Completing the bromeliad project

I often feel guilty after my trips to the CBS (College of Biological Sciences) Conservatory at the University of Minnesota. They are supposed to be earnest volunteering events. But really, it feels like recess or playtime. The best part is that there is almost no stress: there are world class experts to consult if I have a questions, and the best part is I have no deadlines, peer reviews, compliance courses, diagnosis or billing codes to muddy the experience. I feel a bit sheepish for getting so much joy with almost none of the responsibility other than arriving on-time at 10:00 a.m. - a very civilized hour of the morning.

Today I learned so much. My task today was hanging bromeliad plants. This is a project I started last week but couldn't complete due to lack of time and materials. On the way, I passed these two interesting orchid plants. They were just sitting at my elbow as I worked to hang the bromeliads.

Bromeliads newly hung up on a metal trellises

Last week I hung the larger green variety of the Neoregelia hybrid bromeliads. This week I worked to get the smaller, dark red bromeliads up onto the trellises. Zip ties were used to fix the woody stems to the trellis. I tried to angle the cups of the plants upward to hold water. They get sprayed daily with a weak solution of fertilizer.

Newly freed-up space for other plants in the collection

By hanging the bromeliads on a trellises, rather than allowing them to spread on a horizontal bench surface, at least 50 square feet of precious greenhouse bench space has been freed. This allows space for expansion of other plants in the collection.

Finally, I know it is tacky to mention specific software apps, but I only mention it because it is new to me. The staff of the CBS use the app called Slack to communicate amongst themselves with issues related to the CBS conservatory maintenance. Today I was invited to join the Slack group in order to be up to speed with changes and ongoing issues in the Conservatory. The Slack app is new to me. It is a shared communication board for everyone to read, like an electronic whiteboard. It is an efficient way for the staff to communicate with everyone at the same time, better than having to send messages separately to everyone's text and email inboxes - and having to keep those lists up to date.

I celebrate learning this about cycad plants

I didn't know that the cardboard palm - Zamia furfuracea - is a cycad. It isn't a palm tree (don't judge me, I'm not a botanist). But it also doesn't look like the other more familiar types of cycads with their fluted upright palm-like fronds. I didn't know it is said to be the second most commonly cultivated cycad, after Cycas revoluta . I didn't know this plant is unrelated to the common ZZ plant - Zamioculcas zamifolia - although they have a similar appearance. Before today I didn't know any of these things, but now I am happy to have learned them. From the parking lot I walked to the U of M Conservatory greenhouse in near-zero F weather. Stepping into the tropical spaces was a joy of its own. But being able to learn new information and experience new procedures was a compounding factor. Joy squared. During my 3-hour volunteer shift, my initial task was to clean the parasite critters (mealybugs and scale) from the stems and leaves of the cycad, Zami...

Mobile indoor green wall

Finally, after three years... my plant vines have grown and spread to be green wall that I had hoped for. I'm not sure it would have taken as long if the plants were in a more humid, sunny climate, et cetera. But given our indoor Minnesota location - even with a southwest exposure - the vines have needed that amount of time to climb the six feet from the base to the top rungs of the metal grid supporting them. The result has been worth the effort. And to be honest, I didn't have to wait three years to begin enjoying the green wall. The vines were already attractive when only half way up the trellis. A metal grid is filled with mix of Epipremnum aureum cultivar "Marble Queen", Epipremnum aureum aka golden pothos, and Philodendron Brasil . Architecture of the green wall The initial intent of the project was to grow a green wall, in an apartment, that could be moved around to be able to clean underneath, and also to provide a mobile room divider for our open-plan loft....

Strung out in the greenhouse

The assignment for my four-hour volunteer shift at the University of Minnesota Conservatory greenhouse was clearly listed on a whiteboard, with my name attached. Since most of the tasks involved working with strings of overhead cables or air tubing, much of my shift was spent at the top of a ladder. Vining plants are limited to only a few of the many benches in the greenhouse. Steel cables are strung above the benches to support their growth. Because many plants grow in a small space, part of the challenge is to untangle and separate the vines so that they don't strangle each other. Not many of the vines are blooming at the moment, as it is winter. However, Thunbergia grandiflora is producing a few lovely blue flowers (its tendrils grow clockwise, hence the common name Bengal clockvine). It's a popular houseplant, but it has become an invasive weed in parts of the world, like Australia, especially around waterways. Thunbergia grandiflora; notice small brown scale insects sucki...
