Repotting succulents from Africa

Both Director A... and B... were back in the greenhouse this week, having been away last week.

My first task was to pot a couple of cactus-like plants in the aster family: Kleinia pendula (inchworm plant); and K stapeliiformis (pickle plant). Both are finger-like succulents with spines like a cactus or euphorbia. They originate from Africa. Each variety had approx 8 10-inch stems which (previously calloused overnight) I inserted into an arid mix, all in one terra cotta pot.  The plants were donated by Madison (I assume UW at Madison WI). I was asked to bury a label deep in the base of each pot with the plant’s name, date, and my initials.

I also repotted a couple of small agave-like plants in the asparagus family, which originate from S. America: Furcraea guerrerensis. They were each planted into 6-inch terracotta pots with an arid mix. The plants were donated by Madison (I assume UW at Madison WI). I was asked to bury a label deep in the base of each pot with the plant’s name, date, and my initials.

I noticed the bin of arid mix was pretty low, almost empty. I refilled the arid mix bin, approximately ⅔ full. I rolled the bin into the well-ventilated hall next to the store room. I mixed the soil with a spade in that hallway because the charcoal is so dusty when agitated. The charcoal dust is overwhelming if mixed in the small storeroom.

During the weekly morning meeting I grabbed a pail and sheers, visiting the display rooms to trim and pick up dead leaves.

Finally, for the day Director A... asked me to shield the vanilla vines from the spray of the nearby mist tent. The vanilla pots were too soggy from the excess spray. Rather than shield the vines using a fabric barrier, we decided to put a shut-off valve on the spray head nearest the vanilla vines (see photo). A showed me to the boxes containing spare parts, located in the store room. The tubing parts are similar to those that I use at home.

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...
