have a couple of very big nz flax plants
got snowed on this week and a lot of the exterior
leaves got leveled
got the snow off them asap but they are still down
any thoughts about them, the leaves, springing
thought about running a rope all around the plants
to give them a temp lift?
what is the physical mechanics going on here?
Not sure what your experience might be, but my recollection is that Phormium
hybrids, like 'Sundowner', 'Apricot Queen', 'Maori Maiden' can't stand
temperatures below about 20 F.
I'd probably do what I could to protect the growing crowns, including tying
leaves up over them.
They are reliably winter hardy to zone 8, 20F. Many of the hybrid cultivars
(with P. cookianum parentage) are somewhat hardier, specially if drainage is
very good. These originate from high mountainous, even alpine, areas of NZ
and can tolerate quite a lot of cold weather.

What you say is true. Phormium cookianum ssp. cookianum occurs in the
highest altitude regions of New Zealand and would be the most tolerant of
cold. The problem is identifying the cultivars of Phormium cookianum ssp.
cookianum that are specifically the most cold hardy. Much experimental
testing for cold hardiness needs to be done. An effort should be made to
produce improved cold hardy cultivars.
There are many Phormium cultivars in the trade but most of them, especially
those of P.tenax, would not be expected to be cold hardy.

well they have survived at least 10 winters and i know it
has been in the 20's every now and then for periods of time
spent 2+ hours yesterday ropping and belting up the leaves
and cutting dead leaves off the bottom
left it bundled up
good idea or bad?
only did it to one of the plants
plan/theory is to gradually release the ropes over a couple
weeks hoping that this will restore the uprightness
good or bad idea?

You still haven't answered the question you were asked, stubborn Billybob.
Exactly where on the planet are you?
How about telling us which USDA hardiness zone you are in too?
Bundling up the leaves is a bad idea and a waste of time. The ropes
rigmarole is a waste of time.
It is far more important to protect the rootstock from cold. Try mulching
the plants instead.
