Harko Nectarine Tree

Harko Nectarine Tree brings cold-region adaptability together with the rich, melting flavor people expect from a fine yellow nectarine. Its medium fruit ripens to an almost solid deep red, creating a dramatic exterior around firm golden freestone flesh. Each bite is sweet, juicy, and aromatic with enough traditional nectarine tang to keep the flavor lively. The fruit’s good texture makes it satisfying fresh and dependable for baking, preserves, and freezing. In spring, very large pink flowers give the spreading tree enough beauty to serve as an accent in an edible landscape before its heavy crop begins to develop. For gardeners in climates where nectarines can feel risky, Harko offers an appealing combination of cold hardiness, disease resistance, strong fruit set, handsome bloom, and taste-test quality—a practical tree that does not ask shoppers to compromise on pleasure.

Harko needs about 800 chill hours and grows in USDA zones 5–8. This semi-dwarf tree on Citation rootstock ripens from early to mid-July, with timing varying by region and season.

Harko is self-fruitful and capable of bearing alone. Another compatible nectarine or peach may encourage pollinator activity and support fruit set.
