One of our three core roots is that we are Environmentally Conscious and for the past 30 years all the herbs grown at Jekka’s have been raised following sustainable, environmentally friendly and organic approaches resulting in a remarkable biodiversity at the herb farm.

Our herb seeds are also untreated and can be used to grow organic herb plants.

You can read more about our Sustainability Approach in one of Jekka's Blogs or in Jekka's Guide to Climate Change.
