*Click on your approximate section of the country to see a detailed map.

Thuja occidentalis ‘Jantar’ is a narrow upright selection of arborvitae with invigorating, cheerful yellow foliage, with pointier tips at the terminals, especially at the top of the plant. Compared to other yellow selections of arborvitae, it has many more lateral branches which result in a much denser look. As cold weather approaches, a color change begins which results in a mellow orange-yellow for winter. After 10 years in the landscape, one can expect a mature specimen to stand about 6 feet (2 m) tall and 18 inches (50 cm) wide, suggesting an annual growth rate of slightly less than 1 foot (30 cm) a year in most locations.

This cultivar originating as a branch mutation found in 2000 by Jakub Jablonski of Lysomice, Poland on a specimen of T. occidentalis ‘Smaragd.’ “Jantar” translates into “amber: in the polish language and is an accurate description of the plant’s captivating winter color. Breederplants, Inc., Reeuwijk, The Netherlands introduced to the nursery trade and Iseli Nursery, Boring Oregon is credited with the U.S. introduction. This plant was granted U.S. plant patent number PP22296 in 2011. ‘Jantar’ was one of three plants selected in 2016 for the ACS Collectors Conifer of the Year program.

Compared to other yellow selections of arborvitae, it has many more lateral branches which result in a much denser look. When cold weather approaches, a color change begins which results in a mellow orange-ish yellow for winter. This conifer is well suited for making a colorful focal point or statement in a garden without taking up much space. […]

    The yellow ‘Smaragd’ I hear. Let’s add more photos to this page. I’m guessing that many of you have it since it was ‘Conifer of the Year’.

    I have some lovely ‘Jantar’ that are decent-sized. Unfortunately I am a horrible photographer but I’ll try my best!
