Blue Conifers - Humidity
I have spent a lot of time researching which species do best in humid (east coast) or (PNW) conditions. It's 100% clear that Picea pungens do not like it here. They will tolerate it for a while, but always end up looking terrible. Interestingly, I have found Picea engelmannii to be very happy here... it's strange, because a lot of documentation suggests they are nearly identical and both are high risk for needle cast. I found a paper from the early 1900's at the Arnold Arboretum stating "From all points of view Picea Engelmannii is now the
best Spruce which has been planted in the Arboretum." .
I wanted to share that for others. It is the Arnold Arboretum's experience, and my own, that Picea Engelmannii is far superior to Picea pungens for our humid east coast.
Abies concolor is also excellent for this environment. Abies concolor flourishes in the Arnold Arboretum. Along with Abies homolepis, it was one of thefavorite conifers of Charles Sprague Sargent
My question to the forum is about the following species and how they do in humid conditions. Does anyone have experience with fungus, needle cast, or other diseases for these?
-Abies lasiocarpa (specifically var. Arizonica)
- Abies pinsapo
Ironically, the nearly native Abies balsamea and Abies fraseri are also not options for this area. They only perform well at colder, higher elevations. I am looking to add more blue cultivars to my collection and want to make sure I focus on species most well suited. Picea pungens cultivars are my favorite and so vast, but they just don't work.
