DON'T GET RUE!!!!! It burns like crazy

Mint is easy to grow, try stopping it    Rosemary is a must in any herb garden as is sage and thyme

Oops, killed the mint in our garden when we first grew it

Always good to remember about allergies when getting herbs especially for a sensory garden.

I wouldn't be without chives. 

Snip up a few leaves and put them in egg sandwiches for  the children to eat, add the flowers to salads and grow some more plants from the seeds which set easily after the flowers have faded

Bronze fennel grows quickly  (to about 6ft), it has lovely feathery foliage with a strong aniseed scent.
I personally haven't had much success with basil outdoors.
lemon verbena (best lemon scent) and lemon balm (which is hardier but can be invasive in open ground) are both worth growing and can be used to make a lovely sorbet.
