Heirloom herbs have much more flavor and scent than the hybrids of today. Heirlooms have been selected for flavor and performance over long periods of time, whereas hybrids are developed to meet market demands, and thus their scent and flavor suffers.
Heirlooms are living treasures passed from one generation down to another. Our inheritance is their flavor and beauty from the past for the future. Heirloom seeds are excellent travelers, as evidenced by the age of many varieties; some are several hundreds to several thousands of years old, and have traveled across several continents.
