Siberian Crab Apple is a beautiful, cold hardy, ornamental tree. Its stunning white blossoms burst in the spring to produce deep red fruit.

If you are looking for a great landscape or shade tree, Siberian Crab Apple is a beautiful addition to any yard.

As a rootstock, it is one of the hardiest available. Just be aware that Siberian Crab Apple may be incompatible with varieties that don't have crab apple parentage.

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.
