Los Angeles farmer Tara Kolla shares her secrets to growing great blooms, using organic methods
Winning qualities: Their unparalleled fragrance. “The perfume industry has yet to duplicate it naturally,” says Kolla.
Flowers also come in lots of great colors, from pink, coral, red, and burgundy to deep lavender-blue.

Growing tips: Plant in rows running north to south, or near an east-facing wall; seedlings should be at least 6 inches apart.
