Understanding Zone 6 and Its Growing Season

Zone 6 typically experiences minimum winter temperatures between -10°F and 0°F. This allows for a diverse range of perennials and annuals that can flourish in late summer and early fall. The growing season generally extends from April to October, with some plants blooming well into November.
