Desert orchid and other diverse desert plants

Al... was the only person in the greenhouse when I arrived there. My first task was to help her distribute plants back to their home spots, having been lent out to one of the classes, for demonstration purposes. I suspect the class demonstration focused on the different types of plant leaves. I learned how to use the computerized data library of plants at the greenhouse. The plant library is useful to look up the location of specific plants. Unfortunately, the database only lists the room in which the plant belongs. It does not indicate on which bench the plant is located. One has to search the room to find similar plants in order to find a specific plant.

I spent the next hour and a half in Display Room 3, the Mediterranean Scrubland. I spent the time picking up leaves and trimming dead branches. In particular, I focused on the eucalyptus varieties, which tend to drop many of their leaves onto the ground.

The final hour was spent in Display Room 4, Diverse Deserts. Again, I swept up small dead leaves from the bed, and trimmed dead branches (there were very few). I discovered a few useful techniques: first, I used a pointed metal trowel to guide the white plastic labels into the granite gravel. Without the metal blade of the trowel, it is nearly impossible to push the bendy plastic into the sharp-edged granite gravel. The second technique is to use a long handle broom (preferably an old one) to lightly sweep the small leaves from the surface of the granite gravel covering the beds. Using a light touch lifts the dry leaves, but the gravel largely stays in place on the bed.

One very cool plant I noticed as I was cleaning is an orchid which has become adapted to a desert environment (see photo). It is called Eulophia petersii, native to Kenya. The leaves most resemble aloe or sansevieria plants.

A Sensitive Plant and Common Weed

Mimosa pudica, also commonly called the sensitive plant was a popular houseplant when I was growing up in the 1970s. It was popular for its ability to quicky change shape by folding up its leaves to protect them from herbivore predators. At the slightest touch the plant is able to expell water from special cells in the leaves, changing the shape from frond-like to a stick-form. The plant creeps along the ground, never for than a foot or so in height. In tropical parts of the world this plant is considered and invasive weed. Today, as I was treating plants to remove pests I happened to touch the leaves of a Mimosa pudica , one with a pretty puff-like flower. Sure enough, the leaves all folded up to almost nothing. Mimosa pudica , the sensitive plant Other more routine chores during my four-hour shift at the U of M Conservatory included cleaning three plants of Hibiscus clayi, native to Hawaii. These three plants in particular have suffered repeated infestations with a variety of in...

A Thames River Walk Through Time: Repurposing Tow Paths

I love it when old technologies are repurposed to solve entirely different problems. A perfect example is the extensive system of canals and tow paths throughout England. Before the Industrial Revolution and the advent of railways, these canals were built to transport goods between cities and towns. Narrow boats pulled by horses or mules along tow paths were a common sight. Today, however, these tow paths have found a new purpose: recreational walking. They offer picturesque routes through the English countryside, allowing people to explore the beauty of the canals and rivers. The commerce that once flowed along these waterways may have shifted to railways, but the paths themselves continue to serve a valuable function. This year, I had the privilege of joining three other hikers on a journey along the River Thames tow path, from the city of Oxford to its source, a distance of about 50 miles. Farther upstream, the river gradually narrowed, eventually transforming into a swollen creek b...

Plantulary: Botanical Dance

The title of the dance performance was Plantulary. The theme, botanical. On a whim, my partner suggested we attend a performance of a new dance work by a small immersive arts collaborative, Aniccha Arts. Through the arc of a single year—from growth through to dormancy—the dancers describe the story of plant life using percussive dance rhythms, music, literary, and various vegetable props. For me, this dance performance was a challenge to appreciate; it was no Swan Lake. I didn’t fully understand the connection between many of the sound and dance elements. But, curiously, the memory of it has stuck with me for the past few days. To set the scene, the stage consisted of a simple dark room lit by spotlights and early evening sunlight coming in through large windows. Along the baseboard of the stage were narrow trays of green seedlings lit by fluorescent grow-lights, forming the outer limit of the performance space. To further imbue the stage with plant life, several moss balls (kokedama-l...
