The Common Juniper (Communis) has a long life span relative to most other plant species and a slow growth rate. At maturity, the typical Common Juniper (Communis) will reach up to 10 feet high, with a maximum height at 20 years of 5 feet.

The Common Juniper (Communis) 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 low vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -43°F. has high tolerance to drought and restricted water conditions.
