Our premium yellow four o clock seeds feature high germination rate and robust clumping growth. Botanically known as Mirabilis jalapa, this special single-color variety bears vivid pure yellow trumpet-shaped blooms. The flowers remain tightly closed under strong daytime sunshine and fully open in late afternoon and evening, emitting a pleasant sweet fragrance to attract night pollinators.
This yellow four o clock plant has exceptional heat resistance and drought tolerance, performing vigorously in hot summer climates. It blooms continuously from early summer all the way to the first autumn frost. Ideal applications include garden border edging, roadside slope greening, backyard natural landscaping and large-area monochrome bedding layout. It is highly adaptable to most loose, well-drained ordinary soils without high fertilizer requirements. After root system establishment, only occasional supplemental watering during extreme drought is needed, making it a perfect low-maintenance choice for landscape engineering and novice gardeners.
