planted bottle

  1. Hyoscine

    What could I plant in a 20 litre bottle that would almost never need trimming?

    It was an impractical but just too alluring eBay thing; some lab glass that's basically the size and shape of an office water cooler bottle. It has a radius of about 30cm, rounds off at around 40-45cm high, and I can just get my hand and wrist through the neck. I'm hoping to scape and plant it...
