What Makes Survival Garden Seeds Different - non-GMO heirloom seeds

Formula Mix Four O’Clock Seeds (Mirabilis jalapa) produce a lively display of trumpet-shaped flowers that open in the late afternoon and continue blooming through summer. This classic garden favorite is known for its evening fragrance, fast growth, and wide range of cheerful colors.

Plants form bushy, quick-growing clumps reaching 12–36 inches tall. The Formula Mix delivers a blend of pink, red, yellow, and white flowers, often with varied patterns, creating a vibrant and unpredictable garden show. Four O’Clocks are tender perennials in warm climates and are commonly grown as annuals in cooler regions.
