The lady is gathering Plumeria blossoms for use in offerings at the small, simple temples you might find around town. There were several of these at Waka Di Ume which were carefully tended each day. Nearly all the houses along this street had temples in their courtyards, too. You can see their roofs as you can behind the lady here. The blossoms are also placed in the offerings that you see on the street as at her feet.
