“PINES FOR THE MIDWEST RESINÂS PICKS
Pinus armandii  make sure you get seed from the northernmost origins (Gansu, Shaanxi); the most widespread origins in cultivation are from the south end of the range in Yunnan and only zone 8 hardy
Pinus banksiana  some susceptibility to pine wilt nematode (PWN)
Pinus bungeana  well worth a try, give it a well-drained site
Pinus cembra  worth a try, but might suffer from summer heat/humidity
Pinus contorta latifolia  likely to suffer from summer heat/humidity
Pinus densiflora - susceptible to PWN
Pinus echinata  should do very well
Pinus engelmannii (doesnÂt like humidity)
Pinus flexilis  may have problems with summer heat/humidity, also susceptible to white pine blister rust (WPBR)
Pinus koraiensis  should do well
pinus leucodermis  should do well. Name correction: Pinus heldreichii
Pinus monticola  likely to have problems with summer heat/humidity, also WPBR
Pinus mugo  should do well
Pinus parvifolia - should do well
Pinus peuce  (Macedonian pine) should do well
Pinus palustris - not hardy in z5
Has a deep taproot: source: Gymnosperm Database:

Pinus ponderosa - some probelms with summer heat/humidity, tends to vary unpredictably from individual to individual (so plant dense, and cull out the ones that get needlecast badly)
Has a deep taproot: source: Gymnosperm Database:
http://www.conifers.org/pi/pin/engelmannii.htm
Pinus pumila - summers much too hot for this
Pinus pungens  should do well
Pinus resinosa - should do well
Pinus rigida  should do well
Pinus strobus  should do well
Pinus strobiformis  should do well, but susceptible to WPBR
Pinus tabuliformis - (note spelling) likely to have PWN problems
Pinus taeda  marginally hardy; northern origins should do well, southern origins (widely sold for forestry) won't be hardy
Pinus mugo subsp. uncinata - should do well, but PWN may be a problem later
Pinus virginiana  should do well
Pinus wallichiana - not hardy in z5
Pinus x schwerinii - should do well
Pitch x loblolly pine - should do well
Pinus ayacahuite x strobus - should do well; may be susceptible to WPBR

"What are my chances with these Please? "
Abies chensiensis (note spelling ;-) - fairly good
Abies squamata - nil (needs cold summers)
Abies magnifica - low
Abies magnifica var. shastensis (what's the difference)? - low (differs in cones with exserted bracts)
Juniperus formosana - very good
Juniperus monosperma - poor, likely to get diseases related to high humidity
Picea schrenkiana - fair
Picea breweriana – poor»
