Hidden Rose Apple

Overview

Hidden Rose is a red-fleshed apple that originated as a chance seedling in the Airlie area of Oregon’s Willamette Valley in the mid-1900s (commonly referenced as discovered in the 1960s). Parentage is not documented. It has been circulated under multiple names, including Airlie Red Flesh, Mountain Rose, and Newell-Kimzey, with “Hidden Rose” becoming the best-known market name.

Fruit Quality & Uses

Hidden Rose is best known for its striking pink-to-red interior flesh, which makes it especially attractive for fresh slices, salads, and visual culinary uses. Its eating quality tends to land in the “good, crisp, tart-leaning” category.

We obtained cuttings for grafting these originally from Rod McIver, and the guy he got his cuttings from said: "Hidden Rose apple is not anyone's favorite apple but everyone agrees it’s a good apple". Rod argued that it is "like a Granny Smith that has flavor, and a quality Granny Smith." Luke thought the flavor was certainly good when he tried it for the first time on October 19th, 2023 at Rod’s. In general, it also has value for juice/cider where color and acidity can be an asset, though it’s most famous as a fresh “novelty-plus-quality” apple.

Cold Hardiness

Published hardiness guidance for Hidden Rose is typically given as a zone range rather than a verified single “kills-at” temperature, and those zone ratings are often around the Zone 4 class in general references. What matters most for Montana, though, is direct local observation: Hidden Rose survived approximately −35°F unscathed at Rod McIver’s off Rose Crossing in Kalispell, Montana on January 13, 2024. That single event does not prove a universal lower limit for every site and rootstock combination, but it does support treating Hidden Rose as legitimately cold-tolerant in northwest Montana conditions when properly acclimated and sited. So we would list Hidden Rose as a solid zone 3b apple.

Other Notable Characteristics

Firstly, Hidden Rose is an excellent keeper. The photo used was taken in the first week of March, 5 months after the apple was picked off the tree in Kalispell, and had not even shown any signs of breakdown by that point. 

That said, the red flesh is the headline trait, but the broader value is that it pairs that novelty with respectable crispness and a tart profile that many people recognize and enjoy. If you like Granny Smith but want more character (and dramatic color), Hidden Rose is often described as fitting that niche. Certainly much hardier than a Granny Smith.
