Four O'Clock (Mirabilis Jalapa Mix) - Four O'Clocks are a fast growing bush plant which are easy to grow from wild flower seed. They grow to about 36 inches with oval lance shaped leaves and trumpet shaped, fragrant flowers. Flowers may be shades of red, pink, yellow, white or striped. Mirabilis Jalapa is a wonderful addition to an evening garden. The blooms open in the afternoon, thus the common name "Four O'Clock." Even one flower opening releases a rich fragrance. They are a wonderful garden addition!
Four O'Clock plants thrive in all zones, blooming all summer long. Four O' Clocks thrive in ordinary soil in full sun or partial shade, sending up numerous volunteer seedlings every year (even in cold parts of the country.)
Mirabilis Jalapa wild flower seeds may be sown directly into the garden in the spring in warm areas. In other areas with a late spring, start the Four O'Clock flower seeds indoors about eight weeks before the final frost date for transplanting. Seedlings may be set in the garden at about the same time you would plant tomatoes. Allow about 12 inches between Four O' Clock 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.
Caution: Seeds are poisonous.
