'Stevia' is a plant in the Stevia genus with a scientific name of Stevia rebaudiana.

A tender perennial that is usually treated as an annual this plant has sweet tasting leaves that can be used in drinks or cooking. Sometimes marketed as a sugar substitute. Approximately 1 teaspoon of dried Stevia powder, or 3 tablespoons fresh4, equals one cup of sugar.2

Approved by the US FDA as a dietary supplement since 1994.1 Stevia is 30 times sweeter than sugar4 and extremely low in calories.

Crushing the dried leaves is the final step in releasing stevia’s sweetening power.

Liquid stevia extract can be made by adding a cup of warm water to 1/4 cup of fresh, finely-crushed stevia leaves (or 1 quart water to 1 tablespoon dried leaves2). This mixture should set for 24 hours and then be refrigerated.1 Use within a few days or freeze.2

Leaves appear approximately as a   Napier green

Stevia is a herb perennial, it will last at least up to several years in its native climate.

Paraguay is believed to be where Stevia originates from.

Stevia needs a moderate amount of maintenance, so some level of previous experience comes in handy when growing this plant. Ensure that you are aware of the soil, sun, ph and water requirements for this plant and keep an eye out for pests.

Enjoys a full sun / partial sun position in your garden and remember to water moderately. Zone 11 to 14 are typically the USDA Hardiness Zones that are appropriate for this plant (although this can vary based on your microclimate).

Growing Stevia from seed

Sow seed on surface of soil.

Transplanting Stevia

When plants are large enough to handle, transplant into 3" pots and keep indoors until nighttime temps are regularly above 50 degrees Fahrenheit.

Ensure that temperatures are mild (minimum night temperatures should be around -6°C / 21°F) and all chance of frost has passed before planting out, as Stevia is a tender plant.

Harvesting Stevia

Seed saving – Seeds can be harvested when seed heads are fluffy and light. Gather before they blow away.

Pick leave from the plant and wash. Use immediately in any of the ways mentioned below or dry for use later. When dried Stevia leaves should remain green.

Dried & powdered the leaves are used as a substitute for sugar. In theory one teaspoon of stevia or less is equivalent to about 1 cup sugar. Some people notice a slight after-taste, while others do not.2

A liquid sweetener is made by pouring 1 quart of boiling water over 1 tablespoon dried leaves and leaving to infuse. Refrigerate and use within a few days or freeze for later.2

To make a syrup, place 4 teaspoons dried powdered leaves in a saucepan with 2 cups water, simmer slowly for 10-15 minutes. Cool and refrigerate. A teaspoon of Vitamin C powder may be added to act as a preservative.2

An extract can be made by combining 1 cup vodka with 3/4 cup fresh stevia leaves in a jar. Shake every day for 2 weeks, then filter through a coffee filter. Add a drop to beverages.

An infusion of fresh or dried leaves can be drunk as a beverage, hot or cold, or added to other herbs as a sweetener.

If using fresh leaves to replace dried quantities listed above, multiply the amount 5 times.2

Approximately 6 large leaves chopped finely is a substitute for 1/2 cup of sugar for baking or in cooked recipes. 1 teaspoon of ground stevia is equal to 1 cup of sugar; 2 drops of liquid essence is equal to 1 teaspoon sugar.2
