Zone 6a — The Appalachian Hearth
moderate to long growing season · Frost-free ~150-180 days · Min temp -10°F to -5°F
Where mountain folk found sustenance in hollers and hollows. This rugged terrain nurtures rhododendron, yarrow, and coneflower that have adapted to life in the shadows of ancient peaks. The 150-day growing season follows the rhythm of mountain tradition - plant when the dogwoods bloom, harvest before first frost. Your garden carries the wisdom of generations who read nature's signs.
