Buckthorn is described here as a hardy hedge and ornamental foliage shrub, not as a documented fruit cultivar. Northwest Nursery Co. called it one of the best plants for hedges and foliage effects, with dark olive green leaves that stayed attractive through the season [S1]. Fruit Growers Service Co. also sold it for northern hedging and called it hardy and dependable in the North [S2].
The sources do not give a species name, parentage, breeder, nursery introduction date, or cultivar origin. Both records are nursery catalog entries about landscape use. Buckthorn appears in hedge and boundary sections with other shrubs and small trees, not in a fruit section [S1] [S2].
The plant is described mainly by foliage and hedge growth. Northwest Nursery noted its dark, rich olive green leaves, its value as a background for flowering shrubs, and its ability to form a dense, thick hedge when trimmed low at planting [S1]. Fruit Growers Service Co. recommended it for formal sheared hedges and described the foliage as dark green [S2]. Small thorns were said to appear on older plants [S1].
These sources report no edible fruit qualities, ripening season, storage behavior, culinary uses, or pomological traits. Its documented value is ornamental and structural: hedges, screens, boundaries, and background planting [S1] [S2].
Hardiness is the clearest point of agreement. Northwest Nursery placed Buckthorn among hedge plants that had proved absolutely hardy in the Dakotas and said it was hardy and thriving well in the region [S1]. Fruit Growers Service Co. called it hardy and dependable in the North [S2]. No explicit zone rating is given.
The entry remains taxonomically incomplete. The page context suggests Rhamnus or Buckthorn, but the sources do not identify a species or named cultivar. The main uncertainty is whether this archive record belongs as a pomological entry, since the evidence supports a hardy ornamental hedge shrub rather than an edible fruit selection.
