    Acclimation (1): Ficus punctata

    Closed glass containers inevitably create extreme conditions for plant growth. This is especially the case for relative humidity, which can be assumed to be close to 100% at all times. Most tropical plants can deal with this, and hardly ever I could observe obvious changes from “normal” greenhouse conditions, where my plants usually come from,…

  • Neoregelia

    Neoregelia

    Bromeliads, the Bromeliaceae family, are among the most fascinating plants of the neotropical fauna. Most of them grow too large for a 5l hermetosphere. A few however do not only fit in size but also seem to find favorable conditions for living in hermetospheres. Initially, the Bromeliaceae family was divided into three subfamilies based on…

    Actiniopteris radiata

    One of my two jars inspired by the flora of Myanmar is currently able to tell more than one story. The fern called Peacock’s tail, Actiniopteris radiata, was meant to be the main protagonist when I started the jar in mid August 2021. Initially, the plant seemed to be comfortable and produced new fronds. After…

  • Bladderworts

    Bladderworts

    Bladderworts, genus Utricularia, seemed attractive to me for use in hermetospheres for several reasons. First, they usually live in and are adapted for wet or moist habitats. Second, a lot of species are native to tropical regions with little seasonal differences. Then, they are highly fascinating organisms, able to source nutrients from tiny animals they…

  • Barbosella cogniauxiana

    Barbosella cogniauxiana

    I currently run two jars representing Brazil Southeast, both etablished in May 2021. They both contain Barbosella cogniauxiana in different combinations. Under my standard conditions, the plant does very well so far. At the end of March 2022 it showed its extraordinary blooms for the first time. The specimen that served for the first scientific description…
