Organic White Four O'Clock ,Mirabilis jalapa Seeds for Flower Garden Growing

Organic White Four O'Clock (Mirabilis jalapa), also known as White Marvel of Peru, is an ornamental flowering plant belonging to the Nyctaginaceae family. This white-flowering selection is recognized for its elegant trumpet-shaped blossoms, lush green foliage, bushy growth habit, and distinctive tendency to open its flowers during the late afternoon or early evening.

White Four O'Clock is a suitable choice for flower gardens, white-themed ornamental borders, cottage-style planting beds, moon gardens, patio displays, and outdoor containers. Its pale blossoms create a soft contrast against green foliage and add seasonal interest to gardens enjoyed during the later hours of the day.

The species Mirabilis jalapa is native to Mexico and Central America, with its accepted native range extending from Mexico to Nicaragua. It is widely cultivated in warm regions throughout the world. Although the species is commonly called Marvel of Peru, that name does not accurately describe its accepted native distribution.

One of its most recognizable ornamental characteristics is its unusual flowering schedule. The blossoms generally begin opening in the late afternoon and can remain open into the evening or nighttime hours. Flowers may also open earlier during overcast conditions.

The white-flowering selection produces funnel-shaped blossoms with narrow tubular bases and flared openings. Their light coloration makes them particularly attractive in evening gardens, where pale flowers remain noticeable as daylight fades.

Four O'Clock flowers may release a pleasant fragrance during the evening. Their late-opening habit can also attract moths and other visiting animals, offering opportunities to observe pollinator activity later in the day.

The plant develops broad, smooth-edged green leaves that are generally ovate to somewhat heart-shaped. These leaves grow in opposite pairs along branching stems, creating a full, rounded appearance.

White Four O'Clock generally develops several leafy branches as it matures. Its bushy structure makes it appropriate for mixed flower borders and individual ornamental displays.

Mature plants commonly grow approximately 45–120 cm (18–48 inches) tall, although actual height depends on growing conditions, climate, and plant genetics.

Mirabilis jalapa is a tender perennial in suitable warm climates. In regions experiencing freezing winter temperatures, gardeners commonly grow it as a warm-season annual.

Established plants develop thickened underground storage roots that can support regrowth in climates where winter conditions are sufficiently mild.

After flowering, the plant produces dark, ribbed seed-bearing fruits. These fruits can fall into nearby garden soil and produce additional seedlings when growing conditions are favorable.

White Four O'Clock generally prefers full sun, although it tolerates partial shade. Reasonably fertile, well-drained soil and consistent moisture during establishment encourage healthy growth.

North Carolina State University Extension identifies Four O'Clock as a branching perennial that can also be grown as an annual. It recommends full sun, notes the plant's partial-shade tolerance, and describes propagation from seeds and division.

Foliage and Appearance

White Four O'Clock develops broad green leaves along its branching stems.

The leaves are generally ovate or somewhat heart-shaped, with pointed tips and smooth margins.

They occur in opposite pairs along the stems.

Young plants initially develop smaller green leaves before producing a more extensive branching structure.

As the plant matures, additional foliage forms along its stems.

The leaves have visible veins and provide an attractive background for the white flowers.

Stem and Branch Characteristics

Mirabilis jalapa develops upright, branching herbaceous stems.

The stems are usually green but may develop reddish or purplish coloration.

Additional branches form during the growing season, producing a rounded ornamental appearance.

The stems support opposite leaf pairs and clusters of developing flower buds.

In warm climates, established underground roots may support new shoots during subsequent growing seasons.

Flower Characteristics

White Four O'Clock produces white, funnel-shaped or trumpet-shaped flowers.

Each blossom has a narrow tubular base and a broad, flared opening.

The white, showy portion of the flower is a petal-like perianth rather than a conventional arrangement of separate petals.

Individual flowers commonly measure approximately 2.5–3.5 cm across at the opening, although size varies.

The flowers develop in small clusters near the ends of branching stems.

Flower buds generally open during the late afternoon or early evening.

Under suitable conditions, blossoms may remain open during the evening or part of the night.

Light exposure, temperature, and weather can influence the exact flowering schedule.

The plant's common name refers to its typical late-day flowering habit rather than a guaranteed opening time of precisely 4:00 PM.

Kew's botanical descriptions of Mirabilis jalapa recognize white as one of its flower colors and describe the species' late-afternoon-opening, fragrant flowers.

Seed and Fruit Characteristics

Following flowering, White Four O'Clock develops distinctive dark seed-bearing fruits.

The mature structures are generally rounded or oval and become black or very dark brown.

Their surfaces are prominently ribbed and can appear slightly rough or wrinkled.

Botanically, these structures are called anthocarps.

Each anthocarp contains a seed enclosed by persistent floral tissue.

Mature fruits may fall naturally into surrounding garden soil.

Under suitable conditions, they may produce volunteer seedlings.

Removing mature fruits can help prevent unwanted self-seeding.

Root Characteristics

White Four O'Clock develops thickened underground storage roots.

These tuberous structures become larger as plants mature.

They store resources that may support seasonal regrowth.

In sufficiently warm climates, established plants may survive beyond a single growing season.

In colder climates, freezing temperatures can damage the underground roots.

Gardeners may lift mature roots before severe freezing weather and store them under suitable protected conditions.

The roots are not edible garden tubers and should not be consumed.

Growth Habit

White Four O'Clock is a bushy, branching ornamental flowering plant.

Mature plants commonly reach approximately 45–120 cm (18–48 inches) in height.

Their spread often ranges from approximately 30–60 cm (12–24 inches), although vigorous plants may grow wider.

Multiple leafy stems create a rounded plant form.

The white flowers stand out against the broad green foliage.

Its growth habit makes it suitable for managed ornamental garden beds, flower borders, and spacious outdoor containers.

Seasonal Development

Seeds germinate when suitable warmth and soil moisture are available.

Young seedlings establish their roots and develop opposite green leaves.

Branching stems become more prominent as growth progresses.

Flower buds develop near the ends of mature shoots.

White flowers open during late afternoon or evening.

Following flowering, dark ribbed fruits develop and mature.

In favorable climates, flowering may continue over an extended warm growing season.

Established underground storage roots may support new growth during subsequent seasons.

In regions with freezing winters, the species is commonly grown as an annual.

Pollinator and Botanical Interest

White Four O'Clock flowers may attract moths and other flower-visiting animals.

Their late-afternoon flowering habit makes them particularly interesting for observing pollinator activity during evening hours.

North Carolina State University Extension identifies moths and hummingbirds as visitors to Mirabilis jalapa flowers.

The species also provides botanical interest through its tubular flowers, opposite leaves, tuberous roots, and distinctive ribbed fruits.
