GROWING AND SAVING SEED OF FOUR O'CLOCKS
Latin name Mirabilis jalapa is a frost-tender, herbaceous perennial often grown as an annual in the north. The dainty flowers will close during the heat of the day and open around 4 p.m., hence the name! The blooms attract beneficial insects, moths, and hummingbirds. Plant this fragrant night bloomer alongside moonflowers for a stunning evening display.
Native to the dry, tropical regions of Central and South America. Cultivated by the ancient Aztecs as a medicinal and ornamental plant. The flowers have been used to render a crimson-colored food dye. Be aware that the seeds are considered poisonous. Members of the Kayapo tribe in Brazil pulverize dried flowers into a powder, which they sniff to treat headaches.
