Thunderchild Flowering Crab is a hybrid crab apple known for its attractive and fragrant dark pink blossoms and deep purple mature leaves.

Tree farmers will find this hybrid appealing as a pollinator for other apples, while home growers will enjoy the red pome's ability to attract flocks of Cedar Waxwings in the early spring.

This species is reportedly resistant to fireblight.

Ottawa 3 Rootstock is the most dwarfing rootstock to come out of the cold-hardy breeding program by the Agricultural Canada Research Station in Ottawa. It produces dwarf to semi-dwarf trees that are 45-55% of standard size. Due to its superior hardiness, it is well adapted to Canadian weather conditions.

It originates from Malling 9 (M.9) and the Robin Crab and is considered more dwarfing than Malling 26 (M.26) and more vigorous than Malling 9. Ottawa 3 Rootstock is very productive and bears fruit early, often requiring structural support when young.
