Stevia leaves are known for their calorie-free super sweetness, and this polite, tender perennial is easy to grow. In our area, it dies back in winter but comes back in spring. It enjoys the same garden conditions as other herbs such as basil—good soil, good drainage, and moderate water. Try dropping 2 or 3 fresh bruised leaves into your favorite tea for a lovely fresh sweetness.
Classic pesto basil. Keep flowers pinched off to promote leafy growth.
