Here's the vine that's closest to the street. I'm calling this the "A" vine.
This was 9:00 PM in the evening; it's a 15 second exposure to get that much light. Full resolution, here.
There were at least 2 dozen blooms tonight, of which 5-6 were easily reachable on foot, and one more with a stepladder. I have about a teaspoon of pollen in my fridge, because some of my own vines will bloom within a week.
I didn't have any of my own pollen with me, so I couldn't pollinate this vine, but I will bring some next time I visit. I did hand-pollinate these flowers with their own pollen, though I suspect they're self-infertile (but I don't actually know for sure).
The B vine (also outside the gate) had only one bloom, but there are more buds ready to pop over the next several nights.
The C vine (inside the gate) also had lots of blooms tonight, but I couldn't get inside.
None of the flowers I hand-self-pollinated set fruit, so apparently the A vine is self-infertile, and I never did get around to bringing some foreign pollen to it. Maybe next bloom cycle, if we have one, or perhaps next year.
A cutting of S-8 or other pollinator will take years to get to flowering stage.But I had another idea--What if I were to graft some S-8 on these vines?
Can one graft DF onto descending branches? Is it hard to ensure contact on an upside-down graft? When causes a grafted piece to flower? Its own maturity, or the maturity of the host plant? Or a combination of both? When is the right time to graft?
