Default Paphio won't flower

I am afraid that I can't really help you any further -- we have a very hot
environment and therefore just avoid the solid-green-leafed Paphs
altogether. [It's too hot here for Vuyl. Cambria, too.] Kenni

The temp issue can be at least partially answered if you tell us whether
it
has solid green leaves, or variegated/mottled leaves. The latter tend to
be
warm-growers, and exposure to cold would not help. The former can go
either
way, but many of them tend to like cool. How cool is beyond me, as we
don't
try to grow anything cool-ish here, but other posters probably do.

Solid green leaves. This plant sits just in front of the east facing
single glazed window beside the front door. I must get a max/min
thermometer to see what the temp actually falls to just there overnight,
but it was -4C outside overnight and the heating was off between 11pm
and 7am. We heat the house to 18C during the day.

Do paphs need a difference between day and night temps all the time? or
would putting the plant outside during summer/autumn achieve the result?

I am also assuming that by "bract" you mean actual new growths on the
plant,
rather than some type of activity on the flower stem that was in bloom
when
you bought the plant? Good growing, Kenni


Yes, sorry for the lose terminology, they are new growths. The flower
stem is long dead. The main new growth is now at least as big as the one
that flowered.
