English lavender has the fullest, sweetest flavor, with lemon and citrus notes that add verve to lemony drinks (especially limoncello) and sparkling wine when used primarily as a syrup. Garnish a champagne flute with a single flowering stem and wait for the wows to follow.
Grow it: Lavender does well in hot temps and ceramic pots, which breathe. It does need good drainage, though. Cover the bottom of your pot with gravel, fill with a good potting mix, and place the container in full sun, or someplace that gets at least 3 to 4 hours of sunlight a day.
