Seeds of sweet breed hybrids germinate and grow well under cool conditions, says Mark Willis, vegetable seed manager for Harris Seeds in Rochester, New York.
Plants are easy to grow and they produce tall, sturdy stalks.
Yellow and white kernels are crisp and sweet. Unlike other extrasweet corn varieties, though, 'Sweet Symphony' doesn't fully develop its sweetness until kernels have reached maturity. At planting time, isolate 'Sweet Symphony' from supersweet varieties.
