Our first time growing this so sorry for the generic description below. We know it is hardy.

A unique hybrid of Aronia and Mountain Ash, Ivan’s Beauty™ is a hardy small tree (to Zone 2) that grows 8–10 feet tall with dark, glossy green leaves larger than those of typical Mountain Ash. In spring, it features abundant clusters of pink-tinged flowers, followed by ½-inch dark purple fruit that can be eaten fresh or made into richly colored, nutritious juice.

These come in bundles of 2 and are 3-5 ft. tall.
