History: Shizuka (translated as "quiet" or "calm") was created at the Aomori Apple Experiment Station in Japan in the 1930s. It is a cross between Golden Delicious and Indo, the same parentage as its sister apple Mutsu.
Why We Grow It: Although it resembles Mutsu with its large yellow-green fruit, sometimes featuring a reddish-orange blush, Shizuka is sweeter and less acidic. This is an excellent fresh-eating apple for farm gate sales and it also keeps well. It is also great in salads due to its slow browning.
