they say it's better to take cuttings in spring before they leaf out fully, but you can see small claws starting. and it has to be on the older growth: gray part of trunk not green from prev year,
but you know that grown in ground plant can take lower temps then the one in pot?the pot gets much colder.
but if that variety is so cold hardy it makes sense to try to grow that for the future, meanwhile taking it indoors for winter while it's in pot.
i missed my window for P. pudica cuttings: they cut the whole bush by like 2/3! so just stubs left. it flowers profusely but has no scent and grows up like crazy getting very leggy. perhaps not a good candidate for pot culture...
My evergreen one (dwarf P obtusa hybrid) is still holding all it's leaves.
i read that if you put them on heat mat like a month before they normally wake up, it will jump start them. Here i see them starting to leaf out in March :), but that is in ground.
mine in pot waited till May last year.
well, half of your winter is over at least and it is still holding up, so good enough for 1st year ?
