It seems I have got to that awkward age when I am simultaneously old enough to recoil from the new vocabulary of hipster-speak, yet still young enough to know that within a week or so I will find myself using it. The whole raft of new, often colourful gardening terminology that has accompanied the sudden influx of younger and more diverse voices into horticultural media, largely thanks to platforms such as Instagram, fascinates me. My favourite term is one I learned only yesterday from my suitably bearded and tattooed Instagram buddy @botanicalotter: plant-flexing.
