Heyer 12 Apple Tree
Couldn't load pickup availability
Heyer 12 was selected by Adolph Heyer in Neville, Saskatchewan, from seed obtained from Morden, Manitoba. The cultivar was introduced commercially in 1950 and is notable for exceptional cold tolerance.
The medium green yellow apples measure about 5 to 6 cm across. Their near white flesh is coarse and acidic, making the fruit better for pies and sauce than fresh eating. It ripens in the early to middle part of the season and stores for only one to two weeks. The productive tree bears young and has strong resistance to fire blight.
