Cymbidium for Christmas

Today, a few days before Christmas, the weather turned very cold. The high today is expected to be -6F. Like other fool-hardy Minnesotans I ventured out to the greenhouse to fulfill my appointed duties. However, when I arrived there, only Curator J.. was in the building. He asked if I would stay and do a bit of sweeping, which I did for about two hours. There wasn’t a lot of debris under the benches, but every bench had a little bit. So the benches in all four collection rooms needed attention. I also swept the workroom.

I have to state the floors of the greenhouse look much tidier since J’s arrival, thanks in part to a leaf blower recently introduced to the greenhouse. He has made a significant effort to get pots up off of the floors onto low benches. The floors clearly are being washed more frequently compared to before his arrival. It is important for the greenhouse because it reduces the biomass on the floor for the proliferation of pests and fungus, which then spread to the plants in the collection, particularly if their pot is sitting directly on the floor.

Next week, I’ll contact A...to ensure there is enough for me to do on the 29th.

A plant that was particularly beautiful today was a cymbidium orchid in full bloom. The plant was approximately 4 feet in diameter and height. There were several flower spikes, each bearing half-dozen open blossoms, and as many buds. The blossoms were each 2 inches in size, with pale green petals bearing reddish-brown spots. The blossoms were not particularly showy, blending into the background foliage. But they were perfectly formed on closer inspection. Gorgeous!

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...
