Flowering crabapple trees paint spring with floral finery that’s tough to beat. ‘Thunderchild’ is no exception. Blush pink blossoms open before deep purple leaves appear, releasing a delicate fragrance. All this beauty belies a tough-as-nails constitution, marked by strong disease resistance (no fireblight here!) and strong winter hardiness. Mature size is 15 to 20 feet tall and 15 feet wide. Hardy in zones 3-7.
