(Barney Turkish Fir, Turkish Fir)

The Turkish fir is every bit like a Nordman fir except it doesn't mature nearly as large and has a greater tolerance to alkaline soils. Turkish fir grows naturally at high elevations in the mountains from roughly Athens, Greece to Istanbul, Turkey and the adjacent Bithynia region. Turkish fir essentially is an isolated population of Nordman firs that evolved and survived on cooler, northern-facing slopes in the region.

Turkish fir has an upright, narrow and columnar form with a partially rounded...
