A Quest for Sweetness

Looking for something sweeter than sweet?
Look no further! Extract from the Stevia plant, also known as Sweetleaf and Paraguayan sweet herb, is said to be as much as 300 times sweeter than sugar. Stevia rebaudiana, named after the Paraguayan chemist Rebaudi who first extracted the component stevioside, is one of 300 species from the Asteraceae family which includes sunflowers and chrysanthemums. From that family, Stevia is the only plant with such sweetness. Fresh Stevia leaves have a slight licorice flavor, sweeter than sugar. All natural and calorie free, Stevia does not appear to raise blood glucose levels, making it a plus for dieters and diabetics. Though it can not be used as a replacement for sugar in baked goods, it can be used to sweeten dairy products, puddings, sauces, salads and custards.
While it does not like cooler temperatures, in zone 7 you can grow it as an annual or in a pot which you could move indoors during colder weather. In the garden it grows 18 to 30 inches tall with gray-green oval leaves and sometimes white flowers. It prefers plenty of sunshine and a sandy or loamy soil (much like the Strange’s soil), kept moist but not wet. To avoid over watering, add a layer of compost or mulch to protect the shallow root zone from being exposed to too much water. If you are going to plant Stevia in a container make sure it is at least 10-12 inches in diameter. Fill the container with a lightweight growing mix and add a little mulch on the top. Stevia prefers fertilizers with lower nitrogen content. Most organic fertilizers would be ideal since they release nitrogen slowly.

To make sure you have the sweetest of sweet plants, harvesting should be done as late as possible. Shorter days and cool temperatures intensify the sweetness of the plant. The easiest way to harvest is to cut the branches off with pruning shears before stripping the leaves. Once all of your leaves are harvested you will need to dry them. Crushing dried leaves is the final stop in your quest to sweetness!
