Pinus nigra 'Oregon Green' / Oregon Green Austrian pine
Pinus nigra'Oregon Green' is a popular tree used as street trees and home landscaping. It is a robust, large selection of Austrian pine with asymmetrical branching holding glossy, dark-green needles that are held somewhat tightly against the branch. After 10 years of growth, a mature specimen will measure 10 feet (3 m) tall and 6 feet (2 m) wide, an annual growth rate of 1 foot (30 cm) or more.
This cultivar originated as a seedling selected in the early 1990s at Van Meter and Son Nursery, Boring, Oregon, USA. The cultivars, Pinus nigra 'Oregon Jade' and 'Select Green' are considered by be synonyms of this plant.

Please help ! I have two Pinus nigra Oregon Deep Greens. They are both three years old, have been growing beautifully, except for this week and a half, one of them looks as if it is dying. We have asked at the local nursery as to what to do... was told "not enough water", however, we put more water, it is getting worse. What can I do? It seems to be turning brow quickly, and we really want to save it! Live in Prescott Valley, Arizona.
Thanks, Betty Schmitt
if you've added water and the color continues to fade, they're probably already gone. The time to add water was probably last year. It often takes a year or two for a conifer to turn completely crispy-brown.
In my opinion, this species is a poor choice for the desert. Next time you should try one of the pinyons; they're much better suited for your climate. Austria is nothing like Arizona, climate-wise.
Hi Lucie ... all pines will shed a certain percentage of old needles from the plant's interior every year in the late summer / early fall. This is perfectly normal behavior for a healthy plant and is of no concern.
Hi Robin ... there is no chart. All conifers grow at different rates for many decades if not centuries ... miniature, dwarf, intermediate and large all refer to growth rates. In tree years, everything will eventually get pretty big.
