Hanging a wall of bromeliads

I appreciate so much the Greenhouse staff for their ability to organize a group of student workers and volunteers - as I am. For example, when I arrived today there was a white board listing duties waiting to be performed. There is no need to stand around wondering what to do. Today my task was clearly outlined on the board: hang bromeliads.

Neoregalia hybrids (in the family of bromeliads)

My tasks listed in blue ink

Empty trellis, waiting to be filled with bromeliads

Located in the cool temperate 'cloud forest' room is a collection of bromeliads plants with the genus name of Neoregelia. They had been growing on the flat surface on one of the benches - as on a table top - occupying 50 square feet of bench space. That is a lot of bench space to devote to one plant genus. The proposed solution was to move the plants from a flat surface to hanging on a trellis in the same room.

My task began with moving plants to gain access the trellises. I then transferred clusters of bromeliads, a few at a time, to the trellis. I used zip ties to secure the aerial roots of the bromeliads to the metal trellis. I was able to hang only one-half of the collection because I ran out of time, and there weren't enough zip ties. More zip ties would have to be ordered to complete the project.

I experimented with one cluster of plants: I found a plastic mesh flat into which I cut a piece of coconut coir matt and fitted the matt to the bottom of the flat. Then I placed a cluster of the plants into the flat resting their aerial roots against the matt. I attached the roots to the plastic mesh by pushing the zip ties through the matt. Then I attached the flat vertically onto the trellis. The idea for the design was to allow water to soak into the matt and provide moisture for the plant, and an organic surface for the roots to grow against.

Ultimately we decided the experiment was over-engineered. The aerial roots would probably survive just fine on the trellis without the coconut coir matting. Most of the plants were secured to the trellis, hanging by their aerial roots, using zip ties only. I tried to angle the plants pointing up to help them retain water in their leaves when they get sprayed - which is daily.

Green bromeliads having been moved on to the trellis, red bromeliads are waiting to be hung.

Newly hung bromeliads

Bromeliads are a large family of plants which originated in tropical central America. There are 80 genera in the family, of which Neoregelia on only one. Other genera include those for epiphytic Tillandsia (air-plants) such as Spanish moss, and terrestrial plants such as pineapples which grow on the ground. Most are epiphytic, growing in the branches of trees, as does Neoregelia. There are thousands of hybrid species of a variety of patterns and colors.

Next week I'll be able to complete the tasks, if they haven't already been hung to make room on the benches where they had been growing.

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...
