How to grow
How To Grow Four O'Clock From Seed: Mirabilis Jalapa flower seeds may be sown directly into the garden in the spring in warm areas. In other areas with a late spring, start the flower seeds indoors about eight weeks before the final frost date for transplanting.
Four O'Clocks may be set in the garden at about the same time you would plant tomatoes. Allow about 12 inches between the plants. Mirabilis roots are tuberous and can be divided in early spring. Some gardeners will store the tubers indoors over the winter and then plant again in the spring.
