all summer long, i have been itching to find out the name of this plant. it has wide-brimming white flowers that are open by early morning, but once the sun peels out and shoves shadows out of the way, the blooms tighten up and close for the rest of the day.
the little white dots in the middle of this scene below are the flower.
they are like puffs of whipped cream on paper-thin pieces of nature attached to greenery.
by searching on google, i discovered a blogspot page that finally answered my question-- this is called moonflower. unfortunately, i can't find that same blog again to give the blogger credit.
moonflower is related to the morning glory, which makes good sense in that it opens in the evening and closes up by morning.
