    Succeeding generations (1): Biophytum sensitivum

    The title of his article can be understood in two ways. If you have read my [About], you know that my goal in dealing with hermetospheres is to design miniature systems in which each plant reproduces over several generations. With this post, I begin a series of successful examples of second or third generation plants…

    Darwin and the mystery of the coiling direction

    When I acquired this plant as one of my first purchases to grow in a hermetosphere, it was labelled Marcgravia umbellata, but it might as well be Macgravia oligandra. Both plants originate from the caribbean islands and belong to the shingle-leaf climbers – root-climbing plants whose leaves are adpressed and often overlap (Zona 2020). As…

    The “little tree plant” (Biophytum sensitivum) is very popular among terrarium hobbyists. Its natural habitat are wet lands of tropical India and South-East Asia, where it grows in the shades of trees and shrubs, in grass lands at low and medium altitudes (Sakthivel and Guruvayoorappan 2012). It looks like a miniature palm tree, is perennial,…

    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,…
