Among the perennial herbs I have in the garden is thyme.
This bush was one of the first things I planted and has been there three years, although a month or two ago it was touch and go whether I got rid of it as it appeared to be getting past it’s use by date.
It had become very ‘sticky’ (all stems and no leaf), as it got older and it was increasingly hard to pick a nice bunch for chopping.
So, I took the shears to it very radically and it has bushed back beautifully. Maybe I’ll get another year or two out of it. It has occurred to me that thyme would be a very attractive small garden bush or pot specimen on a balcony. It hasn’t been affected by the frost, and it seems to be very drought tolerant, once it is established.
Garden Path Food 
I’ve got several thyme bushes out front as my raspberry to my HOA. I’m growing food out front; you just don’t know it. Mine are a few years old, and they are a bit sticky, but they’re also big and vibrant, and they continue to produce throughout the winter. I’m afraid to cut them back, but I know you’re right and that I should. They are doing a nice job as border plants though. 🙂
Yes, it would look good as a border plant, now I’ve realised it can be cut back. I love the thought of food as an ornamental in the garden.
Pruned citrus trees with a thyme border would look great.
Oh, they sure would. Perhaps I’ll move my dwarf potted lemon out front to increase my joy at flouting the rules. 🙂
