My first day as a greenhouse volunteer

I began volunteering at the Conservatory and Biological Collection greenhouse, in the University of Minnesota’s College of Biological Sciences. In early 2021 I contacted the director of the greenhouse, by email, asking to be added to their list of volunteers. She replied that due to the pandemic the greenhouse was closed in the first half of 2021, but reopened in July of 2021.

I had initially searched the internet for volunteer opportunities in my neighborhood. Given we were still in the throws of the covid pandemic, and that there are vulnerable members of my house, it was necessary to limit exposure for lots of unmasked people. I searched the internet for volunteer opportunities in local greenhouses. Miraculously, the very first search result described and opportunity at our local university greenhouse, not more than a few miles from my apartment.

On my first day, I was assigned to watered plants in two of the four collection rooms, C2 and C3. A... briefly described the goal and technique for watering each pot. Eventually, I was handed the greenhouse manual which described the process in detail. Perhaps I didn't do such a great job with watering pots since I have only rarely been assigned to watering pots a few times since then.

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...

Bog Monsters

As a layman of botany the idea of carnivorous plants has perplexed me. The capturing and eating of other creatures seems like it ought to be limited to animals, since animals are mobile and plants are not. Almost all plants survive and thrive in the world through photosynthesis. They do not need to feed on animals to survive. But, what about the group of plants that are carnivorous? As stationary plants, why and how do they eat critters? This topic was stimulated by my assignment today at the Conservatory Greenhouse of the University of Minnesota. My task was to clean several large tanks of water filled with aquatic plants. While cleaning the tanks I realized many of the plants were classified as carnivorous . What is it about the aquatic environment that causes plants to eat - in effect - other creatures? The short answer is carnivorous plants evolved in nutrient-poor settings such as pond water which is naturally low in the amount of nitrogen needed to synthesize proteins. To compens...

Autumn Inside the Greenhouse

I felt the firm grip of fall as I walked the half-mile from the parking lot to the Conservatory Greenhouse at the University of Minnesota, where I volunteer. The temperature outside was in the 30s, and the wind whipped at my face. Yesterday there had been snow flurries.  In stark contrast to the outside world, the greenhouse climate was quite different. Part of the greenhouse is maintained at near-tropical temperatures. But other sections of the greenhouse are kept significantly cooler to support plants that have evolved in seasonal climates. Although indoors, autumn has arrived here too. The sunlight dims, and the nights grow long. Inside these cool greenhouse rooms the plants shed their leaves and virtually cease growth for the winter months, just as they would outdoors.  Part of my assignment for today included the pruning of yellowing and brown leaves. Removing the dead foliage from the plants and the floors helps to reduce the overall risk of mold and other pests affectin...
