Description




Our high-quality 4 oclock seeds deliver reliable germination rate and vigorous clumping growth habit. Botanically named Mirabilis jalapa, four o'clock flower is a unique ornamental plant famous for its trumpet-shaped blossoms that stay closed during hot daytime and fully unfurl in late afternoon and evening, releasing sweet strong fragrance to attract nocturnal pollinators.
It boasts outstanding heat resistance and drought tolerance, thriving well under full sun in hot summer weather. Blooming repeatedly from early summer until frost, this multi-color flowering plant is widely used for garden border edging, roadside mass greening, backyard natural landscaping and large area decorative bedding. 4 oclock adapts to most ordinary well-drained soil with no strict fertilizer demands. Once established, it only needs occasional watering during extreme dry spells, perfectly fitting low-effort landscape projects and beginner gardening.

Planting Instructions

  1. Soil Preparation: Use loose, well-drained ordinary garden soil, poor soil is acceptable, avoid long-term waterlogged ground.
  2. Sowing Method: Soak hard seeds in warm water for 12 hours to boost germination, bury seeds 1cm deep into loosened soil and cover properly.
  3. Germination Condition: Keep soil slightly moist, maintain temperature 18–28°C, seeds sprout within 7–14 days.
  4. Seedling Care: Thin dense seedlings to reserve enough growing space; sufficient sunlight prevents leggy weak growth.
