Characteristics of Toringo Crabapple Tree (Malus sieboldii) in the Wild

Malus sieboldii
Toringo crabapple or Siebold’s crab (Malus sieboldii syn Malus toringo) is a species of tree from the Rosaceae family. The tree is found in mixed forests, among the bushes, on the slopes of mountains at an altitude of 150-2000 m above sea level in China, Korea, and Japan. Due to its natural habitat on the slopes of the mountains, it is sometimes referred to as the Wild apple.

Toringo crabapple makes a great ornamental tree because of its showy flowers in spring. Outside of its place of origin, this tree is cultivated as a complementary tree to the landscape and as a bonsai specimen.
