Bigcone Douglas-fir (Macrocarpa)

The Bigcone Douglas-fir (Macrocarpa) is generally described as a perennial tree. This is native to the U.S. (United States) has its most active growth period in the spring . The greatest bloom is usually observed in the early spring, with fruit and seed production starting in the summer and continuing until fall. Leaves are not retained year to year. The Bigcone Douglas-fir (Macrocarpa) has a long life span relative to most other plant species and a moderate growth rate. At maturity, the typical Bigcone Douglas-fir (Macrocarpa) will reach up to 75 feet high, with a maximum height at 20 years of 24 feet.

The Bigcone Douglas-fir (Macrocarpa) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -13°F. has high tolerance to drought and restricted water conditions.
