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

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

White Four O'Clock is suitable for cottage-style flower gardens, white-themed ornamental borders, evening gardens, patio planting areas, and outdoor container displays. Its white flowers provide a soft contrast against green foliage and complement informal garden arrangements.

Mirabilis jalapa is native to Mexico and Central America, with its accepted native range extending from Mexico to Nicaragua. Although the species is commonly called Marvel of Peru, the Royal Botanic Gardens, Kew, identifies Mexico to Nicaragua as its accepted native distribution.

The white-flowering form of Four O'Clock is especially interesting for gardeners who prefer delicate, light-colored flowers. Its trumpet-shaped blooms can create an attractive display during the late afternoon, evening, and early nighttime hours.

One of the plant's most recognizable characteristics is its unusual flowering schedule. Unlike many garden flowers that open primarily during the morning, Four O'Clock flowers commonly begin opening as daylight decreases. Individual blossoms may remain open during the evening and close or decline by the following morning.

The flowers have a narrow tubular base and a broad, flared opening. Their white coloration produces a clean ornamental appearance, particularly when displayed among green foliage or alongside other flowering plants.

The species may also produce a pleasant fragrance during the evening. This characteristic makes White Four O'Clock an interesting choice for managed evening gardens where flowers can be observed later in the day.

Four O'Clock develops broad green leaves that are generally ovate to somewhat heart-shaped, with pointed tips and smooth margins. These leaves grow in opposite pairs along branching stems, creating a lush background for the white blossoms.

The plant generally develops a rounded, bushy growth habit. Mature specimens commonly reach approximately 45–120 cm (18–48 inches) in height, depending on climate, sunlight, soil characteristics, and growing conditions.

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

As plants mature, they develop thickened underground storage roots. These tuberous structures may support regrowth during subsequent seasons where winter temperatures remain favorable.

Following flowering, White Four O'Clock produces distinctive dark, ribbed seed-bearing fruits. These structures mature to black or dark brown and may fall naturally into the surrounding soil.

Under suitable conditions, fallen seeds may germinate and produce additional plants. Removing mature fruits can help reduce unwanted self-seeding in managed ornamental garden beds.

White Four O'Clock generally grows well in full sun, although partial shade is tolerated. It prefers reasonably fertile, well-drained soil and moderate watering during establishment.

North Carolina State University Extension describes Mirabilis jalapa as a branching ornamental perennial that can also be grown as an annual, recommending full sun, suitable soil moisture, and optional overnight seed soaking to support propagation.

Foliage and Appearance

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

The leaves are generally ovate to somewhat heart-shaped, with pointed tips.

Their margins are typically smooth rather than strongly toothed.

The foliage develops in opposite pairs along the stems.

Young plants initially produce small green leaves before establishing a fuller branching structure.

As the growing season progresses, additional foliage develops along the expanding stems.

The leaves typically have visible veins and a relatively smooth surface.

The green foliage provides an attractive contrast to the plant's white trumpet-shaped blossoms.

Stem and Branch Characteristics

Mirabilis jalapa develops upright, branching herbaceous stems.

The stems are generally green, although reddish or purplish tones may develop under certain conditions.

As plants mature, additional branches form, creating a rounded or spreading growth habit.

The stems support opposite leaves and clusters of developing flower buds.

Mature specimens may develop numerous flowering branches during favorable growing conditions.

In suitable warm climates, established underground roots may support new above-ground growth during successive growing seasons.

Flower Characteristics

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

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

The colorful or showy portion of the blossom is formed by a petal-like perianth rather than separate conventional petals.

The white-flowering selection is identified by its white blossoms, although minor natural variation in shade or appearance may occur.

Individual flowers commonly measure approximately 2.5–3.5 cm across, depending on genetics and growing conditions.

Flower buds develop near the ends of the branching stems.

The blossoms typically begin opening during the late afternoon or early evening.

Cloudy weather may encourage earlier flowering.

Flowers may remain open into the evening and nighttime hours.

The exact opening time varies according to temperature, light exposure, and environmental conditions.

The species is not guaranteed to open its flowers precisely at 4:00 PM.

Kew's botanical descriptions document white flowers as one of the recognized color forms of Mirabilis jalapa and describe its fragrant, late-afternoon-opening blossoms.

Seed and Fruit Characteristics

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

These structures are generally rounded to oval.

Mature fruits commonly appear black or very dark brown.

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

Botanically, these structures are called anthocarps.

Each mature anthocarp contains a seed enclosed within persistent floral tissue.

Mature fruits may detach naturally and fall into nearby garden soil.

Under favorable conditions, fallen seeds may germinate and establish additional plants.

Removing mature fruits can help prevent excessive self-seeding.

Root Characteristics

White Four O'Clock develops thickened underground storage roots as the plant matures.

These tuberous structures store resources that may support new growth.

In climates with sufficiently mild winters, established plants can survive beyond a single growing season.

The underground structures may produce new shoots when favorable conditions return.

In regions experiencing severe freezing temperatures, the roots may be damaged during winter.

Mature roots can sometimes be lifted and stored in protected conditions for replanting.

The tuberous roots are not edible 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 generally ranges from approximately 30–60 cm (12–24 inches), although vigorous specimens may grow wider.

The plant develops multiple leafy stems that create a rounded appearance.

The white blossoms develop among the green foliage and provide attractive seasonal contrast.

Its growth habit makes it suitable for garden borders, decorative planting beds, and spacious outdoor containers.

Seasonal Development

White Four O'Clock seeds germinate when sufficient warmth and soil moisture are available.

Young seedlings establish roots and begin producing opposite green leaves.

As growth progresses, additional branches develop.

Flower buds form near the ends of mature shoots.

White blossoms typically open during late afternoon and evening.

Following flowering, dark ribbed seed-bearing fruits develop and mature.

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

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

In colder climates, Four O'Clock is commonly cultivated as an annual.

Pollinator and Botanical Interest

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

Their late-day flowering habit makes the plant particularly interesting for observing evening pollination activity.

North Carolina State University Extension identifies moths and hummingbirds among the flower visitors associated with Mirabilis jalapa.
