Sievers Apple

Malus sieversii is a wild apple native to the mountains of Central Asia in southern Kazakhstan. It has recently been shown to be the primary ancestor of most cultivars of the domesticated apple . It was first described as Pyrus sieversii due to its similarities with pears in 1833 by Carl Friedrich von Ledebour, a German naturalist who saw them growing in the Altai Mountains. Malus sieversii grows in many different habitats. They prefer high temperatures and short winters, but they are also found in the Tian Shan Mountains with long and harsh winters. They are distributed mainly within the Yili valley as the damp climate is suitable for their growth.
