I want one! Just saw this in the Observer Magazine during my busy Sunday! I did water the garden, greenhouse and house plants between 5.15 and 6.30 this morning!.
Obviously it needs something like a conservatory or a wall with plenty of light. But how good would a wall be with 20 to 30 herbs and flowers giving both a vibrant vista and a fragrant scent. If I get rid of the radiator in the conservatory and replace with an electric storage heater I would have a wall that at the moment has a rather brilliant Ceropegia woodii. Maybe I could move the furniture a bit and plan properly for once. But already thinking of Corsican mint, chocolate mint, creeping thyme, greek basil, parsley.
