It appears that this group of hostas is a case of confused names. Carl Mack who was a horticulturist and nursery owner in the Chicago area accumulated a group of hostas in the 1950s and offered them for sale in the 1960s. The plants were sold under the name of his nursery, "Mackwoods", along with a number. The cultivars listed below are those that have been identified with their real name or which have been named by other Hostaphiles but may have been sold as a "Mackwoods" plant decades ago.
