Juniperus virginiana 'Corcorcor' EMERALD SENTINEL™ USPP5041, is an upright, rather narrow selection of eastern red-cedar with bright green foliage. This is a female, fruiting cultivar that is deemed to have superior disease resistance and is considered one of the toughest plants in the nursery trade. After 10 years in the landscape, a mature specimen can measure up to 20 feet (6 m) tall and 8 feet (2.6 m) wide, a rate of growth approaching 2 feet (60 cm) annually. It is quite suitable for hedgerows where arborvitae may be inappropriate.
This cultivar originated as a chance seedling selected by Clifford D. Corliss and Brothers Nursery Inc., Ipswich, Massachusetts. Refer to this link for a complete description of the plant patent pertaining to Emerald Sentinel™.

20 years ago before I got into gardening we had a company design and install a shrub bed. 5 Emerald Sentinel Junipers were planted along the street. They all died ( as I learned the hard way the spot was too wet) but we had 2 seedlings surviving in a dryer spot. They do not have berries. Question is: Do I have 2 males? Can I plant a 'Blue Arrow' next to the ones I have in the dryer spot and expect berries on the Blue Arrow?
I am trying to get berries for the birds.
Any comment of what works and what does not is welcome.
Eva, I have one as well and it is very hardy. These plants are asexual, so they reproduce without an opposite sex. This year mine was particularly loaded with berries, which the birds have enjoyed immensely. This link will provide more insight into the plant. Good luck https://patents.google.com/patent/USPP5041
