Q.outdoor potted plant
Lowes sold this plant as Exotic Angel. They are potted and on the front porch facing west. They are very healthy. The flowers only stay open 24 hours and never open again. Others will open but no re-opening.
The Exotic Angel name is a brand name of a greenhouse, Hermann Engelmann Greenhouse Inc.
They grow over 400 varieties of houseplants.
Look for an additional tag that should have come with your plant. It should have the variety of plant you purchased.
It is not uncommon for some flowering plants to have blooms that last just one day.
