutting down on photosynthesis and thus vitality and size.

Their sungazing stops at maturity. The ‘clock genes’ turn off, leaving entire fields of sunflower heads facing east. That way they are warmed early in the day, making them five times more likely to be visited by pollinators than experimental plants arranged to face west.  And there are lots of pollinators: bees, butterflies, moths, flies, wasps, wind, and, in South America, birds. With their warm, open faces offering almost unlimited opportunity for fertilizing, reproduction becomes very efficient, which explains the diversity and worldwide habitat of the family.

Standing in a field of sunflowers, or prairies of thistles, coneflowers and goldenrods,  I am not only surrounded by the sheer exuberance of vividly colored, beautifully shaped flowers, with their attendant bees and butterflies. I am surrounded by a long history of carefully ‘chosen’ evolutionary changes that remain mysterious despite all the genetic information we can now gather about plants. Why so many yellows? And why pink, or white? Why feathery leaves on one family member, big chunky leaves on another? Why is this one so tiny, and this one gigantic? Why a cone on one, a bowl on another? This heavenly exuberance of form and color is a delightful mystery.

In that sunlit field I’m also surrounded by a form of life — the flowering angiosperms with their nutritious fruits — that may well be responsible for me, a member of a much later species, being able to stand there at all. That nourishment helped my forebears to develop the eyes and consciousness to celebrate the wonder around me. That may even be the point of evolving me at all: a way for the universe to contemplate its glories.

Relishing the sunny warmth of a summer day, drinking in the beauty and vitality of the flowers around me, grateful for our shared history and destiny — these are moments of transcendence that make life rich and fulfilling. Our beautiful world makes them so available, but we too often rush by. Even when we stop, we feel we must quickly return to the practical tasks that make life possible. But our world is always there, waiting to be treasured. Waiting for the eyes and ears it has gifted us with to turn toward these great and beautiful mysteries. “Life is this simple,’ theologian Thomas Merton wrote. “We are living in a world that is absolutely transparent and the divine is shining through all the time.”
