Arid vine maintenance

I returned to the Greenhouse after a 6-week break so that I could do some traveling. I'm grateful to be allowed the time away from the volunteer opportunity at the University's Botanical Greenhouse, which I so much enjoy. Today, I was assigned the task of maintaining the vining plants in the desert room, on the Collection side of the greenhouse.

The vining plants in this room are situated on one of the benches along an internal glass wall. The vines are attached to a number of wooden and metal trellises. Over the past year, the vines have grown and become a bit misshapen. Some of the stems are quite dead, or nearly so. My task was to cut down, prune, and re-string the vines to be ready for the coming growth season.

Here are a few examples:

Xerosicyos danguyi, silver dollar plant

Xerosicyos, or silver dollar plant, is in the cucumber family Cucubitaceae from Madagascar.


Fockea edulis

Fockea is a succulent shrub in the dogbane family Apocynaceae from Africa. It has the nickname 'water root.'

Bowiea, climbing onion

Bowiea volubilis, or climbing onion, is in the asparagus family, Asparagaceae. It is from the desert regions of east and southern Africa.


Adenia glauca

Adenia glauca is in the passionflower family, Passifloraceae, native to southern Africa.

Here is the finished product of my attempt to get the bench ready for the growing season:

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...

Rebuilding the support for vanilla vines

Raining in February   The morning began with a walk in the rain from my car to the Conservatory greenhouses - in the month of February. According to the calendar, we should be in the depths of winter. The precipitation today should be snow not rain. The storm system that we're experiencing is probably related to drenching rains moving inland from the west coast. I met Coordinator A... at the door of the Conservatory. His office desk faces one of the main doors to the building. He cannot escape observing everyone who enters...poor guy, it must be distracting for him. Anyway, as soon as I entered the building we started to discuss his plan for my activity of the morning. He offered me the project of rebuilding the support for vanilla vines which have been suffering from overexposure to sunlight and dry air. A bit of background The vanilla plant (Vanilla planifolia) is in the orchid family. It is native to Central America and Mexico. The seed pods were used by the Aztecs to flavor coc...
