Four O'Clock Flower Seeds ,Mirabilis jalapa,Marvel of Peru for Ornamental Gardens

Four O'Clock (Mirabilis jalapa), commonly known as Marvel of Peru, is an attractive flowering plant belonging to the Nyctaginaceae family, also called the four-o'clock family. This distinctive ornamental species is recognized for its colorful trumpet-shaped flowers, lush green foliage, bushy growth habit, and unusual tendency to open its blossoms during the late afternoon or early evening.

Four O'Clock flowers are popular in cottage-style gardens, ornamental flower borders, patio landscapes, evening gardens, and outdoor containers. Their colorful blossoms and distinctive flowering schedule make them especially interesting for gardeners who enjoy observing flowers during the later hours of the day.

Mirabilis jalapa is native to a region extending from Mexico to Nicaragua. Although commonly called Marvel of Peru, its accepted native distribution, according to the Royal Botanic Gardens, Kew, is Mexico to Nicaragua. The species has been widely introduced and cultivated in tropical, subtropical, and other suitable growing regions.

One of the most distinctive features of Four O'Clock is its late-afternoon flowering habit. Individual blossoms commonly open as daylight begins to fade and may remain open into the night. Cloudy weather can also encourage flowers to open earlier in the day.

The plant produces trumpet-shaped flowers in several possible colors, including pink, red, yellow, white, and purple. Some varieties may display striped, speckled, or multicolored patterns. Different flower colors can sometimes occur on the same plant, although the exact colors cannot be determined from the supplied seed information.

Four O'Clock develops a bushy, branching structure with numerous green leaves. The foliage is generally oval to heart-shaped, with pointed tips and smooth margins. Opposite leaf pairs develop along the stems, creating an attractive leafy background for the colorful blossoms.

Mature plants commonly reach approximately 45–120 cm (18–48 inches) in height, depending on climate, soil conditions, and growing season. Their rounded, bushy growth habit makes them suitable for mixed ornamental borders and individual garden displays.

Mirabilis jalapa is a tender perennial in suitable warm climates but is frequently cultivated as an annual in regions experiencing freezing winter temperatures. Established plants develop thick, tuberous underground roots that can support regrowth when winter conditions permit.

The flowers may produce a pleasant fragrance during the late afternoon and evening. They can attract visiting moths and other flower-visiting animals, making Four O'Clock an interesting choice for managed evening pollinator gardens.

Following flowering, the plant produces dark, rounded, prominently ribbed seed-bearing fruits. These mature structures are commonly black and can be collected for future propagation once fully developed.

Four O'Clock generally prefers full sunlight, reasonably fertile, well-drained soil, and moderate watering during establishment. It can tolerate partial shade, although flowering performance may vary.

North Carolina State University Extension identifies Mirabilis jalapa as a flowering perennial that can also be grown annually, with good performance in full sun, tolerance of partial shade, and propagation through seeds or established tuberous roots.

Foliage and Appearance

Four O'Clock develops attractive green foliage consisting of broad, simple leaves.

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

Their margins are typically smooth, unlike the strongly toothed leaves of some ornamental garden species.

The leaves occur in opposite pairs along the stems.

Young plants initially produce small green leaves and gradually develop a fuller branching structure.

As the plant matures, the foliage becomes denser and supports numerous flowering branches.

The green leaves provide an attractive contrast to the colorful trumpet-shaped flowers.

Stem and Branch Characteristics

Mirabilis jalapa develops upright, branching herbaceous stems.

The stems are generally green, although some may develop reddish or purplish tones.

As plants mature, additional branches form from the main stems, creating a rounded or spreading appearance.

Multiple flowering branches may develop on a healthy plant.

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

In warm climates, mature plants may develop substantial above-ground growth during successive seasons.

Flower Characteristics

Four O'Clock produces distinctive funnel-shaped or trumpet-shaped blossoms.

The flowers have a narrow tubular base and a broadly flared opening.

The colorful portion of the flower is formed by the petal-like perianth rather than separate conventional petals.

The flowers commonly appear in shades of pink, red, yellow, white, purple, and combinations of these colors.

Some varieties may display streaks, spots, or differently colored sections.

Individual flowers generally measure approximately 2.5–5 cm across, with natural variation.

Flower buds develop in small clusters near the ends of branches.

Blossoms commonly open during late afternoon or early evening and may remain open through part of the night.

Their timing depends on daylight, temperature, humidity, and other environmental conditions; flowers do not necessarily open at exactly 4:00 PM.

Seed and Fruit Characteristics

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

The mature fruits are generally rounded to oval and appear black or very dark brown.

Their surfaces are visibly ribbed and may have a slightly rough texture.

These seed-bearing fruits are relatively large compared with the tiny seeds of many other ornamental flowering plants.

Mature fruits can drop naturally into the soil.

Under suitable conditions, fallen seeds may germinate and produce new plants.

Because Four O'Clock can self-seed readily, mature seed formation should be monitored where garden spread is a concern.

Root and Tuberous Growth Characteristics

Four O'Clock develops thickened underground roots as it matures.

These roots store resources that can support seasonal regrowth.

In climates without damaging winter freezes, established plants may return during subsequent growing seasons.

In colder regions, the roots may be damaged by freezing temperatures.

Gardeners sometimes lift and store mature tuberous roots during winter in frost-prone regions.

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

Growth Habit

Mirabilis jalapa typically develops a bushy, branching growth habit.

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

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

The plant generally develops numerous leafy branches, creating a rounded ornamental appearance.

Four O'Clock is suitable for garden borders and spacious containers where its mature size can be accommodated.

Seasonal Development

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

Young seedlings establish roots and develop opposite green leaves.

As temperatures remain favorable, stems elongate and produce additional branches.

Flower buds begin forming on mature flowering shoots.

Colorful blossoms open during late afternoon, evening, or suitable cloudy conditions.

Following pollination, dark seed-bearing fruits develop.

In frost-free climates, the established underground root system may support further seasonal growth.

In colder regions, the plant is commonly grown as a warm-season annual.

Pollinator and Botanical Interest

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

Their late-afternoon and nighttime flowering habit provides an interesting comparison with species that flower primarily during the day.

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

Its variable flower colors, tuberous roots, and dark ribbed fruits also make the species interesting for ornamental botanical collections.
