So, what I called "dwarf Tradescantia zebrina" is called in fact "Tradescantia minina Callisia repens". Comes from Bolivia and is thus called also "Bolivian Chain plant", or "Bolivian Turtle vine".
It is a low maintenance, very hardy and easy to spread, perennial succulent.
Now, as for my cuttings, for which I have dedicated my kitchen windowsill, I have the Hedera helix ivy rooting already, the Aloe plants are also showing some chunky roots, the Tradescantia silamontana top cuttings, the Tradescantia Pallida and the Sedums. All the experiments with the more woody stems are failing at large, it seems only tender stemmed plants are propagated easily in water. Just a note for the future.
I haven't had the time to work on ageing the remaining terracotta pots. The ones I have already done, need some sanding also, to soften the harsher lines of the paint given.
Also a side note, never to buy these huge terracotta pots EVER AGAIN. Too heavy, too space consuming, albeit they are gorgeous lookin'. I want more plants and have to prioritize thinking of the available space that I can use.
On the end of the month I will purchase more succulents for my collection and also some small plants to use into filling the big, empty surface of the already "filled" pots, which, to speak the truth, look awful with those leggy chamaedoreas, or the Corn plants alone.
