Complete Plant Information
Overview
The Marvel of Peru, scientifically known as Mirabilis jalapa, is an old garden favorite valued for its fast growth and vibrant, colorful blooms that appear in the late afternoon. This plant is easily recognized by its unique blooming schedule, often opening its fragrant, funnel-shaped flowers around four o’clock in the afternoon and closing them by morning. It brings an exotic touch wherever it is planted, offering a medley of pink, red, yellow, and white flowers sometimes appearing mottled on a single Mirabilis jalapa specimen.
As a tuberous-rooted tender perennial, it thrives across USDA Zones 9 through 11, but gardeners elsewhere treat it as a rewarding warm-season annual. Its low maintenance requirements and ability to tolerate various soil conditions, including wet soil, make the Marvel of Peru an accessible and reliable choice for adding height and fragrance to summer displays. Established roots ensure robust flowering, which is a key reason for overwintering the tubers in colder regions.
This species fits beautifully into mixed borders, containers, or as a temporary hedge due to its bushy habit and rapid maturity. While the flowers attract hummingbirds, gardeners must use caution as all parts of the Mirabilis jalapa plant are poisonous if ingested.

How to Grow
For the best results with Mirabilis jalapa, sow seeds directly into the garden well after the danger of the last frost has passed. Alternatively, you can get a head start by beginning seeds indoors about six to eight weeks prior to transplanting. Set out seedlings, purchased plants, or overwintered tubers only after the soil has warmed sufficiently following the last frost date. This plant adapts well to average, consistently moist, well-drained soils but tolerates a surprisingly wide range of soil types.
The Marvel of Peru requires a medium amount of water to maintain consistent soil moisture throughout the growing season. While it thrives in full sun, it also performs adequately with partial shade, though this may slightly reduce the profusion of blooms. Because it is generally a low-maintenance plant, significant fertilization is usually unnecessary if the soil is reasonably fertile.
If you garden outside of Zones 9-11, treating the Marvel of Peru as an annual is common. However, to ensure superior flowering the subsequent year, the tuberous roots should be carefully dug up in the fall before the first hard freeze. Store the tubers overwinter in a cool, dry location, packed in a barely moist medium like peat moss or sand, safe from frost exposure in a basement or frost-free garage.
Landscape Uses
The bushy, upright structure of the Mirabilis jalapa makes it highly versatile in landscape design. They look attractive planted in groups to create broad sweeps of color, or they can be used as striking single specimens within a mixed border setting. For seasonal impact, they function well as an annual hedge, a usage that was particularly popular during the Victorian era for outlining pathways or garden rooms.
Because they are robust and tolerate wet soil, these plants fit perfectly into rain gardens where moisture levels can fluctuate. Furthermore, the vibrant colors and evening fragrance make them excellent candidates for patio containers. Plan plantings near seating areas to ensure you can enjoy the afternoon fragrance as the flowers unfurl.

Wildlife Benefits
The structure and timing of the Mirabilis jalapa flower make it particularly appealing to specific pollinators. The tubular shape of the blossoms is perfectly suited for the long tongues of hummingbirds, which are often seen visiting the flowers during their afternoon opening period. Planting clusters of these vibrant flowers can create reliable nectar sources throughout the humid summer months.
Companion Planting
Due to its medium water requirements and tolerance for a range of soils, the Marvel of Peru pairs well with other summer-blooming annuals that enjoy similar conditions, such as Zinnias or Cannas, creating rich textures in a mixed border. Placing Mirabilis jalapa near structural, heat-tolerant perennials like ornamental grasses or Sedum allows the upright stems to fill in gaps as the season progresses. Ensure companions do not create too much dense shade, as the plant prefers high light levels.
