Vermilion Sweet potato
✓ In your garden
Vermilion is an orange-fleshed sweet potato, ready in about 100–110 days. You grow sweet potatoes from “slips” — rooted sprouts — not seed or tubers. Plant them once the soil is warm, give them a long, hot summer to sprawl, and dig before frost. Then cure them warm for a week or two, which heals the skins and turns the flesh sweet.
“A heat-loving root that cures sweet and stores for months.”

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).

Growing Vermilion — the things that trip people up
- Sweet potatoes grow from slips — rooted sprouts you buy or start from a tuber. Plant them only once both the air and soil are warm; they’re tropical and won’t move in the cold.
- Dig carefully before the first frost (frost damages the roots), then cure them for a week or two somewhere warm and humid. Curing heals nicks, sweetens the flesh, and lets them store for months.
