I am very fond of Holboelia latifolia but the last few nights have stripped
the flower buds, ditto Akebia quinata, but that tends to be semi evergreen
if frosted.

I shall see if my Akebia quinata flowers, though my experience is that
it is tolerably frost-resistant - on the other hand, it is reliably
deciduous with me, even in a very mild winter.

So far, I have not got Holboellia to flower, as the buds get frosted
by the slightest nip - even the new shoots die, but that is scarcely
a matter of concern, as it merely acts as a bit of pinching out.

I don't think that a mere -7 Celcius will be enough to worry either
Clematis armandii or Passiflora caerulea - curiously, I have found
the flower buds of the former to be more frost-resistant than the
shoots. And, of course, the latter is semi-evergreen, indeed almost
herbaceous, with me.

Most the above is the difference between where you live and where
I do.

What will be nasty is if this weather is followed by a long spell
of cold and wet, as that could let the bacteria and fungi into the
frost damage. That is more likely to be your problem than mine.
