Ornamental and Aromatic Benefits for the Garden
One of the most immediate and delightful benefits of a 4 o'clock plant is its role as a stunning ornamental in a home garden. Known for its vibrant, trumpet-shaped flowers that bloom in the late afternoon and fill the evening air with a sweet scent, it's a perfect choice for garden beds near patios, walkways, or windows where the fragrance can be enjoyed. The flowers appear in a mix of striking colors, including pink, yellow, white, and red, with some varieties even featuring multi-colored streaks on a single plant.
Beyond its evening spectacle, the plant's bushy growth habit makes it an excellent choice for borders, hedges, or large containers. In warmer climates (USDA Zones 9-11), it can act as a perennial, while in cooler zones, it is typically grown as an annual, although its tubers can be overwintered indoors. Its lush, dark green foliage provides a beautiful backdrop for other flowering plants throughout the day.
Attracting Pollinators and Deterring Pests
Gardeners seeking to create a vibrant and healthy ecosystem will find the 4 o'clock plant particularly beneficial. The sweet evening scent of its blossoms is a powerful attractant for nocturnal pollinators, including hummingbirds and certain moths, contributing to the biodiversity of your outdoor space. This provides a crucial food source for these creatures during hours when most other flowers are closed.
In addition to attracting beneficial wildlife, the plant also serves as a natural pest deterrent. The roots of Mirabilis jalapa have been noted to repel certain nematodes in the soil, protecting nearby plants from damage. For gardeners looking to manage pests naturally without chemical interventions, integrating 4 o'clocks into their landscape design is a practical strategy.
