GoldRush came out of a three-state collaboration between Indiana, Illinois, and New Jersey agricultural experiment stations, grown from Golden Delicious seed pollinated by various cultivars. The goal was a practical apple: one that resisted scab and mildew, showed some tolerance to fire blight, and produced fruit worth eating. The result is a late-maturing cultivar with bright golden-yellow skin, harvested mid-to-late October, that just keeps getting better in cold storage — the sharp acidity softens over two to three months in the refrigerator while the crispness holds.

Grafted onto semi-dwarf M-7 rootstock it reaches 12 to 16 feet; on dwarfing M-26 stock, 8 to 12 feet. The tree grows with a strong central leader and naturally wide branch angles, making training relatively straightforward. It is not self-fertile and benefits from nearby pollinators, along with healthy mason bee populations to carry pollen effectively. Thinning the fruit — removing some of the developing apples in early summer — produces the best quality and avoids the exhaustion that leads to biennial bearing. Sooty blotch and cedar apple rust are the main disease concerns.
