✓ In your garden
Case Knife is a dry bean (pole), ready in about 100 days. Let the pods dry on the plant, then shell the beans for soups, chili, and storage. Beans are easy warm-season crops — sow the seed straight in the ground after frost (they hate being transplanted), and give it a tall trellis or poles to climb.
“A bean grown to shell and dry for the pantry.”

Zone 6bGreenhouse or cover on: your start slides ~4 weeks earlier and your harvest stretches ~3 weeks later (shown striped).
Planting seeds straight in the ground only works where the season's long and warm — most gardeners start seeds indoors or buy young plants, or you'd pick your first tomato right as frost hits.
Comfortable — first ripe fruit lands around early Aug, well before your typical frost (~late Oct).
