Perennial plants are a greener option than annual ones. The secret lies in their roots. Because perennials are planted once and can thrive for multiple growing seasons, they have deeper, more complex root systems than rip-and-replace annuals like marigolds and pansies or corn and tomatoes. These perennial plant root systems stabilize soil and prevent erosion. They aerate the soil and enhance its ability to hold water. They help sink atmospheric carbon multiple feet deep into the soil. And, when perennials are no longer productive in 5, 10 or 15 years, the roots decay and participate in the digestive microbial party alive and well in healthy soil. The belles of the edible perennial ball in Maine are asparagus, strawberries, blueberries and raspberries, rhubarb, and herbs like chives, parsley and thyme. Now, Maine farmers are experimenting with a perennial wheat known as Kernza that's an environmental booster. ~ Christine Burns Rudalevige
