4 Oclock Flowers

Four o’clock flowers, also known by their scientific name Mirabilis jalapa, are fascinating and highly distinctive plants that belong to the family Nyctaginaceae. They are named “four o’clock” because they tend to bloom in the late afternoon, typically around 4 PM, and continue to display their blossoms until the following morning. This behavior helps them avoid the midday heat, preserving their delicate petals and appealing aroma.

Description:

• Flowers: The flowers come in a variety of vibrant colors including pink, red, yellow, white, and even bicolors. Individual plants can sometimes produce multiple colors of flowers.
• Leaves: The leaves are heart-shaped and have a lush, green appearance.
• Height: Generally, these plants can grow up to 2-3 feet tall.
• Habitat: They thrive in warm climates and are often used as ornamental plants in gardens.

Growing Conditions:

• Soil: Four o’clock flowers prefer well-drained soil but are quite adaptable to various soil types.
• Sunlight: They grow best in full sun to partial shade.
• Water: These plants need moderate watering. They are relatively drought-tolerant once established.
• Climate: Suitable for USDA hardiness zones 7-10.

Care Tips:

• Planting: Sow seeds directly in the garden after the last frost, or start indoors 6-8 weeks before the last frost date.
• Pruning: Deadhead spent flowers to encourage more blooms.
• Pests/Diseases: Generally pest-resistant but watch out for aphids and spider mites. Ensure good air circulation to prevent mildew.

Uses:

• Aesthetics: Their vibrant bloom colors make them excellent for border planting and containers.
• Traditional Uses: Some cultures use the plant for its medicinal properties, though it’s important to consult a healthcare provider before any such use.
• Attracting Wildlife: Their fragrant flowers attract hummingbirds and moths.

Fun Fact:

Mirabilis jalapa has a unique ability called “color changing” where the color of flowers on the same plant can change as they age and reseed, leading to a visually dynamic garden display.

These plants combine ease of care with striking visual appeal, making them a favorite among gardeners with various levels of experience.
