My Passiflora "Clear Sky" has also set fruit, and one has ripened,
with 13 viable-looking seeds in it. I shall see whether I can get
them to grow next year.

I see it's a tetraploid. Does that affect seed viability?

My understanding was that it was sterile, but I may have been
confusing it with another plant. Anyway, it's the first time it
has done it (in a sun-free location, too), and it will be quite
interesting to see if I can get any germination.

I picked my maypop fruit, on the grounds that it isn't going to
ripen further, and it has some very viable-looking seeds in it.
The chances of there being another P. incarnata in insect distance
is very low, so I wonder if it really IS always self-sterile, can
be induced to set (non-viable) seed by another species, or might
be occasionally self-fertile. I shall see about both next year.
