Did You Know?
1. Four o’clocks (Mirabilis jalapa) are not only popular garden flowers but also possess a distinct nocturnal behavior. Their blossoms typically open in the late afternoon, around 4 pm (hence the name), and close again by morning.
2. Despite their delicate appearance, four o’clock flowers are highly resilient and drought-tolerant. They are native to arid regions of the Americas, particularly Mexico and Peru, where they can survive long periods without significant rainfall.
3. Four o’clocks exhibit an intriguing phenomenon known as “polyploidy,” which means they have multiple sets of chromosomes. This unique genetic feature allows for an array of flower colors, including shades of red, pink, yellow, white, and even bi-color varieties.
4. The seeds of four o’clock plants are somewhat charismatic—their shape resembles tiny black buttons. However, there is an interesting twist: if you were to chew on these seeds, they would taste remarkably similar to sunflower seeds!
5. Although four o’clocks are most often grown as annual plants, they can also behave as perennials in warmer regions. With proper care, including winter protection or natural insulation, these charming flowers can persist for multiple growing seasons.
