Marabell, scientifically known as Mirabilis jalapa, is a garden flower known for its unique blooming schedule and vibrant colors. Often called the Four O’Clock flower, its fragrant, trumpet-shaped blossoms unfurl in the late afternoon or early evening, remaining open through the night. This low-maintenance plant is a rewarding addition for gardeners seeking beauty and fragrance as daylight fades.
Understanding Marabell
Commonly known as Four O’Clock flower or Marvel of Peru, Mirabilis jalapa originates from tropical America, known for its distinctive blooming habit. The Latin genus name “Mirabilis” translates to “wonderful,” alluding to the remarkable colors of its flowers. This bushy, semi-woody perennial typically reaches 18 inches to 4 feet tall and spreads 12 to 24 inches wide. Its fragrant flowers come in various hues, including pink, white, yellow, red, and magenta, sometimes featuring stripes or multiple colors. The scent is most noticeable in the evening, attracting nocturnal pollinators. While a perennial in warmer climates (USDA Zones 9-11), it is frequently cultivated as an annual in cooler regions where frost occurs.
Cultivating Marabell
Marabell plants can be grown from seeds, either by direct sowing outdoors after the last frost or by starting them indoors. Soaking seeds overnight before planting can help promote germination, though it is not strictly necessary. For indoor starting, sow seeds ¼ inch deep in a seed-starting mix about six to eight weeks before the last frost, maintaining 70°F (21°C). Transplant outdoors once seedlings have true leaves and frost danger has passed.
Marabell thrives in full sun, ideally receiving at least six hours of direct sunlight daily, but it can also tolerate partial shade, particularly in hotter climates. It adapts to various soil types but thrives in well-drained, moist soil, tolerating drought once established. Regular watering benefits young plants, but avoid overwatering to prevent root rot. While Marabell is not a heavy feeder, a balanced, slow-release or all-purpose floral fertilizer applied monthly can promote vigorous growth and abundant blooms.
Marabell Maintenance and Uses
Once established, Marabell requires low maintenance and is resistant to most common pests. While typically trouble-free, aphids may occasionally pose a problem, particularly on indoor plants. They can be managed by hand or with treatments. It self-seeds vigorously, which can lead to spread if not managed. Deadheading, which involves removing spent blooms, is an optional practice that can encourage more flowers. Allowing some flowers to go to seed will facilitate self-seeding for future seasons.
Marabell is versatile in the landscape, suitable for borders, mixed beds, or containers. Its bushy habit and continuous summer-to-fall blooming make it suitable for annual hedges. Their evening fragrance and blooming schedule make them well-suited for night gardens, patios, or areas near seating. They also attract nocturnal pollinators like moths and hummingbirds, adding ecological value to the garden.
