Natural sweetener — leaves are 30–300× sweeter than sugar. Harvest before flowering for sweetest leaves. Frost-tender; grow as annual or overwinter indoors.
Campanula persicifolia
flowerThrives in the same full sun, moderate water conditions as Stevia

Tanacetum parthenium (L.) Sch.Bip.
herbA fellow Asteraceae — similar growing habits to Stevia
Stevia is usually grown from cuttings rather than seed. Take a healthy stem cutting, remove the lower leaves, and root it in moist, free-draining compost.
Water: Medium · Height: 60 cm · Soil: Well-draining, sandy, slightly acidic — avoid waterlogging
These three thrive alongside Stevia — and alongside each other.
