Stevia is a genus in the sunflower family with about 240 known species. Sweetleaf is Stevia rebaudiana, which is native to South America. The greatest challenge with Stevia is germination. How to Grow Stevia from seeds ? Sweetleaf is famously difficult crop from seed. Once plants are established, they will grow well in hot weather, and are good candidates for summer containers.

Sow seeds on the surface of damp, sterile seed mix, and use bottom heat. Warmth and bright light are necessary for germination. Be advised that germination is challenging. The germination rate shown on our packaging reflects laboratory conditions. Without the use of bottom heat, few or none of the seeds will germinate. We highly recommend using a heat mat.
