Fennel
Thanks all - I didn't really expect the basil to survive as I know it likes a warmer climate. But was surprised to lose the mint, which I don't think is a biennial?
I would love a rosemary bush but didn't plant that because I thought it needs a warm dry climate. And a certain type of soil.
The mint may well come up again next year. Mine looks a bit sad now.
Our lavender is doing well; we have very poor soil and the bees are enjoying it at the moment. The rosemary looks ok, rescued from Tesco a couple of years ago and the oregano is invasive as Esspee says. It is growing in the lawn, the rose bed, the other herb pots. Everywhere!
Rosemary thrives in a strong woman's garden. Apparently.
