I had a rather ramshackle old cane chair in the garden, more as an ornament than anything else. Those old Victorian reproduction chairs are lovely. However, when they have been exposed to the weather for long periods of time, they are weakened, as I found out when I randomly sat on it. The seat caved in and that was the end of that.
Not worth repairing, I was loath to throw it out (recognise a pattern?) so I made it into a garden in a seat. As the plants grow, it should look quite nice. If not, no harm done, as it cost nothing to experiment.

Liking all the whimsical items in your garden…
Thank you so much. A garden can be very much an extension and expression of your personality.
You certainly won’t be sitting on it now!
Yes, I thought plants would deter people from being tempted to do so.
