A real nerd here too! I like a lot the effect on the polystyrene, it really looks like some weathered terracota thing, a wonder when you think of polystyrene being one of the ugliest materials available!
Yeah. They are great containers size & drainage-wise but as you say, ugly. Putting them to work gives me heaps of potting space, which I really need. I reckon someone more artistic could do a lot better. The fruitbox was about my third go at it.
I do not think there would be a specific name and I wonder if it exists in any language though it is indeed the kind of experience everyone would experience one day would it be with dry wood, fake terracota or volcanic rocks (very surprising!)
Ian, I haven't seen you in years but I WANT THIS STUFF! All my ceramic pots have finally exploded leaving blue end terra cotta shards all over the patio--except for the ugly, tasteless styrofoam and plastic ones. They sell these huge styrofoam planters at the local big-box home store that has exactly the effect you two are talking about--you thing it's going to be sooo heavy and then you go to pick it up and it's like, ok, a whole handful of feathers, but not like a large heavy duty lurid black and blue stone planter. But because of the "lurid black and blue" part I have never been really tempted to purchase it. Now I know I can turn my hideously ugly styrofoam pots--I bought them because they were cheap, the lurid blue item I'm referring to is $50-100 USD!--into classic terra cotta. I'm ready. Thank you, Ian, wherever you are.
I wonder if Ian did not disappear during one of his experiences with fake terracota...I tried to get in touch but was sorry not to get through, I deserve him the luck to be one of DG writers as he is the one who introduced me!
