The vine characters here are not satisfactory. It is only moderately productive and for some years has been affected with chlorosis.
Marie Louise was originated by Theophile Huber of Illinois City, Illinois, about 1880. Besides the characters of the variety, the work of the originator would indicate that it is a Concord seedling. There are no records of its ever having been widely disseminated.
Vine intermediate in vigor, not hardy nor productive. Canes short, not numerous, dark brown; tendrils continuous, bifid. Leaves small to medium, intermediate in thickness and smoothness; lower surface tinged with bronze, heavily pubescent. Flowers nearly fertile, open in mid-season; stamens upright. Fruit ripens about with Worden, does not keep well. Clusters small to medium, short, slender, cylindrical, usually with a small single shoulder, rather loose. Berries small to medium, roundish to oval, pale green with tinge of yellow, covered with thin gray bloom, shatter badly, not very firm. Skin thin, of medium toughness. Flesh pale green, tender, sprightly, somewhat vinous, sweet at skin to tart at center, good to very good in quality. Seeds separate easily from the pulp, not numerous, small, short and broad, plump.
