AC™ Harblaze is a Stark Delicious x Hardired cross, which makes it a second generation graduate from the Harrow Research Station. In various field trials, AC™ Harblaze has shown impressive performance compared with other nectarine varieties, including Harko. It consistently came out on top for winter hardiness, canker resistance, fruit size, firmness, and flavour. Although it has lower productivity numbers, this really translates to say less fruit thinning is required. AC™ Harblaze is a real stunner in spring with large, showy pink blossoms, but the real reward is the glossy, scarlet fruit.
SELF-FERTILE* / ZONE 4/5 / HARVEST: MID AUG.
Stop! Do not plant your peach or nectarine tree in that sheltered nook of the south side of your house. Although well meant, this very common mistake is almost certain to doom your new tree. Of course extreme cold is hard on peach trees, but the warm noonday sun on a late winter day is actually worse. A dark tree trunk will warm up considerably but then the temperature drops and the bark refreezes. To avoid this fluctuation, look for a planting site in the winter shade (north side) of a building or group of evergreens. In other word, close enough to the building to be shaded from the low winter sun but far enough back to get full exposure in the summertime when the sun is high. The goal is uniform cold so as
not to interrupt dormancy. Some growers white wash the trunks and lower branches of older peach trees in late fall with a cheap interior latex paint to protect from sun damage in winter. Young trees should have trunks wrapped with a light coloured blanket or covering.

While I have only had the tree since May 2026, and weather in Alberta has since been snow, hot then freezing, and then 300mm rain, Harblaze has started leafing out! I am very grateful for Whiffletree’s best practices guide that came with my order and the funny but true advice to hard prune them once in the ground. Oh the sadness, but I know it is an investment for the current health and future abundance of theis nectarine tree.
