Gardener’s may say rosemary and thyme have similar growing needs, being drought tolerant and sun loving. Requiring adequate drainage but little else from the soil. Chefs will have an understanding of he depth of flavor from rosemary and the pine notes from both. The subtle citrus from lemon thyme.
For anyone who loves a curry it is great to be able to grow your own ingredients, even if you live in the UK and colder climates!
