We've all done that Shropshire lass - nurtured something that turned out to be a major weed.
Giood to see you back from your hols GG.
I remember when I first planted a "herb" garden in a chequer-board area with paving slabs and put my rotary clothes line in the middle. I did worry a bit about the bees around my ankles but it was the curry plant which grew vast and "scented" all the sheets that gave usd the biggest laugh.
I didn't replace it, or the rue which though beautiful threatened us with a nasty rash if we touched it on a sunny day.
The herb garden remains - filled with celandines at the moment, and low growing veronicas and sedums.....not quite the wafts of scent of crushed herbs that I intended, but quite pretty all the same.
