Plant Story-- The Under-Appreciated Parsley

Parsley doesn't get much respect. Restaurants garnish plates with a sprig of parsley, but diners rarely eat it.

And yet, parsley has a long history as a breath-freshener. And will help settle your stomach.

A Glimpse of Northern Chile

Atliplano. eastern Chile
Altiplano, Chile
Northern Chile can be "down" in the Atacama Desert at 7,900', or on the Altiplano, averaging 12,000' above sea level, or higher, in the surrounding mountains. This is the second part of my description of a trip to northwestern Argentina and northern Chile, begun in last week's post (link).

A Glimpse of Northern Argentina

North and west of Buenos Aires, Argentina becomes more and more tropical and then rises toward the Altiplano and the Andes. The rainfall drops to a few inches a year, which fall during the hot summer.

Plant Story--Sticklleaf, Mentzelia nuda

Mentzelia nuda, a short-lived perennial of sandy sites in the western plains, is called stickleaf and blazing star. My personal name for it was "quitting-time flower."

Plant Story--Rhubarb, A Curious Food

Rhubarb is an odd food plant: we only eat the leaf stems.

rhubarb
Rhubarb. Only the leaf stems are harvested and eaten!
I guess the same is true for celery, but celery leaves and roots are edible. Rhubarb leaves could kill you. Rhubarb roots were a significant traditional herbal medicine all across Eurasia, often as a purgative. So this food plant is raised only for its leaf stems (technically, petioles).

Plant Story--Ragweed, Ambrosia, an American Wildflower

Ragweed. Makes you think of allergies, right?

ragweed, Ambrosia
ragweed, Ambrosia
But my title says "an American wildflower."

And it is.

The ragweeds, the genus Ambrosia, in the sunflower family, Asteraceae, are all endemic to the Americas. Of the 22 species native to North America, only five are widespread (see USDA maps). But two species are in every one of the lower 48 states, annual ragweed Artemisia artemisifolia, and western ragweed, Artemisia psilostachya. They look very similar. The annual ragweed has always been a plant of disturbed areas, spending the winter as seeds, needing relatively open conditions to prosper during its one year of life. Human disturbances have given it many more places to grow. The other widespread ragweed, western ragweed, is a perennial, and is found in native ecosystems all across the United States.

Ideas from Japanese Gardens

I took a garden tour in northern Japan this past June (blog). Not only did it make me see my plants as poorly trimmed (see earlier blog), there were lots of useful ideas.

Migrating Butterflies Love Rabbitbrush

"Kathy, I was at your plant walk Saturday at Devil's Backbone and today, there are hundreds, maybe thousands of butterflies there!"

painted lady butterflies, Devil's Backbone, Loveland, CO

I'd just picked up the phone in mid morning, Sept. 22. To be alerted by Sandy to the butterfly migration.

I'd read something about a butterfly migration in the Denver Post : more than the usual number of painted lady butterflies moving south along the Colorado Front Range.

I went to see for myself.

Hawaiian Tea

Tea from Hawaii?

Tea, Camelia sinensis, is a major tropical crop. Hawaii is the only state in the United States with a tropical climate, so it shouldn't come as a surprise that Hawaiians are growing tea. But it did!

Plant Story--Rubber Rabbitbrush, Painting the Landscape Gold

rabbitbrush

Every fall, the Rocky Mountain foothills turn golden as the very-abundant rubber rabbitbrush, 
Ericameria nauseosa, flowers. It is a spectacular display, coming at the end of summer when most plants are through folowering.

The Late Season Flowers

rabbit brush, not quite in flower
Rabbitbrush in August
I planned to write about rabbitbrush, Ericameria nauseosa, but on August 23, the plants weren't flowering at all. I went back August 31. On Aug. 31, I could have gathered a bouquet from a hillside of covered in rabbitbrush but fewer than one in 20 inflorescences had open flowers. It will be a good flowering year, but the flowering season has hardly started.

Who would have thought that late August would be too early for flowers?

Visiting Toronto--McMichael Center for Canadian Art

In Toronto on a Sunday morning in June, we caught the Art Bus to the McMichael Center

McMichael Center for Canadian Art

Just north of Toronto in Kleinberg, the Center was created in 1952 to display Canadian art, from both indigenous people and European Canadians. Although there were pieces by Canadians on not particularly Canadian subjects, the focus was art depicting Canada. Since Canada is a country of glorious natural beauty, it was a treat for a botanist and ecologist.

Visiting Ontario, Canada--Plants of Toronto

In 2017, Canada is celebrating its 150th anniversary. I took a tour of Toronto with Road Scholar link

Toronto is not only the city with the largest population in Canada (2.7 million people), but it is the 4th largest city in North America, after Mexico City, New York, and Los Angeles. Greater Toronto has 7 million people. It sits along the north edge of Lake Ontario, so for Canada it is in the far south. Lake effects from the Great Lakes keep Toronto's climate mild, moist and unpredictable.

Toronto

For me it is always a botanic tour, so here is a brief look at Toronto's plants.

Datura sp.
Datura with flowers opening: research plants can be very beautiful
After the Garden Blogger's Fling, which featured gardens around Washington, D.C.,  I attended the Botanical Society of America meetings, within the excellent facilities of the Omni Hotel, Fort Worth, Texas. The first meeting was full of bright flowers, garden design and the heat and humidity of northern Virginia in June (link). The second showcased of the latest ideas, photos of exotic locations and the dark and chill of air-conditioned conference rooms.

Plant Story--Curly Dock, Uses and Folklore

Curly dock, also called yellow dock, Rumex crispus, is a sturdy plant in the buckwheat family, Polygonaceae, native to Eurasia and now found all over the world. (See previous blog post, link.)

curly dock, Rumex crispus
curly dock, Rumex crispus
                                    
The Greeks and Romans both used it medicinally. Seeds soaked in water treated dysentery. The root was boiled in vinegar and applied to skin ailments and to ease itches. Served in wine, dock soothed aching teeth. It was considered an effective treatment for goiter, which to the Romans meant any swelling in the throat area. One common goiter treatment was to hang a piece of dock around the patient's neck like an amulet.

Throughout Europe, rubbing dock on the skin was an antidote to stinging nettles. Since both were common in wet areas, it was usually available.

Modern herbal medicine doesn't support these uses very strongly: for example, although dock soothes the skin but there are better treatments.

Dock leaves were traditionally added to tobacco pouches to keep the tobacco moist. They were also boiled and added to poultry feed. The stems, after boiling and salting, were woven into baskets. 

                                    curly dock, Rumex crispus

Europeans used the seeds in money charms. They were soaked in water and the liquid was sprinkled throughout the shop to bring customers. 

Seeds were tied to a woman's left arm, or carried there, to help conceive a child. 

People ate dock. The whole plant is edible, as are other docks and sorrels (species in the genus Rumex; not, though, plants that share only a common name such as burdock (Arctium) and wood sorrel Oxalis). The catch is, not all docks taste good. They range from too tough or too stringy or too acidy, on over to delicious. Foragers often recommend curly dock as best-tasting of the docks. 

All docks have some oxalic acid. In large quantities oxalic acid is toxic. Plants for a Future says, "People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition. Avoid during pregnancy & breast feeding." (PfaF). 

In moderate quantities, oxalic acid imparts an attractive acidy, lemon-like flavor. Many common foods such as spinach, contain oxalic acid (more info). An Indian woman told H.D. Harrington that she especially liked that curly dock "already has the vinegar on it." (pp.91-92).

                                   curly dock, Rumex crispus

Before you munch a leaf along the hiking trail and write it off as nasty, read foraging books such as Thayer or Harrington, or recipes from the web (see references). Choosing the right plant part at the right time of year and preparing it well makes a huge difference. 

People have been eating dock for a very long time. The Tollund man, 4th century BCE, Denmark, whose preserved body was found in a peat bog, had eaten a gruel that included dock seeds as his last meal. (Tollund mangruel). Dock seeds are easily collected, edible and nutritious, but hardly anyone likes the flavor. While dock seeds may never catch on, seeds of its relative buckwheat, Fagopyrum esculentum, are an important food. Buckwheat is not a wheat at all, but a plant very like dock from which we make both porridge and flour. 

                      curly dock, Rumex crispus

Curly dock has a long history as food and medicine. It is fair to call it a weed when it grows in the flowerbed with the zinnias or in a cornfield. But beyond that, it is a wild plant from Eurasia potentially useful to people all over the world.

Plant Story--Lily-of-the-Valley, Traditional Garden Plant

lilies of the valley Convallaria majalis

Lily-of-the-valley is a spring garden flower that I think of as "traditional", growing in long-established gardens of the eastern U.S.

 In Girl Scouts I sang
"White coral bells, upon a slender stalk
Lilies of the valley deck my garden walk.
Oh don't you wish, that you might hear them ring?
That will happen only when the fairies sing."

Added to their sweet fragrance, it made them plants I loved to encounter.

Plant Story -- Artemisia ludoviciana, silver wormwood, Louisiana sagewort

Pretty, eh?
Artemisia ludoviciana, Louisiana sagewort

Artemisia ludoviciana is a common grassland plant, native across the central and western United States, now found in most eastern states as well. It is in the sunflower family, Asteraceae, but it is wind-pollinated and so has tiny gray-green flowers, quite nondescript. It is part of the big group of native western North American plants often called sages because they smell like culinary sage, although they are not related to it (see previous blog post).

Dye Plants: "That's A Good Dye Plant"

On a plant walk recently, people noticed that I commented that various of the plants we saw were good dye plants. Sometimes I have little else to say about native plants. On the other hand, I enjoy dyeing with plants and so I always notice which plants are good dye plants.

Here are six plants I would say "and its a good dye plant" about:

My slides remind me of past adventures. Beginning in the late 1980s I collaborated with Guillermo Norrmann of the Universidad del Nordeste in Corrientes, Argentina. We were working on related grasses (Andropogon) from North and South America, and made good use of the similarities and differences. One consequence of this collaboration was that I visited northern Argentina several times.

I traveled halfway around the world, to tropical Asia, and the iconic plant I saw everywhere is one I associate with the American tropics, heliconia.

In Bali, the gardens there were glorious with heliconias.

But heliconias, also called crab's claws and even Japanese canna, are plants in the genus Heliconia, native to the New World tropics. I first met them in Costa Rica, and admired them where they grew in open spots in and along the lowland rainforest.

Tulips and the Tulip Bubble Part 2

This is part two of a pair of postsabout the Tulip Bubble, aka tulipomania, when in the 1630s in Holland the price of a tulip bulb inflated incredibly, and then suddenly dropped. My last post described Holland at that time. The merchant class had lots of money but because of sumptuary laws and Calvinist beliefs, spent it on houses and gardens not jewels and furs.Tulips had been introduced from Turkey after 1550. They were still uncommon and some highly desirable varieties were very rare indeed (link to previous post). The result was a bubble...

Tulips and the Tulip Bubble Part 1

Tulips are blooming.

red and white tulips

They're a riot of color that make people smile.

Yet economists make a Bad Example of tulips. Tulips created the earliest well-recorded bubble, defined by dictionary.com as "A period of wild speculation in which the price of a commodity or stock or an entire market is inflated far beyond its real value." Bubbles “burst” when a general awareness of the folly emerges and the price drops. 
 
The story gets a lot of attention because it seems so bizarre. How could someone spend thousands of dollars on a single tulip bulb? People did. At the peak of the tulip bubble, a bulb was traded for a house on the canal in Amsterdam, one of the most expensive locations in the world at the time. That's millions of dollars at today's prices.

Plant Story--the Merry Periwinkle, Vinca

Periwinkle is an early spring flower that doesn't get much notice. But it has long colorful history.

periwinkle, Vinca

The name periwinkle is an old English name for a group of plants native to Europe and the Middle East in the genus Vinca. The name periwinkle has been applied to a number of other plants, particularly related plants from the tropics with similarly-shaped flowers (Catharanthus). Periwinkle is also the name of a common seashell (Littorina littorea) and its relatives photos. I'll talk about the two species of perennial, creeping blue-flowered plants, Vinca major and Vinca minor, commonly planted all across the United States and much of Canada. You can find ornamental forms of periwinkle with variegated leaves and with flowers shading from deep blue-purple to white. Vinca minor, the common periwinkle is a little smaller but more winter-hardy than the greater periwinkle, V. major. They are members of the dogbane family Apocynaceae.

Plant Story--Stavesacre and Larkspurs in Europe

Delphinium, larkspur
Stavesacre. Would you think "larkspur"?

The larkspurs (Delphinium species) of North America are tall plants with curiously-shaped flowers in purple, blue or white. (Earlier blog, featuring American larkspurs link)

It was clear when researching American larkspurs that there were similar European plants because, well, the name larkspur is based on the flower looking like a lark's foot, but North America doesn't have a common bird we call a lark. The lark of England, more formally the Eurasian skylark Alauda arvensis, was a well-known and conspicuous bird of farmlands. Its numbers are drastically down recently and farmlands have retreated so perhaps it is not as well known as in the past link

Common Names -- Different Names in Different Places

I've been drawing attention to problems in looking up plants online by their common names. Here is one final issue with common names: they are often regional. That means you can find the same name on a different plant if you are in a different part of the United States. Or not find useful websites because on those websites they use a different common name.

goat's beard, Tragopogon
goatsbeard, Tragopogon
For example, looking at plant books from different regions, I find two goatsbeards, Aruncus dioicus (see photos I don't have one of my own) and Tragopogon spp. (above and photos). Aruncus grows across the eastern US., Canada and along the West Coast (USDA maps, description at Missouri Botanic Garden). Tragopogon grows there too, but eastern U.S. books it is called salsify or oyster plant. Aruncus is not found in the central U.S., and in some plant identification books from here, it is Tragopogon that is called goatsbeard. I believe the name goatsbeard for Tragopogon came with it from Europe (see Culpeper, Grieve). Aruncus is an American species, more recently named goatsbeard, for the way it looks. Currently, the USDA plants website has Tragopogon as goatsbeard and Aruncus as bride's feathers while the Flora of North America calls Aruncus goatsbeard and Tragopogon salsify. No knowing what you'll get if you ask for goatsbeard.

Bali Dye Garden -- Yellows and Reds

Red-dyed yarn and cloth
 in Threads of Life shop, Ubud, Bali
Why did the tropical Asian dye garden lack plants for yellow dyes and have so many marked as red dyes?

I thought I knew a lot about dyeing. I’ve grown most of the dye plants available commercially, for example madder, weld, and dyer's safflower, I've dyed with spinach, onion skins, red cabbage (link) and other fruits, vegetables and spices that have a reputations for producing dyes. I've thrown practically everything that grew in my garden, from marigolds to English ivy, into a dye pot and I've gathered wild plants from aspen and bindweed (link) to yarrow to make dyes.

recently-dyed silks
 Silk scarves I dyed in 2016
And yet, in Ubud, Bali, the dye garden of Threads of Life had plants I had only read about and ingredients for processes I'd never thought of trying. An afternoon was not enough to really understand what I saw.

Doubtless you are thinking: of course there would be new plants, the native plants of the central U.S. are very different from Bali, in tropical Asia. And that's is part of it.

Visiting Scotland--Beautiful Orkney

Orkney, Scotland

Sometimes the places I go are imbued with romance from my childhood. Ah, Orkney! In the King Arthur tales of my childhood, Sir Gareth of Orkney was my favorite. (Cliffnotes) Many places associated with King Arthur are in southern England, for example Cornwall, so I never grasped how far Gareth traveled to serve with King Arthur.

Carnivorous Plants, from Legos

Southeast Asia is famous for diverse and bizarre insectivorous plants.

For example these Nepenthes pitchers, seen in Seattle's Volunteer's Park Conservatory. About five inches long, the pitchers capture and digest insects to provide essential nutrients for the plant. Carnivorous plants are most diverse in low-nutrient ecosystems such as tropical bogs.

Nepenthes

So I was pleased to see Nepenthes pitchers at the Gardens by the Bay in Singapore.

Nepenthes

But wait! those aren't plants, those are built from legos!
