title: Fraser fir
context: The combination of form, needle retention, dark blue-green color, pleasant scent and excellent shipping characteristics has led to Fraser fir being a most popular Christmas tree species. Growing and harvesting this species for Christmas trees and boughs is a multimillion-dollar business in the southern Appalachians. North Carolina produces the majority of Fraser fir Christmas trees.[12] It requires from 7 to 10 years in the field to produce a 6–7 feet (1.8–2.1m) high tree. In 2005, the North Carolina General Assembly passed legislation making the Fraser fir the official Christmas tree of North Carolina.
question: How long does it take for a live Christmas tree to reach maturity?
answers: 7 to 10 years
