Mirabilis Jalapa - Four O'Clock

Mirabilis jalapa is known as four o'clock and 'Marvel of Peru.' Cultivated by the Aztecs not only for ornamental but for medicinal purposes as well, this native to the tropical areas of South America is a beautiful addition in the garden. It comes in different shades of color ranging from white, yellow, light to deep pink and it comes in mixed colors or stripes.

Often grown as an annual, mirabilis jalapa grows up to 1 meter with fragrant blooms which makes these sun loving plants perfect on front yards or in containers by the porch which gives the opportunity to enjoy the flowers as these only blooms in the late afternoon and through the night, closing and never to open again when the morning arrives.

Knowing Mirabilis Jalapa by Mistake

With seeds I got online for another plant I wish to have for the heavenly scent I've known since childhood, I was excited to find seeds to purchase. Waiting almost to over a week is nothing to me as the price is all worth it. Delighted when the seeds finally arrived and there's a lot in one packet, I was thrilled to start three seeds specially when all three successfully sprouted. As the three seddlings continuously grow, I started doubting if the plants are really what I paid for but brushing the thought off my head. When the buds started developing with pinkish unopened petals, only then I found out that these are four o'clock. Although they may not be the seeds I paid for, having these growing in the garden is a wonderful addition for the flowering plants.

Growing Four O'Clock from Seeds with Photos

Growing four o'clock from seeds is easy. Start the seeds after last frost date or in the spring season in a well-drained soil. It isn't picky when it comes to soil but keep it moist for an abundance of scented blossoms. Mine was planted already summer season as that was when I purchased the seeds. This plant isn't only good being planted directly on the ground where it gets sunlight but it does well in pots and containers too.

Sown from seeds, young sprouts emerged from the soil within a week with roundish pair of baby leaves. The next pair of leaves are oval in shape that are pointy at the tip. These green leaves grow in pairs with veins visible on either side.

Four O' Clock Flowers

The flowers of four o'clock start as green buds often in a number of 4 or more at the tip that reaches up to 2 inches long as it grows. As the buds continuous to grow, the young petals turn from pure green to yellowish or pinkish. And as the blooming nears, the color of the unopened petals peek through at the tip giving you a hint of what color the flowers will be. Four o'clock flowers start to bloom late in the afternoon which is around four o'clock, which is how the plant got one of its common name - four o'clock. The flowers remain open throughout the night which attract moths as pollinators. These will only be open for the entire night and will be closed the following morning. The trumpet-shaped flowers that bloom from summer to fall are sweetly fragrant.

Fruit and Seed

As the flower dries out the following day and eventually falls off, a green fruit remains protected by the sepals with the tip visible (referring to the photo below). Mirabilis jalapa seeds are wrinkled and black with some having a shade of brown. As the seed fully matures, they fall off the mother plant when not collected.
