    About this crop

    A large, starchy true yam (not a sweet potato) that is a foundational West African staple, especially in Nigeria and Ghana. Import-Only Note (NYC and RI context): white yam needs an 8 to 9 month frost-free season and cannot be field-grown in the Northeast; it is sourced wholesale through import, often at $3 to $5 per pound.
