March 7 - Lovely Fir

Lovely Fir - The Pacific Silver Fir (Abies amabilis), commonly referred to as the Lovely Fir, is native to the Pacific Northwest of North America. It grows at altitudes of sea level to 1,500 m in the north range (Alaska) to 2,300 m in the south of the range, always in temperate rain forest with relatively high precipitation and cool, humid summers.

Pacific Silver Firs can carry the same needles for up to 53 years. They have unique cones that are dark purple in color before maturity, and then turn to a silvery blue color with age.


Jupiter/Moon - These two celestial bodies appear together at sunset on Monday, March 7th.
