P. saccharata is the species that is most likely considered to be
evergreen
but I don't consider any pulmonarias to be truly evergreen, certainly not
like a hellebore or euphorbia. I grow P. saccharata 'Sissinghurst White'
and by November or so, the foliage looks pretty ratty and I cut it back.
In
most seasons they will respond by producing a hint of new foliage, but no
active growth and no full development of new leaves until spring. How they
may perform in warmer winter situations I can't say.

Probably go ratty slightly earlier, depending on heat buildup/accumulation.

btw, here it is the end of February and my Sisiinghurst White is in full
flower with leaves elongating as we speak. These are excellent early
season
plants for the shady garden. Just brought in 'Benediction' at the nursery
and it is stunning - heavily covered with intense, sky-blue flowers. This
is
a Great Plant Pick for you PNW gardeners.

So maybe you can calibrate these flowering times to other flowering plants.

I'll take a guess that you're about 2 weeks from initial flowering of common
purple leaf plums?
And Benediction began almost 2 weeks ago?

and do some Pulmonaria not require dividing?

I've never had need to divide any of mine, but they can be divided easily.
