cute large pinkish somewhat see through seeds Sounds like the pearly pink seeds of the Surprise lilies of my California childhood -- which apparently were Amaryllis belladonna. Here's a site with photos of A. belladonna seeds. (A nursery I never heard of. But all the other photos were from flickr, pinterest, or The Site Which May Not Be Named.) https://www.trionursery.com/store/amaryllis-belladonna-seeds

Catharanthus roseus- Madagascar periwinkle. (Toxic but medicinally important)

Definitely Crape myrtles. They bloom around here from about late July into October. Their leaves also color unbelievably in the Fall (bright orange, yellow, and red--all on the same plant). I have the lavender/magenta variety and in the Spring will be planting the red "Dynamite" variety.

This came up in my lawn, near a flower bed I have a couple climbers in. Pink, small flower , maybe 3”, ith nice scent, maybe a little “lemony “!!!
