Malus × zumi (or Malus zumi) is a naturally occurring hybrid species of crabapple in the family Rosaceae, native to Japan, and a garden escapee in the US state of Ohio.[1] Its parents are Manchurian crab apple Malus mandshurica and Siebold's crabapple Malus sieboldii.[2] It is used as a salt‑tolerant rootstock for apples, Malus domestica, as it can survive NaCl concentrations up to 0.6%.[3] A number of ornamental cultivars are available, including 'Golden Hornet' and 'Professor Sprenger'.[4][5]
