I planted one vine along my own back chain-link fence here in zone 5, and from the kitchen window the split is hard to miss. The sunny west end drips with creamy panicles by August. The shaded north end, tucked behind the maple, stays green and leafy and bare. Same plant, same roots, two different stories. I noticed it the first summer and have watched it repeat every year since.
So here is your answer. The right silver lace vine light is full sun to part shade, but the plant clearly prefers full sun. It will grow in either spot. It only flowers hard in the bright one. The short version is simple. Give it sun, and treat shade as a fallback if you have no better place for it. My own fence shows you the difference in a single glance.
Here is why the west end of my fence wins, and why yours will too. Silver lace vine flowers on new wood, the fresh growth it pushes out each season. Direct light fuels that growth and the flower buds that ride on it. More sun means more new wood. More new wood means more of those fragrant white panicles. Your bloom and your privacy screen both run on the same engine, so the sunnier the spot, the more of both you get.
Shade flips the math on you. A vine in deep shade still climbs and still fills in with leaves, so it can pass for healthy at a glance. But it builds far less of the flowering wood. So the silver lace vine bloom thins out, and the fragrance fades right along with it. You end up with a green wall instead of a white one. That is fine if leaves are all you want. It is a letdown if you planted it for the show.
Aim for at least six hours of direct sun a day and you will get the heaviest bloom. That is the dividing line between a vine that flowers and one that mostly just leafs out. A west wall, a south wall, an open fence, a sunny arbor, all of these hit that mark in most yards. The more light your panicles catch, the denser and showier the display gets. This is also why a vine in a bright spot reads as a thicker, faster screen by midsummer.
Part shade is not a dead end, though, so do not write off a dimmer corner. The vine grows fine in four to six hours of sun and shrugs off a half day of shade without sulking. You simply trade some flowers for the convenience of the spot. If your only open trellis sits against a north wall, the plant will still cover it. Just expect fewer blooms and a quieter scent than the sun-soaked version puts out.
So place it where it earns its keep. Put it on the brightest fence, wall, or arbor you have, somewhere you want both a fast privacy screen and that late-summer fragrance drifting past. Six hours of sun or more gives you the full show that makes this vine worth growing. If full sun is off the table, plant it anyway in the brightest spot you can spare and let it climb. It is forgiving about light, even though it saves its best for the sun. Match the spot to what you want, and you will get the result you pictured.
