I thought that this was a new word before I googled it and found out that there was a US company of this name (to do with landscape architecture) and a mention in a UK business website that envisaged it, in the context of health and well-being, as a combination of volunteering and gardening. My concept for a U3A group was it not to be a talking shop, but around some sort of practical work within members gardens whereby people share their knowledge and help one another. The exact format (and title) would depend, as always, on someone coming forward as a group leader to foster interest and get it started. Over to you all.
