In 2006, Parkland Nurseries in Alberta, Canada, discovered Parkland Pillar birch as a sport of the variety Dakota Pinnacle. It was released to the market after several years of testing, and it is considered a far better plant than Dakota Pinnacle. It is a very resilient tree that was first cultivated by Jeffries Nurseries, which is located close to Winnipeg. It does well in USDA Plant Hardiness Zone 3, making it suitable for growers in Minnesota. The Parkland Pillar is significantly more dense, narrow, and upright in habit.
In 1986, scientist Arthur A. Boe visited the Arboretum at North Dakota State University, located close to Absaraka, to collect seed from a Japanese white birch tree. In 1989, Dale E. Herman discovered an unusual and skinny seedling growing, and to evaluate it, it was studied for several years. In 1999, it was patented under the name Fargo after undergoing extensive testing. The patent is no longer valid but the tree is being sold under the University’s trademark, Dakota Pinnacle.

Dakota Pinnacle Birch vs Parkland Pillar Birch Problems
The Dakota pinnacle birch is susceptible to infestation by leaf miners, aphids, and other insects, similar to many other species of birch. Birches face a major danger from the bronze birch borer. The Dakota pinnacle birch, unlike most others, resists this insect. Diseases such as dieback and canker are also possible on the Dakota pinnacle birch, but they are much less prevalent than pest infestations.
Parkland Pillar Birch, on the other hand, grows rapidly and is not particularly susceptible to insect damage. But this tree cannot withstand bronze birch borer. Because of this, the gardeners need to place Parkland Pillar in a location where it gets the appropriate level of care, including protection from the intense heat of the afternoon sun, enough consistent soil moisture, and possibly some shade. The greatest strategy to keep the birch borer away from the trees is to avoid stress.
