Stevia rebaudiana

Stevia (Stevia rebaudiana) is commonly known as the sugar plant as its leaves have a strong sweetness, much higher than sugar. This herbaceous plant, native to South America, can be grown in pots or in the ground in regions with mild winters. The leaves of this natural sweetener can be used as a sugar substitute, with the advantage of providing no calories. Planting is done in spring.

Originating from South America, specifically from Paraguay, Stevia requires moderate humidity and warmth to grow. It is an herbaceous plant with a branched main stem and lanceolate and toothed leaves. It may produce small white flowers at the end of summer, but it is recommended to remove the flowers as soon as they appear in order not to weaken the plant. Stevia, which will reach a height of 60 cm (24in), can be placed in the vegetable garden or among a collection of herbs. It is not very hardy and can be grown in pots or in the ground in regions with very mild winters.

Stevia is grown for its leaves, which have a much higher sweetness than sugar. The leaves can be consumed raw, fresh, or dried, as a substitute for sugar in desserts (yogurts, fruit salads...) or in coffee. The two main compounds responsible for this sweet taste are stevioside and rebaudioside A. This natural sweetener has the advantage of providing no calories.

Harvesting: The leaves are picked as needed until the first frost. They are richest in steviosides at the end of summer.

Storage: The leaves can be consumed fresh or dried. Dry them in the shade, grind them into powder, and store them in airtight jars.

Gardener's tip: To keep the plants fresh in summer and protect them from the cold in winter, we recommend mulching the soil with thin successive layers of grass clippings, if possible mixed with dead leaves. This protection, which keeps the soil moist, also reduces weed growth.
