How to Grow and Care for Four O’Clocks Mirabilis jalapaDid you know there’s a plant named after a time of day?
And while you may recall the rather old-fashioned four o’clock (Mirabilis jalapa) from visits to Grandma’s house, the name of the plant isn’t a reflection of when our older relatives often tend to eat dinner.

The flowers bloom in late afternoon in response to a temperature drop. Nocturnal moths and other nighttime pollinators are attracted to their nectar.
They remain open throughout the night and into the morning when temperatures rise and the flowers wilt. Like daylilies, four o’clock flowers bloom just a single time, then fade and eventually fall off the plant.
On cloudy days, the flowers open earlier and sometimes won’t close at all. Again, this is not due to a lack of light, but rather, to temperatures that are lower than usual.
Many gardeners find deadheading unnecessary because even the wilted blooms are attractive, and this plant blooms profusely with or without deadheading.
