Growing Tips & Guides
Organic White Four O'Clock (Mirabilis jalapa), also commonly known as White Marvel of Peru, is an attractive ornamental flowering plant belonging to the Nyctaginaceae family. This distinctive white-flowering selection is recognized for its elegant trumpet-shaped blossoms, lush green foliage, bushy branching growth habit, and unusual tendency to open its flowers during the late afternoon or early evening.
White Four O'Clock is particularly suitable for ornamental flower gardens, white-themed flower borders, cottage-style landscapes, moon gardens, patio planting areas, and outdoor containers. Its delicate white blossoms create an attractive contrast against broad green leaves and complement gardens designed with soft, natural colors.
Mirabilis jalapa is native to Mexico and Central America, with a native distribution extending from Mexico to Nicaragua. Although the species is widely known as Marvel of Peru, it has been cultivated and introduced into many regions beyond its original geographical range.
One of the most distinctive characteristics of White Four O'Clock is its late-day flowering behavior. The blossoms commonly begin opening during the late afternoon, often remaining open through the evening and part of the night. Cloudy conditions may also encourage flowers to open earlier in the day.
The flowers are typically white, with a narrow tubular base and a broad, flared opening. Their elegant shape creates a soft ornamental display, especially in evening gardens where pale flowers remain visually noticeable as daylight fades.
White Four O'Clock flowers may release a pleasant fragrance during late afternoon and evening. This characteristic makes them interesting for gardeners who enjoy flowering plants around patios, pathways, and outdoor seating areas.
The plant develops broad green leaves that are generally ovate to 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.
White Four O'Clock generally develops a bushy, rounded growth habit. Multiple stems and branches emerge as the plant matures, supporting clusters of flower buds and open blossoms throughout the warm growing season.
Mature plants commonly reach approximately 45–120 cm (18–48 inches) in height, depending on genetics, growing conditions, available sunlight, and climate. Their branching structure makes them suitable for managed ornamental beds and spacious outdoor containers.
Mirabilis jalapa is a tender perennial in suitable warm climates. In regions experiencing freezing winter temperatures, it is frequently cultivated as an annual flowering plant.
As plants mature, they develop thickened underground storage roots. These tuberous structures can support new growth during subsequent growing seasons where winter conditions remain sufficiently mild.
Following flowering, White Four O'Clock produces distinctive dark, ribbed seed-bearing fruits. These structures mature to black or very dark brown and may fall naturally into surrounding garden soil.
Under favorable conditions, fallen seeds may germinate and establish volunteer plants. Removing mature fruits can help prevent unwanted self-seeding in managed garden beds.
White Four O'Clock generally performs best in full sunlight, although partial shade is tolerated. It prefers reasonably fertile, well-drained soil and moderate watering during establishment. Established plants can tolerate occasional dry periods.

Additional moisture may be necessary during prolonged hot or dry weather.
Avoid continuously waterlogged soil.
Temperature and Climate
White Four O'Clock is a warm-season flowering plant.
Seeds generally germinate more readily when soil temperatures are warm.
The species can grow as a perennial in sufficiently mild climates.
In areas experiencing freezing winters, it is commonly grown as an annual.
Established underground storage roots may survive mild winters but can be damaged by severe frost.
Garden Placement
Choose a sunny ornamental flower border, white-themed garden, moon garden, cottage-style planting bed, patio garden, or spacious outdoor container.
Plant where the late-afternoon and evening flowers can be appreciated.
Allow adequate space for branching growth.
Because Four O'Clock may self-seed, select a location where unwanted volunteer seedlings can be managed.
How to Grow White Four O'Clock from Organic Seeds
-
Choose the Sowing Season: Sow during spring after frost danger has passed, or during another suitable warm growing season.
-
Select a Sunny Location: Choose full sun or light partial shade.
-
Prepare the Garden Soil: Loosen the upper soil layer and remove large debris.
-
Improve Drainage: Ensure the planting area drains adequately.
-
Consider Indoor Seed Starting: Start seeds in containers before the outdoor planting season where necessary.
-
Choose Suitable Containers: Select clean seed trays or small pots with drainage holes.
-
Prepare the Growing Medium: Use a well-drained seed-starting mixture.
-
Moisten the Medium: Water gently before sowing.
-
Inspect the Seeds: Four O'Clock seeds have relatively firm outer coverings.
-
Consider Overnight Soaking: Soak the seeds in room-temperature water overnight to help soften their outer coverings.
-
Avoid Prolonged Soaking: Do not leave seeds submerged for excessive periods.
-
Sow at a Suitable Depth: Plant seeds approximately 1–1.5 cm (about ½ inch) deep.
-
Cover with Soil: Gently cover the seeds with fine growing medium.
-
Water Carefully: Moisten the soil without displacing the seeds.
-
Maintain Warm Conditions: Approximately 20–25°C (68–77°F) is a practical starting range for propagation.
-
Maintain Consistent Moisture: Keep the medium gently moist without prolonged saturation.
-
Monitor Germination: Seedlings may emerge within approximately 7–14 days under favorable conditions, although actual timing varies.
-
Provide Adequate Light: Place emerging seedlings in a bright growing location.
-
Observe True Leaf Development: Allow young seedlings to develop their first true leaves.
-
Thin Overcrowded Seedlings: Remove excess seedlings when necessary.
-
Support Root Establishment: Maintain moderate moisture while roots develop.
-
Transplant into Individual Pots: Move established seedlings when additional growing space is needed.
-
Acclimate Seedlings Outdoors: Gradually introduce indoor-grown seedlings to outdoor sunlight, wind, and temperature conditions.
-
Prepare the Final Garden Bed: Choose reasonably fertile, well-drained soil.
-
Allow Suitable Spacing: Position plants approximately 30–60 cm (12–24 inches) apart.
-
Transplant Carefully: Place seedlings at approximately the same depth as they grew in their containers.
-
Water After Planting: Provide moderate watering to support establishment.
-
Monitor Branching Growth: Observe the development of green foliage and flowering shoots.
-
Observe White Flowering: Look for white trumpet-shaped blossoms opening during late afternoon or evening.
-
Manage Seed Formation: Remove mature fruits where unwanted self-seeding is a concern.

Important Growing Information
White Four O'Clock (Mirabilis jalapa) is an ornamental flowering selection recognized for its elegant white trumpet-shaped blossoms, late-afternoon flowering behavior, broad green foliage, and bushy branching habit. These characteristics make it suitable for white-themed flower borders, moon gardens, cottage-style planting areas, and ornamental container displays.
Botanical identification: Mirabilis jalapa belongs to the Nyctaginaceae family. Its distinguishing features include opposite leaves, branching stems, tubular flowers, thickened storage roots, and dark ribbed seed-bearing fruits.
Common names: The white-flowering selection is commonly described as White Four O'Clock or White Marvel of Peru. These names identify the intended flower color and distinguish it from other colored forms of the species.
Native distribution: Mirabilis jalapa is native from Mexico to Nicaragua. The species has been widely cultivated in other regions, where it may also establish naturalized populations.
White flower characteristics: This seed packet is identified as a white-flowering selection. The flowers typically have a narrow tubular base and a broad, flared white opening. Seed-grown plants can exhibit some variation depending on genetic characteristics and the seed line.
Flower opening behavior: White Four O'Clock blossoms generally open during late afternoon or early evening. Cloudy conditions may encourage earlier opening. Flower opening is not guaranteed to occur at exactly 4:00 PM.
Flower structure: Four O'Clock flowers consist of a tubular, petal-like perianth rather than separate conventional petals. The white-flowering form creates a soft contrast against its broad green foliage.
Evening fragrance: Many Four O'Clock plants produce fragrant flowers during evening hours. Fragrance intensity may vary according to genetics, temperature, and environmental conditions.
Perennial growth characteristics: White Four O'Clock is a tender perennial that develops thickened underground storage roots. These structures may support regrowth during successive seasons in sufficiently warm climates.
Annual cultivation: In frost-prone regions, Four O'Clock is commonly cultivated as an annual. Mature storage roots may be lifted before freezing weather and stored under protected conditions.
Seed germination: Four O'Clock seeds have relatively firm outer coverings. Overnight soaking may help soften these coverings and encourage faster germination. Maintain warm temperatures and gentle soil moisture during propagation.
Sunlight requirements: White Four O'Clock generally performs best in full sun but tolerates partial shade. Adequate sunlight supports healthy branching and flower production.
Soil and moisture requirements: The plant grows in a range of garden soils but generally prefers well-drained, reasonably fertile conditions. Consistent moisture supports early growth, while mature plants can tolerate occasional dry periods.
Mature plant size: Plants commonly reach approximately 45–120 cm in height and 30–60 cm in spread. Actual dimensions vary according to plant genetics, climate, sunlight, soil conditions, and moisture.
Tuberous root development: Established plants produce thick underground storage roots. These structures can support new seasonal growth where winter conditions remain suitable.
Moon garden suitability: White Four O'Clock is particularly attractive in moon gardens because its pale flowers generally open as daylight fades. The blossoms may be appreciated around paths, garden seating areas, and outdoor patios.
Pollinator observation: Flowers may attract moths and other visiting insects. Their late-opening habit makes the species interesting for observing afternoon and evening pollination activity.
Self-seeding and garden management: Mature plants may produce dark ribbed fruits that fall into surrounding soil. Volunteer seedlings can develop under suitable conditions. Remove mature fruits and unwanted seedlings when necessary to maintain the planting area.
Plant safety and handling precautions: Seeds and tuberous roots may cause adverse effects if ingested, including gastrointestinal discomfort. Handling roots can irritate sensitive skin. Wear gloves when working with mature roots and keep seeds and plant material away from children and pets.
Regional planting considerations: Four O'Clock has become naturalized outside its original native distribution. Gardeners should check local planting guidance and prevent unwanted establishment in unmanaged natural environments.
Seed packet quantity: The original supplied product information specifies 7 seeds per packet. Germination and the number of established plants depend on seed viability, soil temperature, moisture, and growing conditions.
Organic designation: These seeds are described as organic in the supplied product information. Specific certification documentation has not been independently verified.
Intended use: These seeds are intended for ornamental gardening and botanical cultivation. Planting seeds, tuberous roots, and other plant parts are not intended for direct consumption. No medicinal, therapeutic, dietary supplement, or pest-control claims are made.
Natural variation: Mature height, flower shape, flower coloration, blooming time, branching habit, fragrance, fruit production, and perennial survival may vary according to genetics and environmental conditions.
This listing describes the white-flowering selection of Mirabilis jalapa for ornamental flower gardens, white-themed borders, evening displays, and outdoor container cultivation, with attention to its self-seeding characteristics and plant safety.
