Stevia rebaudiana is a short-lived, herbaceous perennial with mid green foliage that has a serrated edge and bears small white flowers.
It prefers a warmer climate to thrive but will re-emerge in spring in cooler climates providing you mulch it well with straw over winter.
Harvest the leaves to make a sweet tasting infusion or use in cooking - good fresh or dried.
It also makes a perfect addition to mint tea which often needs some added sweetness.
