RENAISSANCE REFLECTION® is a cultivar of the iconic paper bark birch tree reported to be resistant to bronze birch borer, which is known to infect the species in the southern portion of its native range. This cultivar is also more heat resistant than the species.

The primary ornamental feature of birch trees is the bark. Many of the common names of birch trees refer to the color of the bark -- white, gray, yellow or red. Another signature bark characteristic is its habit of separating into thin sheets; Native Americans used this property to harvest the bark from fallen paper bark birch trees to make canoes, bowls and shelter -- practical as well as beautiful. A strong secondary ornamental feature is the usually colorful golden fall foliage. Given their preference for cool weather and acid soil and their susceptibility to bronze birch borer infestations, birch trees can be challenging to cultivate in the Chicago region.

The genus Betula includes an indeterminate number of species of the birch tree; estimates range from 30-60. They are native to the cooler, temperate and sub-polar regions of Asia, Europe and North America -- generally preferring long cold winters and short mild summers. The Chicago Botanic Garden's collection contains more than 40 varieties among its more than 500 birch trees.
