Four O'Clock Flower Seeds,Mirabilis jalapa,Marvel of Peru for Garden Planting

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

Four O'Clock is a traditional garden favorite for cottage-style flower beds, ornamental borders, patio gardens, evening landscapes, and outdoor containers. Its vibrant flowers and distinctive flowering schedule provide seasonal interest, particularly in gardens enjoyed during the later hours of the day.

Mirabilis jalapa is native to Mexico and Central America, with its accepted native range extending from Mexico to Nicaragua according to the Royal Botanic Gardens, Kew. The species is now widely cultivated in suitable warm climates and has become naturalized in many regions.

One of the most recognizable characteristics of Four O'Clock is the timing of its flowers. Unlike many ornamental plants that open their blossoms during the morning, Four O'Clock commonly begins opening its flowers during the late afternoon. In suitable conditions, flowers may remain open into the evening and night.

The plant produces colorful, funnel-shaped blossoms in a range of possible shades, including pink, red, yellow, white, magenta, and purple. Some varieties may produce striped, spotted, or multicolored flowers. Individual plants can sometimes display blossoms with different colors or patterns.

The exact flower colors depend on the variety and seed genetics. Because a specific color selection has not been identified in the supplied product information, no particular flower color or mixed-color combination is guaranteed.

Four O'Clock develops broad green leaves that are generally oval to heart-shaped, with pointed tips and smooth margins. The leaves occur in opposite pairs along branching stems, giving the plant a lush, rounded appearance.

The species typically develops a bushy growth habit with multiple stems and flowering branches. Mature plants commonly reach approximately 45–120 cm (18–48 inches) in height, depending on climate, soil conditions, and growing season.

Mirabilis jalapa is a tender perennial that may return during successive growing seasons in suitable warm climates. In regions experiencing freezing winter conditions, it is commonly cultivated as an annual.

As plants mature, they develop thickened underground storage roots. These tuberous roots can support seasonal regrowth where winter conditions are sufficiently mild.

Four O'Clock blossoms may produce a noticeable fragrance during the evening. Their late-opening flowers may attract moths and other flower-visiting animals, making the species interesting for ornamental evening gardens.

Following flowering, the plant produces distinctive dark, ribbed seed-bearing fruits. These mature structures can fall into nearby soil and may produce volunteer seedlings under favorable conditions.

Four O'Clock generally performs well in full sun, although partial shade is tolerated. The plant prefers reasonably fertile, well-drained soil and moderate moisture during establishment. Established specimens can tolerate occasional dry conditions.

University of Wisconsin–Madison Extension describes Four O'Clock as a traditional tender perennial frequently grown as an annual in temperate climates, with a branching, shrub-like habit and flowers that open late in the day.

Foliage and Appearance

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

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

They develop in opposite pairs along the stems.

Young plants initially produce small green leaves before forming a more extensive branching structure.

As plants mature, the foliage becomes fuller and supports numerous flowering shoots.

The leaf surfaces are usually relatively smooth, with visible veins extending through the blades.

The broad green leaves create an attractive background for the colorful blossoms.

Stem and Branch Characteristics

Mirabilis jalapa develops upright, branching herbaceous stems.

The stems are generally green but may display reddish or purplish tones.

Additional branches form as the plant matures, creating a rounded or spreading appearance.

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

Mature plants may produce numerous flowering branches during suitable growing conditions.

In warm climates, new above-ground stems may develop from established underground roots during subsequent seasons.

Flower Characteristics

Four O'Clock produces colorful funnel-shaped or trumpet-shaped flowers.

The showy portion of each flower consists of a petal-like perianth.

The flowers generally have a long, narrow tube with a broad, flared opening.

Possible flower colors include pink, magenta, red, yellow, white, purple, and combinations of these shades.

Some plants may produce striped, spotted, or variegated flowers.

Individual blossoms commonly measure approximately 2.5–5 cm across, depending on the plant and variety.

Flowers develop in small clusters near the ends of branches.

The blossoms generally open during late afternoon or early evening.

Flower opening is influenced by light, temperature, and weather, so individual flowers are not guaranteed to open precisely at 4:00 PM.

The Royal Botanic Gardens, Kew, describes the flowers as fragrant and late-opening, with several possible colors, including white, pink, red, and yellow.

Seed and Fruit Characteristics

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

These structures are generally rounded to oval.

The mature fruits commonly appear black or very dark brown.

Their surfaces have prominent ribs and may be slightly rough or wrinkled.

Botanically, the seed-bearing structure is an anthocarp, a fruit enclosed by persistent floral tissue.

Mature anthocarps may fall naturally into the soil.

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

Because Four O'Clock may self-seed readily, mature fruits should be monitored where garden spreading is undesirable.

Root Characteristics

Four O'Clock develops thickened, tuberous underground roots.

These structures store resources that may support perennial regrowth.

In suitable frost-free climates, established plants can survive beyond a single growing season.

In colder climates, freezing temperatures may damage underground structures.

Mature tuberous roots may be lifted and stored in protected conditions for replanting when warm weather returns.

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

Growth Habit

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

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

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

The plant develops a rounded appearance with multiple leafy branches.

Its relatively full growth habit makes it suitable for mixed flower borders and large containers.

Seasonal Development

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

Young seedlings establish roots and begin producing opposite green leaves.

As plants mature, additional stems and branches develop.

Flower buds form near the upper portions of mature branches.

Colorful blossoms open during late afternoon and evening.

Following flowering, dark ribbed fruits develop.

Established plants may continue flowering during suitable warm weather.

In frost-free climates, mature plants may return during subsequent growing seasons.

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

Pollinator and Botanical Interest

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

The species is particularly interesting because its flowers often open when many daytime-flowering ornamentals are closing.

Its colorful perianth, variable flower patterns, tuberous roots, and distinctive dark fruits provide additional botanical interest.
