About Stevia
Stevia is the natural zero-calorie sweetener — the leaves are 200-300 times sweeter than sugar. Easy to grow as a container plant and overwinter indoors in cold climates.
Start from transplants (seeds have low germination). Grow in a pot and overwinter indoors in frost-prone zones. Harvest leaves before the plant flowers — sweetness peaks pre-flower. Dry leaves and crush for sweetener.
Gardening in Idaho
Idaho has a semi-arid continental climate. Southern valleys are Zone 6-7 with hot dry summers; northern regions and mountains are colder. Excellent for root vegetables and cool crops.
