Tropical plants in zone 6a colorado

[COpalms]

I made a post a bit ago talking about some of the tropical plants I was zone pushing here in zone 6a, Colorado. They are Cycas revoluta, Eucalyptus cinerea, and Monstera deliciosa. Starting with the Cycad, sago palm, I have no idea if it's dead or alive. I should apparently not uproot it or do anything with it yet because iits to early to tell whether it will continue growing or not, but I wouldn't be surprised if it were dead. There is no spear pull or rot; however, I did not protect it probably as much as I should have, and its leaves died due to snowfall indirectly touching the fronds on the frost cloth. Regarldess I will wait and see what happens. I should also mention it has been a relatively mild winter with not much snow and the lowest temp being about 0-1 degrees farenheight (-17 degrees Celsius). My eucalyptus is still alive with some mild damage and dieback, and someone mentioned in my last post that cold damage does not show until temps warm up, which makes sense since it did not get any damage until warmer temperatures arrived. My monstera is alive, but i dont know if it will come back; however, apparently, it might.  Its stem is still green and alive with nodes and aerial roots, but no leaves, so i dont know what to expect. I will mention I have an Ensete ventricosum 'maurelii', which is supposedly hardy in only zones 9-11, but mine survived close to a wall and mulched. The canna lillies I did not dig up but are growing after I unmulched them, and my blue passionflower is still green and bendy at the base of the stem. Any tips or helpful advice, or anything? Thanks!
