Hi,Folks, does anybody have any idea what colour is the Passion Flower
variety called 'Sabine'

I think you may be confused, Sabine isn't a variety.
His name is at the end of some botanical names because he was a
botanist......
e.g.
Passiflora caeruleo-racemosa Sabine


Sabine appears to have been a horticulturalist. He isn't responsible for
many botanical names, and they were published either in the Transactions
of the Horticultural Society, or by other authors.

IPNI doesn't have Passiflora caeruleo-racemosa Sabine, but their
coverage of horticultural hybrids (this would be P. caerulea x P.
racemosa) is incomplete. Since they omit this I can't safely assume that
the lack of records for other names in Passiflora due to Sabine means
that this was the only name in Passiflora that he introduced, but I
think it likely that this is the case.

This being the case, the plants under discussion should be P.
caeruleo-racemosa.

[Some time ago there were plants in circulation as Papaver Tatewok. They
turned out to be Papaver miyabeanum Tatew.(aki). This looks like a
similar case - the authority having been mistaken for a cultivar name,
and the epithet elided.]

Passiflora caeruleo-racemosa has red flowers. (Looking at a photograph
I'd narrow that down to deep crimson-pink.) But I can't be sure that
they aren't cultivars with other colours. (RHS Plant Finder has no
entries under Passiflora caeruleo-racemosa or Passiflora
caeruleoracemosa, so it doesn't help here.)
