Chinese Landscape Painters Painted What They Saw, repost

Repost from 2013

Huang Shan, Yellow Mountain, China

Books on art history tell me that landscape painting as a distinctive style first appeared in Europe in the 1500's. The Chinese have a much longer history of painting landscapes. Several landscape paintings from the 11th century survive and literary sources refer to earlier works. Here are links to two 11th century examples: Guo Xi Early Spring (1072) and Fan Kuan (10th-early 11th C), Travelers Among Mountains and Streams (scroll down).

Chinese  shanshui landscape painting

The landscape paintings of China look exotic. They are executed in ink with a brush and are often monochromatic. More familiar American and European landscapes are done in bright oil paint. (links to American landscape painters, and English landscape painters, Constable, for example).

The shapes of the rocks, mountains and trees in traditional Chinese landscape painting seem odd to an American eye. Clouds or fog fill parts of the pictures, adding to the dream-like quality.

When you look at Chinese landscape paintings with an eye used to seeing North American landscapes, it is easy to react in disbelief--"oh really?" The landscapes look imaginary.

What a trip to China shows you is that Chinese artists painted what they saw.

Huang Shan, Yellow Mountain (top of page and above) is an important Chinese destination but not a major stop for international tourists. It is dramatically craggy and can be very foggy.

The places in my photographs other than Yellow Mountain -- the rice terraces of Longsheng, the Li River between Guilin and Yangshuo, and the city of Hangzhou -- are common destinations in tours to China. My exotic-looking pictures did not require going to remote Chinese locations but were taken in accessible, commonly-visited places in China.

Guilin, China

Chinese landscape painting is exotic to the western eye but the artists painted what they saw. The landscapes are unlike western landscapes.

To someone who grew up in Guilin, China, North American or European landscapes must look exotic.

Whatever your ordinary is, go see exotic landscapes!

Small Soapweed, Yucca glauca, repost

Here is another repost from 2013: Small Soapweed, Yucca glauca

Yucca glauca in flower

     Standing like candles in the prairie, flowering soapweed yuccas make a handsome display.

A young Yucca glauca.
You could cover all but the
outer tips of the leaves by
setting down a pop can. 

     Soapweed yucca, Yucca glauca  (asparagus family, Asparagaceae) is found from Canada to Mexico across the central U.S., in areas that before settlement were grasslands.

   Like other yuccas, Y. glauca has a rosette of leaves and can live many years. The plants start as tiny rosettes of short thin leaves and as the plant gets older, the leaves get more numerous and longer.

  The leaves are tough and fibrous, with a sharp point at the tip. Cattle generally avoid eating the leaves. Biologists generally avoid walking where the leaves will stab their legs. The evening volleyball game at Cedar Point Biological Station featured the phrase "stucka by a yucca" for players who ran heedlessly after a stray ball into the plants surrounding the improvised volleyball court.



   Fibrous leaves with stiff points on the end can be useful. Plains tribes and early settlers carefully peeled back the tip, keeping a long fiber attached, and had an instant needle and thread. The fiber is pretty tough and makes an effective little thread.

Yucca glauca flowers

   Although yucca leaves are strong and well-defended, Yucca glauca flowers are totally edible. Soft, pleasant and appealing, after washing to remove bugs, they can be eaten raw or cooked, boiled or fried. The deer, elk and pronghorn know that and frequently strip all the flowers off a flower stalk.

   Bumping a yucca in flower usually results in several small white moths flying away. Yucca glauca is like other yuccas in being pollinated by a moth who lays her eggs on the developing seeds. She is both a pollinator and a seed-eater. The relationship is long-standing so that the flowers and seeds of yuccas are modified to accomodate this moth. If she doesn't carry pollen between flowers, no seeds are produced because while plant requires pollen from another plant in order to develop seeds, it has no mechanism for getting that pollen unless a yucca moth specifically carries pollen between plants.  It has no rewards or attractions for other insects.

    The seeds develop in three neat columns. Generally a moth larva eats its way down one column, growing bigger all the time. The female moth may lay eggs on two of the columns of seeds, but never on all three. Obviously, there can be problems if two females target the same flower, but generally they leave scent marks to warn later arrivals to go elsewhere. Since this relationship depends on the plant getting some seeds while feeding the moth, avoidance mechanisms usually work and each yucca flower both feeds one or two moth larvae and develops a column of seeds.

Yucca glauca roots
Compare the drying leaves, 
top left, to the size of the roots!

   The name soapweed is applied to Yucca glauca because there are saponins, soapy compounds, in the roots. Native Americans and settlers used yucca roots as a source of soap. I have tried it. It doesn't make much lather but it does remove dirt and grease. Making soap from ashes and lye is a lot more work than gathering yucca roots.

   Like most plants of the prairie, soapweed yuccas are deeply rooted. The prairie is a grassland with relatively short plants in part because it is too dry for bigger plants to survive. One mechanism for surviving the periodic droughts of the prairies is having deep or widespread roots that seek water in a large volume of soil. Digging up plants is hard work but sometimes I spotted them at the bottom of eroding banks and road cuts. To the left a big old yucca, showing the massive roots that grow below a modest-sized plant.

dying yucca; to the right there's 
a pile of litter from
a yucca that died previously. 

     One last use for yucca that I have never tried: it is supposed to be your ready-made fire site. A dead plant, slowly rotting, has a lot of small fibers in the center which reportedly serve as tinder, and the sharp points of a group of leaves can be rubbed against a hard surface to create sparks. The one in the picture is slightly too green, I suspect, but at the lower right is a pile of pretty well decomposed yucca leaves, suitable for building a fire.

     Very few people are skilled enough to make fire with an awl these days, and generally prairies are too dry to light fires safely. But if you imagine yourself lost from the wagon train in, say October 1850, having chased the prairie chickens without paying  attention to landmarks, a yucca as a source of fuel to start a fire might be very welcome.  As I play out this scene in my head, I look around and think, "but, intrepid pioneer, you will also need to find something else to burn or your fire won't last an hour."

 Prairies are difficult in many ways, not the least the lack of firewood. Got  buffalo chips?

Why do Botanists Always Tell You the Plant Family? repost

Repost from 2013: Why Botanists Always Tell You the Plant Family

People writing about plants are forever sticking the plant family into the discussion.

Not Always Just Plain Vanilla, repost

I am taking a break this month, reposting previously published blogs. This one is from February 2013, the first month of this blog. And, I could not resist som editing, especially giving credit to Edmond Albius for discovering vanilla needed to be cross-pollinated. 

     Good vanilla is one of my favorite flavors, and the idea of "plain vanilla," vanilla as the no-flavor flavor, has always been somehow annoying.  And it wasn't always the case.

The vanilla orchid is the plant in the middle, 
hanging down over the tree branch. (In the 
Conservatory at the Smithsonian in 
Washington D.C.)

   Vanilla is native to the Americas and although probably in use for millennia there, it only reached Europe after 1492. At that time it was a rare and highly desirable flavor.


   Vanilla comes from “beans,” long thin bean-like pods, but vanilla is not at all a bean (legume, plant family Fabaceae), but an orchid (plant family Orchidaceae). In fact, it is the only orchid used as a food, or used by commerce in any other way than as ornamentals (flowers) even though there are more species of orchids than species in any other plant family, legumes and grasses included.  

Butterfly Pollination, A Quick Overview

Long ago, when plants began exploiting animals to carry pollen between flowers, they encountered butterflies. Butterfly adults fed mainly on sugar water (nectar). Flowers adapted to this by offering little cups of nectar, positioned so that a feeding butterfly would get pollen on itself--on the proboscis or face or wings, depending on the flower--which then pollinated the next flower of the same species when the butterfly moved to find more nectar there. I said "exploit" but for most flowers and butterflies it is a reasonable trade, pollen movement for food, making butterflies a major group of pollinators.

We Called it Ditch Weed and Left it Alone (Cannabis sativa)

The New York Times (11/20/24) reported funding of research on whether cannabis extracts can effectively treat post-traumatic stress disorder (PTSD) and commented that this is a first because as a Schedule 1 Narcotic, permission to study cannabis has been difficult to impossible. That set off a lot of memories for me.

Teasel, Dipsacus fullonum, Once an Important Tool

Teasels, Dipsacus fullonum and Dipsacus sativus,  in the teasel family, Dipsacaceae, for centuries were essential to the clothing industry. Today, in North America, they are noxious weeds.

Quick Overview of Bee Pollination

Bees are numerous and are good pollinators, so many plant species have flowers tailored to bees.

Plant Story--Artichoke, Cynara cardunculus, Edible Thistle

You do know that the artichoke is the immature flower head of a thistle, don't you? It is a strange vegetable, with layers of leaves you tear off to eat a bit of "meat" at the base, but that doesn't make most people think of thistles. Nevertheless, the artichoke, Cynara cardunculus, sunflower family Asteraceae, is the cultivated version of a big thistle from around the Mediterranean, the wild ones called cardoons or artichoke thistles.

Photo Story--Beautiful, Stark Salta, Argentina

Just as in North America, the prevailing winds bring moisture from the Pacific that drops on the mountains, making a dry zone at their base in eastern Oregon and Washington and on the Colorado Front Range, so in South America, the winds from the Pacific leave their water on the west side of the Andes and at the base of the mountains, on the east, it is very dry. This effect is the most dramatic as you approach the tropics, in North America in Arizona and northern Mexico, in South America in northwestern Argentina's Jujuy and Salta Provinces.

Plant Story--Colorful Common Tansy, Tanacetum vulgare

Tansy is a small plant with bright yellow flowers and a spicy smell (scientific name, Tanacetum vulgare sunflower family, Asteraceae). It is native to western Asia but long ago became an herb and spice that was grown throughout Europe and then transported by Europeans all over the world. Today we know it more as a garden flower or roadside weed than as a flavoring or medicine, but it is all of those.

Plants and Pollinators

 One of the ideas that attracted me to ecology as a student was pollination. In particular, the match between flowers and their visitors. Bees like open flowers like echinacea and bees can enter closed flowers like peas, but some flowers are too long and narrow for them to reach the nectar. This results in patterns in nature, plants that are mainly bee-pollinated, for example, and plants that are not pollinated by bees. And those bee-flowers share characteristics, so that you can recognize them, just as bees do.

                                The pollen and stigma are hidden inside the lower lips of the flower,

                                   they bump into the bee's abdomen as it feeds, transferring pollen.

Plant Story--Handsome Ten-Petal Blazingstar, Mentzelia decapetala

The blazingstars, genus Mentzelia, are an American group, but especially western North American. Some species are found in the Caribbean, Central, and South America but 85 of the approximately 95 species are North American. If you live in the eastern half of the United States, you can be forgiven for never having heard of this group, because only three species have ranges east of the Mississippi. (Those are a Florida endemic and two found east to Illinois). Colorado has 25 species, almost all in the western half of the state, west of the Rocky Mountains; only four species grow on the eastern plains. They are in the small plant family Loasaceae, the blazingstar family.

Plant Story--Hedge False Bindweed, Calystegia sepium

In the regions where I have lived in the last 50 years, Colorado, Nebraska, I knew only two bindweeds, the very common field bindweed, Convolvulus arvensis (blog), and the much rarer, hedge bindweed, perhaps better called hege false bindweed Calystegia sepium, both with white tubular flowers open in the mornings. Hedge false bindweed is much bigger--and so quite beautiful--and although I saw it climbing through roadside shrubs, it didn't seem particularly weedy.

Reading about hedge false bindweed, though, I find it is immensely complicated.

Travel Story--The Burren, Limestone Outcrops in Ireland

In western Ireland, there is a region of limestone outcrops, called the Burren. Great expanses of limestone rock lie at the surface. You can see them as the hills in the distance in the photo. Plants grow in crevasses, but nothing grows on rock, so it has never been cropland.

Plant Story--The Beautiful Roselle, Hibiscus sabdariffa

The roselle is a small hibiscus, Hibiscus sabdariffa, (cotton family, Malvaceae) that is grown as food, but pretty enough to be grown as an ornamental. Also known as Jamaican sorrel, roselle is a tropical perennial which can be grown outside the tropics as an annual. The stems are red, the leaves green, the veins in the leaf red. The flowers are white or yellow with dark centers. Around each flower are a series of fleshy red sepals and another circle of red bracts that look very similar. The sepals are gathered and eaten, sometimes under the name "hibiscus flowers."

Plant Story--Meadowsweet, Queen-of-the-Meadow, Filipendula ulmaria

Meadowsweet, Filipendula ulmaria, in the rose family, Rosaceae, is a lovely and conspicuous European wildflower, now naturalized in the eastern United States (known there as "queen-of-the-meadow").

Western Nebraskan Plants Easily Seen At Cedar Point Biological Station

Recently at the University of Nebraska's Biological Station, Cedar Point, at the Station's 50th anniversary, I failed to take very many photos of buildings and people. Here are a few of the photos of plants I took, instead.

buffalo burr, Solanum rostratum

For example, buffalo burr (Solanum rostratum, tomato family Solanaceae). Native to North America, it gets its name from its presence in areas denuded of other plants by bison, and since then, by cattle.This big-flowered plant has impressive spines (look next to uppermost flower in the photo above). The burs will stick to animal hair, dispersing it.  It is also rich in alkaloids that deter insects. It is one of the American plants that has gone around the world as a weed. Okay, it is hated around the world, but it is nevertheless a plant success story. Look and don't touch. 

Cedar Point Biological Station's 50th Anniversary (Ogallala, Nebraska)

The University of Nebraska's Cedar Point Biological Station in Ogallala, Nebraska, is celebrating its 50th year. Opened in 1975, using the facilities of a former Girl Scout camp, Cedar Point has each year since then hosted summer biology courses, geology courses, art courses, and experiential learning by children of many ages. Researchers staying there have studied everything from soil mycorrhizae and beetle intestinal parasites to prairie grass genetics and barn swallow social behavior.

Roadside Wildflowers of Southern Ireland

I took a tour of southern Ireland in July (photo tour link). For me, though, every tour is a plant tour. Here are some of the plants I saw along paths and roads:

blue tufted vetches (Vicia cracca, called bird vetch in the U.S.)
and unknown white flower (fools parsley, Aethusa cynapium?)

Plant Story: Zinnias, American Wildflowers

Zinnias are common and familiar garden flowers, in the genus Zinnia, sunflower family, Asteraceae. They come at the end of the alphabet in lists of garden flowers and indexes. Neither edible nor much of a medicinal, zinnias get little comment beyond "easy to grow."

The more I read about zinnias, the clearer it was they are under-valued.

The hill ahead was burned. Look at those sad dead trees!

So you take the fork in the trail going away from them.
