Carroll Apple (Spring 2027)

Carroll Apple: Hardy, Early, and Packed with Flavor

We were introduced to Carroll by Roger Joy in the summer of 2016 and were instantly impressed. This apple is a delicious fresh-eating variety, ripening in the Bitterroot and Missoula Valleys in late August, making it a fairly early-season apple.

It has a spicy-tangy sweetness that stands out and makes it a favorite for snacking.

Origins and Breeding Background

Carroll was developed at the Morden Research Breeding Station in Manitoba, Canada and is known for its exceptional cold hardiness, surviving temperatures down to -50°F or colder.

Its Melba parent (a McIntosh seedling) contributes the dominant white flesh gene commonly found in McIntosh derivatives. The real game-changer for hardiness, however, comes from its other parent—Moscow Pear Apple—which likely boosts its survivability well beyond McIntosh’s typical -40°F threshold.

Fruit Qualities and Uses

Carroll produces large apples, typically 3 to 4 inches in diameter, with a distinctive flavor profile that combines spicy, tangy, and sweet notes—making it an excellent choice for fresh eating. Though we primarily enjoy it right off the tree, it’s also reported to perform well in pies and sauces, offering rich flavor complexity when cooked. One notable trait of Carroll is that it’s among the first apple varieties to defoliate in the fall, often signaling the seasonal shift before others. According to Roger Joy, “The canopy is vigorous and rounded, with lateral branches originating from wide angles, capable of supporting heavy crops of this wonderful fruit.”

Cold Hardiness and Growing Recommendations

Carroll is a solid Zone 2 apple, making it ideal for growers in extremely cold regions. All of our Carroll trees are grafted onto Dolgo rootstock, one of the hardiest rootstocks available, known for thriving in climates that dip below -50F or more, as well as Bud 118 (Hardy to about -45 to -50F).
