Phyll. dulcis vs. Phyllo. decora
I've decided to plant one of these two species but cannot pick which one. Between the two, I'm looking for the one that will get the tallest with the thickest canes.
I live in USDA zone 6a. Avg winter min is somewhere around -5F (I got access to past 50 years of weather station data). When the temps do drop below zero it is usually only for a couple scattered days in late winter(they haven't done so these past two years). We have pretty consistent snow cover from mid-December through the end of February. Summers are not excessively hot, rarely going above 90F, and moderately humid.
Any suggestions as to which would perform better in my climate? I already have some two/three year old plantings of P. atrovaginata, P. nuda, P. rubromarginata, and P. nigra 'henon' - all of which are doing well. I also have P. aureosulcata 'spectabilis' on the way this spring.
