Annual / Perennial Lemon Yellow Four O'Clock Seeds – Mirabilis jalapa – Soft Buttercup Trumpet Blooms with Red Anthers & Sweet Evening Fragrance.
🌸Sunny Lemon Trumpets with Glowing Red Centers for Your Evening Garden
Bring a touch of warm, sunny, buttery elegance to your evening garden with our Lemon Yellow Four O'Clock (Mirabilis jalapa) Seeds. Also known as the Marvel of Peru, this spectacular plant produces trumpet-shaped blooms in a bright, soft buttery lemon-yellow color. The delicate, slightly ruffled petals are beautifully accented by prominent, curving yellow stamens that bear striking, bright red-orange anthers, creating a beautiful, high-contrast focal point inside the bloom. This pure yellow variety offers a refined, classic look that brightens up any space from midsummer until the first frost.
But the magic doesn't stop at the visuals. True to its name, the blooms unfurl in the late afternoon (around 4 PM), releasing a delightful, sweet, and intoxicating perfume that fills the evening air, making it a perfect choice for patios, moon gardens, and evening landscapes. The tubular flowers are specifically adapted to attract hummingbirds and night-flying sphinx moths. In warm US zones, it returns year after year from underground tubers; in cooler zones, it thrives as a fast-growing annual or a treasured container plant. Heat-loving, drought-tolerant, and endlessly charming, this lemon yellow marvel is an absolute must-have for any cottage garden, evening landscape, or pollinator garden!
🌱How to Plant & Grow
-
Light Requirements: Full sun (6–8+ hours of direct sun per day is essential for vigorous growth and profuse blooming). Tolerates very light shade but will bloom less intensely.
-
Soil Type: Well-draining, average to fertile soil. Tolerates poor, sandy, or gravelly soils perfectly. Avoid heavy, waterlogged clay.
- Germination Time: 7–21 days at 65–75°F (18–24°C). Seeds have a thick, hard seed coat and require soaking for best results.
- Days to Maturity: 80–120 days from seed to first bloom.
-
Mature Height: 24–36 inches (2–3 feet). Spread: 24–36 inches (bushy mounding habit).
📏Spacing & Seeding Instructions
-
Plant Spacing: Space plants 18 to 24 inches apart.
-
Seeding Density (Per Square Foot): For mass planting, sow 1–2 seeds per square foot.
-
Sowing Depth: Sow seeds ½ inch deep. Cover firmly with soil. They do not require light to germinate.

Important Note: Four O'Clocks are frost-tender. Do not plant outdoors until the soil temperature has consistently reached at least 65°F (18°C) and all danger of frost has completely passed. In cooler zones, start seeds indoors 4-6 weeks before the last fros.
🧑🌾 Step-by-Step Planting Instructions
Start Indoors (Recommended for cooler zones for earlier blooms):
- After soaking/nicking seeds, fill biodegradable peat pots or seed trays with moist, well-draining seed-starting mix.
- Sow seeds ½ inch deep. Cover gently with soil and press down firmly.
- Place the tray in a warm area (65–75°F) with bright, indirect light. Keep the soil evenly moist.
- Seedlings emerge in 7–21 days. Provide strong, direct sunlight immediately to prevent leggy growth.
- After 6–8 weeks, when the seedlings have several sets of true leaves, gradually harden them off outdoors over 5–7 days before transplanting them into the garden.
Direct Sow (The easiest method for Zones 7–11):
- Wait until the soil is warm and all frost danger has passed.
- Prepare a well-drained bed in full sun. Remove all weeds and loosen the soil deeply.
- After soaking/nicking seeds, sow them ½ inch deep, spacing seeds 6–8 inches apart in rows.
- Water gently with a fine mist spray to avoid washing the seeds away. Keep the soil consistently moist until germination.
- Once seedlings are 4–6 inches tall, thin them out, leaving the strongest plants spaced 18–24 inches apart.
Ongoing Care:
- Watering: Water regularly during dry spells, especially when plants are young and during the blooming period. Once mature, they are exceptionally drought-tolerant. Water deeply at the base.
- Fertilizing: Do not over-fertilize. A light application of balanced, slow-release fertilizer at planting time is sufficient. Too much nitrogen will encourage lush foliage at the expense of flowers.
- Deadheading: While not strictly necessary, removing spent blooms will keep the plant looking tidy and encourage continuous blooming.
- Overwintering (For Cooler Zones): In cooler zones, you can dig up the underground tubers after the first frost, dry them, and store them in a cool, dry, frost-free place (like a basement) to replant next spring. Alternatively, let the plant die back, collect the large black seeds, and resow next year.
- Overwintering (For Warm Zones): In Zones 8–11, simply cut the dead stalks back to the ground after frost. The plant will naturally re-emerge from the underground tubers in the spring.
