  • Deciduous tree, similar in size to the species,  Leaves are cut about halfway to the midrib, forming 6-7 triangular lobes; not as deeply cut as ‘Imperialis’.
  • Sun part shade.  Apparently not too fussy about soil, tolerates dry soils, but is best in moist or even wet soils.
  • Hardy to USDA Zone 4         This selection was found in a garden in France, but similar cutleaf forms have also been found in Sweden and Finland.  A similar cultivar, ‘Imperialis’, has more deeply cut leaves, is weaker growing, more shrub-like, and rather rare in the U.S. (Jacobson, 1996).
