How to Grow Broken Colors Four O’Clock Seeds (Mirabilis jalapa):
Broken Colors Four O’Clocks are fast-growing warm-season annuals known for their multicolored, streaked blooms that open late afternoon. Direct sow outdoors after all danger of frost has passed and soil is warm; they don’t like cold soil. You can also start indoors 4–6 weeks early in biodegradable pots and transplant gently. Sow seeds about 1–1.5 cm (½ in) deep in well-drained soil. Choose a spot with full sun to light shade—full sun gives the best flowering. Space plants 30–45 cm (12–18 in) apart. Keep soil lightly moist until germination, which usually takes 7–14 days in warm conditions.
How to Care for Broken Colors Four O’Clocks:
Water regularly during establishment, then moderately—four o’clocks are drought tolerant once established and prefer soil to dry slightly between waterings. Overwatering leads to floppy growth. Fertilizer needs are low; a bit of compost at planting or a light balanced feed once mid-season is plenty. Pinch young plants to encourage bushier growth and more flowers. Blooms open in late afternoon and evening, attracting pollinators and adding fragrance to the garden. Deadheading isn’t required, but removing seed pods will reduce self-seeding if you want control. In warm climates, plants may form tuberous roots and come back the next year. Watch for aphids or leaf spots in humid weather; good airflow and watering at soil level help prevent issues.
