It’s Time to Plant Four O’Clocks


Did you know there’s a plant named after a time of day?

A collage of different photos showing close ups of pink and yellow Four O'Clock Flowers.

And while you may recall the rather old-fashioned four o’clock (Mirabilis jalapa) from visits to Grandma’s house, the name of the plant isn’t a reflection of when Grandma eats dinner.

Instead, the name indicates the time of day when the plant’s trumpet-shaped flowers open.

The flowers open in late afternoon, in response to a temperature drop. Nocturnal moths and other nighttime pollinators are attracted to their nectar.

Pink "passalong" four o'clock flowers creating a ground cover in garden beds.

The flowers remain open throughout the night and into the morning, when temperatures rise and the flowers wilt.  Like daylilies, four o’clock flowers bloom just a single time, then wilt and eventually fall off the plant.

On cloudy days, the flowers open earlier and sometimes won’t close at all. Again, this is not due to a lack of light, but rather, to temperatures that are lower than usual.

Consider growing four o'clock, the shrubby nocturne that brightens up evening gardens |

Many gardeners find deadheading unnecessary because even the wilted blooms are attractive, and the plant blooms profusely with or without deadheading.

Let’s learn more about this shrubby, colorful perennial!

Share and Share Alike

As if “four o’clock” weren’t an interesting enough name, this plant also goes by “marvel of Peru,” a nod to its native South American habitat.

This flower has been cultivated for hundreds of years. In its heyday a couple of generations ago, it was a popular “passalong” plant in the southern United States, meaning neighbors and friends frequently shared the plant with each other.

Take a page from Grandma's book and plant lovely four o'clock plants in your garden:

Hardy and grown as a perennial in zones 7b-11, gardeners in other zones often grow these beauties as annuals. They will self-sow.

This bushy nocturne can grow to be one to four feet tall, and one to three feet wide. It is heat and drought tolerant, and is a favorite of hummingbirds, bees, and butterflies.

Enjoy vibrant evening blooms from four o'clock |

Wild critters know not to ingest the roots and seeds of this plant, because they are poisonous. If your pooch has a propensity for eating random yard objects, you may want to collect the dark, leathery, round seeds.

In the deep south, M. jalapa begins blooming in late spring, while northern gardeners will have to wait until mid-summer to catch a whiff of the highly fragrant blooms.

Color, Color, and More Color

If color is your thing, you’ve come to the right place.

Four o’clock flowers can be pink, red, magenta, lavender, yellow, or white.

Plant four o'clock to add a vintage touch to your landscape |

The flowers may be a solid hue, or they may have more than one color in a striped, splotchy, or spotted pattern.

You may see different combinations of shades and patterns on a single plant.

And to further brighten your days, the flowers of some varieties will change color as the plant matures.

Add vintage beauty to your landscape by planting four o'clocks:

So, you buy a lovely yellow plant at the garden store in May, and walk out one July evening (around the time Grandma’s cooking dinner) to discover you now have a plant with dark pink flowers!

That said, here are some varieties that, with luck, will remain true to color:

White Four o’Clock Seeds

Gardeners looking for a blaze of white might want to consider M. jalapa ‘Alba’, available from My Seedy Needs via Amazon.

Four o’Clock ‘Pink Trumpet’ Seeds

For a vibrant pink bloom, try ‘Pink Trumpet’ from Country Creek Acres, via Amazon.

Four O’Clock Bi-Color Mix Seeds

And if a kaleidoscope of patterned blooms is what you’re looking for, try this mixture from David’s Garden Seeds, available through Amazon.

Time to Plant

M. jalapa flowers best if it’s planted in full sun, but it will take some shade.

This plant prefers neutral to slightly acidic soil, and it is a heavy feeder, so make sure your soil is rich in organic material.

Four o'clock is an attractive addition to planters |

It prefers well-draining soil, and it does require regular moisture — the plants will go dormant if conditions are dry for too long.

You can plant seeds or divide existing plants by digging up your neighbor’s tubers.

Add a general-purpose fertilizer in early spring, and then feed once a month during the growing season if your soil needs a little boost.

Rust Be Gone

These plants are fairly pest free, but their foliage can be affected by rust.

Safer Brand BioNEEM Insecticide and Repellent

For rust, remove affected foliage and treat the remainder of the plant with neem oil, such as this product from Safer Brand, available via Amazon.

Time to Reminisce Over Dinner

Whether it’s eleven o’clock or one o’clock, or yes, even four o’clock, there’s never a bad time to plant these colorful beauties.

Order seeds or ask a neighbor for a “passalong,” and help to revive a plant from an earlier time that surely deserves a comeback.

Four o'clock adds color and charm to the garden |

Invite Grandma over for dinner some summer day, and prepare to be regaled by tales of how she grew these memory-instilling flowers in her own garden.

Do you remember four o’clocks from your childhood? Do you have some growing in your garden now? Tell us your tales of this well-loved antique in the comments section below.

Don’t forget to Pin It!

I have tried to grow four o’clocks in zone 3. They will not germinate. My friend in zone 8 has the same issue. Are there any tried & true tips to planting these?

I remember them in our yard as a kid 40+ years ago. I noticed the seeds in the packet look different from the round peppercorn-like seeds I remember falling off the plant. Must be the extra moisture in the fresh seed. I’ve never tried to grow them until now. I just want to see something new out on my balcony. I’ve grown Morning Glories and Moonflowers and grape tomatoes. I wanted another kind of trumpet flower that didn’t climb, but grew as a bush.

I finally got these to grow this year, by putting the seeds into a zip lock bag with a damp paper towel. Put the baggie in a warm dark place (drawer, cabinet over the stove). As soon as you see the sprouts, put them in soil or potting mix. Magic!

My uncle in ND has been raising 4 o’clocks for 30 years.. Some of you may be shocked to see this photo but he has rows like this…it’s amazing…. I collected seeds from various colored plants just to see if I could get a specific color. I can’t believe germination is a problem for some. I have always been able to grow them… just NOT like his. He is in hospice right now at 94, I am trying very hard to follow all his instructions to try and grow them tall as hedges like he does… time will tell.

I purchased a home in March. Four o’clocks starting coming up in June and are approx. 2.5-3 feet tall now and almost in bloom. I didn’t know what they were for months until seeing the buds, and my sister in law took a snapshot and uploaded to her phone and identified it through a plant database. There are approx. 10 plants that line a spot near my back patio where I already have jasmine growing nearby. I can’t wait for the fragrant flowers and am soooo grateful for this lovely gift left for me! I’ve never had four o’clocks before.

My grandpa grew these along his fence line when I was growing up. When we would come over he would have us collect the seeds for him. He died about 45 years ago but we have kept the seeds through the generations. Our family now numbers over 300 and plants from grandpa’s seeds are growing throughout the U.S. and even in Europe! Looking at their little tie-dye flowers brings back many fond memories!

Thought I wouldn’t be growing a Four O’ Clock bush this year, since I didn’t start any seeds indoors this year. After I cut the bush back last fall, I ignored the pot (that sat on my balcony through the winter) and just let the soil stay in it. I intended to dump it and plant something new. Maybe it got enough water from the overflow when I’d put smaller plants in the pot and water THEM. In April, a new plant popped up from where the bush grew last year! Started watering it, and it’s now a foot high!… Read more »

Me and my husband moved into an older house that was built in probably the 40s. I picked up some 4 o’clock seeds and just threw them anywhere i could think they would look good. Mainly for the reason that i thought they would be a perfect match for this house cause they’re kind of considered a old timey flowerer. They’re just the beginning though.

I suspect it was a contaminated bag of mulch I used when re-planting the bed with a mixture of ferns, philodendron and lilies of the Nile.

This plant magically appeared in my garden last year – must have been a stray seed or two that wandered my way. My soil is lousy and this summer has seesawed from torrential rains to near drought, (Northern Virginia, near DC) but it has thrived and spread like mad, and has been flowering steadily from early June to late August. I probably shouldn’t tempt fate, but I plan to dig up the tubers this fall and try to organize them a bit.

I’m in zone 6b, Luray, Va. I was not aware of four o’clocks while growing up, but a friend recommended them at least 25 years ago, saying that they are poisonous to Japanese Beetles. I’m still not sure if the bugs are killed, but the plants are beautiful and reseed abundantly without any help. Just like marigolds, unwanted plants are very easy to pluck out. Mine are all yellow and grow to ~3′ tall. I never water or fertilize them.

Hi Connie!
Thanks for your comment and question! Sorry we are slow getting back to you!

These plants are tender, so if planting them outdoors from seed, plant them at the same time you would cucumbers and squash – after your last spring frost.

4 O’Clocks can grow 2-3 feet tall, so if you plant them in flower pots, you’ll probably want to choose some larger sized pots – or choose shorter varieties which would do better in containers.

Let us know how your container growing project goes – we’d love to see photos!

Next, make sure you harden them off before planting them if you just brought them home from a garden center. Start them off outdoors in a protected location – not too sunny or windy – and then gradually increase exposure to direct sun.

That depends on where you’re gardening, Theresa. Four o’clocks grow as perennials in warmer areas, and they will come back year after year in Zones 7b-11. They also reseed readily, so as long as they are allowed to go to seed, new plants should pop up in the spring in cooler zones as well.

Ugh, Martha, I hate this for you and your four o’clocks. Since you said you didn’t see bugs, I think you can rule out aphids.

You didn’t say if you saw any discoloration on the leaves. If you did spot some small flecks that form sort of a halo of yellow that then browns before your leaves started to wither, that could be leaf blight.

Planted from harvested seed that I got from a yard that was about to be mowed down & put them in a big planter last autumn. This spring, they grew tall & lush. Now it’s August, and not one flower head. No flower heads, no blooms. They get sun & rain, & Miracle Grow once a month.

Hi there! When plants that are supposed to flower or bear fruit fail to do so but instead grow a lot of lush foliage, it usually means they are getting too much nitrogen fertilizer.

If I were you, I would stop the Miracle Grow and see if that helps!

My ‘Maribilis’ four o’clock is so huge every year, I have to stake it up and cage it. How can I keep it shorter? It is at least 6 feet tall and about 4 feet wide. Can I trim it back or divide it and transplant it?

Hey Sandy, that’s a big plant! In spring, you can pinch back the main stems to promote more flowers and maintain a more compact size.

Or, if they start to get a bit leggy and ragged by midsummer, cut them back by about one-third to refresh them and encourage a second wave of flowers.

Thanks for your question!

Hi Fula,
Four O’Clocks are tender plants like tomatoes – they aren’t frost hardy. So plant them a couple of weeks after your last frost in spring. For Vancouver, Canada it looks like that is approximately March 28, so you should be able to plant these in Mid-April. Just make sure to delay your planting if it looks like you’ll be having any late freezes.
Hope this helps!

I remember having a stand of Four O’clocks outside of my bedroom window when I was a child. My Mama made me take a nap every afternoon which I always resisted. She would tell me I could get up when the Four O’Clocks bloomed. I need to get some. They were such a pleasant memory.

As a little girl, I remember our old neighbor and she would invite me everyday to see her plants. When she died, she left an impact in my life. As a grown woman myself, I planted them and always remember Grandma Dolly.
