Abies concolor 'Tubby' is a dwarf selection of white fir that, in typical fashion of dwarf firs, will have a globose form when young, later becoming broadly conical with age. Branching is tight and uniform; and foliage is species-typical blue-green in color. After 10 years of growth, a mature specimen will measure 24 inches (60 cm) tall and 18 inches (45 cm) wide, an annual growth rate of around 2 inches (5 cm).
This cultivar originated as a witch's broom seedling selected by Joe Stupka of Pulaski, Pennsylvania and introduced to the nursery trade by Rich Eyre of Rich's Foxwillow Pines Nursery, Woodstock, Illinois.
