I think this is a false orange blossom, although I'm open to correction. [Note: changed to Mock-orange in title.] A sample of the leaves is below for ID purposes. But let's start with the good photos.

Of note, the SWIR photos looked identical to the NIR ones for this flower, unlike for the buttercup.
