Gardeners' Notes:

Positive Bear_with_me On Nov 4, 2014, Bear_with_me from Vancouver, WA wrote:

I really enjoyed growing Four O'Clocks this year, 2014. I obtained the seed via mail order. I soaked them overnight in water, then planted in seed starting medium on a seed warming mat. I did that because on the first attempt, just planting without warmth, only a few germinated. Using the soak and warm mat, germination was about 75% which was plenty.

I started them early, in April, for planting outside in mid May. The Four O'Clock plants were lush and bright green. The reached 18 inches to 2 feet tall and wide. The flowers opened about 6 or 7pm and remained open until about 10am in my cool summer night climate.

Deer, voles, and rabbits did not touch them at all. I have a big problem with those animals and need resistant plants. That is one reason I wanted to grow Four O'Clocks, as a front border to keep deer away from other plants in the flower bed. This approach seemed to work although deer did walk around them to eat some grape plants.

The yellow flower shows up best in the evening and early morning. All of the colors were nice. I also liked the red.

I saved seeds for next year. Marvel Of Peru is a historic variety, open pollinated. I saved seeds from each color, in separate envelopes. Most likely, they have cross pollinated and the colors will be unpredictable, which is part of the enjoyment.

I won't know until Spring whether they will perrenialize here. It would be fun if that happens, but they do so well from seeds, I don't mind if they don't.

I will definitely grow Four O'Clocks next year. They are colorful, resistant to herbivores, and trouble free,

Bentspur - hard to move for two reasons. The break easily at the knuckles on the stem and they form a tuber.

At the end of the season, dig the tuber and over winter indoors and plant next year where you want it. Assuming you live in colder climates. Not sure about down South where they are perennials.

I don"t plant many sends anymore - mainly just the tubers. Gives you several weeks earlier bloom over planting seeds.

Also - when you use the tubers you know exactly what the plant will look like.:-)

It's all personal choice, and I for one love this plant. In Tampa Florida they are so easy to grow in many colors. Flowering most of the year. I cut them when young a few times it seems to make the stalk thicker and therefore sturdier. When growing I take the two leaves that are directly across from each other and pop those ones off this way I get more of a full bushy plant. I have grown them so far up to 5' tall. They prefer morning watering and if real hot I give a light mist in evening. I do nothing special during winter and they have been here for four years. When the seeds drop on the ground another grows. I have a few where the stalk is over an inch in diameter, from me cuting it back. I don't follow planting guides myself thy never worked for me. I have learned my plants thru trial and error. I love my four o'clock s easy and pretty and very colorful! If they get to be too many, they pull up in a second then you have some for a friend! This has been my own personal experience. Oh almost forgot if I cut the dead flowers off I get triple flowers the next, and if I want it to have more branches to hold all the flowers I cut that branch just below a v point. Good Luck!

Regarding the "invasive" nature, it self-seeds in central Connecticut but certainly not enough to be invasive. The rootstock will also survive the winter if it's in a protected location but even then it's not reliably hardy up here.

Individual plants can certainly get quite large so give them some space; in return they'll be loaded with flowers until the cool weather sets in - around September in my location.

Rating neutral as I need more time to decide whether I love or loathe this plant. When I first got it, I was warned about it being invasive. I planted it last Fall in full sun, in an area easy to work in, should I find myself pulling seedlings all the time. Even with this knowledge, I was not prepared for the 100 or so seedlings I got from ONE plant the following spring. They were easy to pull out but right then I realized this was going to be more work than I wanted. So, after manually pulling every seedling I saw, I applied some pre-emergent and so far the seedling situation seems under control. (I try my best to use organic gardening methods, but I'm not above pulling a chemical gun when the thug merits it)

My plant is 5 ft tall. As for fragrance, I finally made time one evening to walk by the plant and it was indeed very pleasant, but I had to stick my nose in one of the blooms.

Last year's winter was mild so there was little dieback. My plant produces the bright pink flowers. I sowed some seeds of the yellow in an area where nothing grows and of the 25 seeds planted, only one appears to have germinated, we shall see...

I used to grow these all the time and I love them. They were the hot pink color and opened up every day between 2 and 4 depending on the temperature. We moved and I am now in my 3rd yr of a new house and garden and I am now growing some from seed. I have a question. A lady told me that the white old fashioned ones could not be grown from this true. I have never heard of this and was unsure. I would love any feedback on the white version. Thanks and happy gardening.

I live in Saskatchewan, Canada and Four O'Clocks do grow here. Started some by seed in June and had plants 2 feet and taller by mid-July! Covered in buds but only seen them open once on a cloudy day and once at 11:30 at night! They were in direct south sunlight all day. Just wondering if planted in shade will they bloom at all or not. I was so excited to see this plant grow so vigorously and then so dissappointed to never see the blooms. On the two occasions that I did see blooms they also had no scent unless you stuck your nose right in the flower!

These have been so beautiful that even my husband has liked and commented about the yellow color against the green color of the leaves.

I remember these beauties from when I was a kid. My mom had a plant at our front door. It got to be about two feet high, and no matter what time of day, was in bloom. Living in Philly, I have seen them in curb-side gardens -- again in bloom all day long. I started my seeds indoors the beginning of April in a hanging basket that had a coleus in it from last year (which came back again this year and is HUGE!). I placed the basket outdoors the middle of May, and the four o'clocks have grown to the size I remember as a kid. I have yet to see an open bloom. They are in direct sunlight for about 5 hours a day, and have plenty of buds, plenty of flowers which look as if they have bloomed and closed, and a few spent flowers on the ground, but have yet to see any fully opened. I even stayed up until 2 in the morning to try to catch them in bloom -- but no dice. I have a place to transplant them in the ground, and hopefully they will come back next year, and hopefully with better luck with blooming. I'd like my neighbors to enjoy them as much as I do!

When I was a little girl, I used to collect the seeds with my neighbor chum. I was enchanted with them from that point on.

They do well for me, produce tons of seeds (just wait till they turn black and pick them!) and the flowers are so pretty. I am going to start saving the tubers this year, as the seeds don't often come true to color if planted in a mixed color border. 4:00s. Ah, what's not to like? :)

I have white, yellow, light pink, magenta and yellow. I'd love to trade for a couple of colors I don't have.

About 15 years ago, my mom gave me seeds for both the magenta and the light yellow four o'clocks. As of this year, I have a hedge of flowers that is about 5 feet high in places. Nothing else would grow in that spot, but the four o'clocks love it! The foliage dies back with the frost, but returns with ever-increasing vigor in the spring. People in the neighborhood have commented about the scent - it is so strong that they can smell it as they walk by on the sidewalk. In the last two years, some white ones have blossomed in the midst of all the magenta. Can anyone tell me how that came about?

Nottingham, UK. Sept 8 2010

This was purchased with the assumption it was "lily of the valley" !

We planted 3 tubers in a large pot about five months ago and were amazed at what came up. We have two yellow plants and one white plant.

There is hardly any aroma and the flowers seem to open on some kind of shift system. They are all closed between 1.00pm and 3.00pm but open at varying times outside this window.

We have noticed the seeds and are wondering whether you pick them off or they are "thrown off".

We are so glad to have found this site and are thankful for all the comments. We feel that we can now manage the plant
rather that let it just do its own thing.

Thanks again, hopefully we'll report back next year on how we got on.

We live in a beautiful hardwood hammock, with the land around the house cleared to a certain degree. A friend from Havanna, FL gave me a plant from her garden and I planted it in Crawfordville, FL where I live. Originally, I planted these near my foundation, however I learned that the tubers can get to be extremely large; so I moved the ones I had out from the house to the woodland borders. Our soil is a sandy loam (caused by the leaves from the hardwoods), but not very rich. I threw seeds into one area (which I call "the garden of weeden") a couple of years ago and I am shocked by how beautiful this plant is. We mow where we don't want weeds etc. every couple of weeks, so I don't anticipate these getting too out of hand. However I'll keep everyone posted.

The contrast of the magenta pink to the green foliage is totally outstanding. And since they are a night bloomer I am even more interested in investingating the white varieties.

I planted about 20 seeds last year. It was an assorted packet, with variegated, yellow, red, and orange and even one or 2 blue ones. They all opened, were about 3 feet tall, and flowered continuosly till frost, even with out cold, wet summer last year. They were in FULL sun ( about 8 hours a day), and planted in sandy soil.

We had a failry mild last winter ( im in zone 3B-4B it varies here), which was about a zone 5B winter, with one or 2 days at -28C at night. Our spring has been very mild.

I dug up all the beds, removing last years dead foliage, and tubers from the 4 oclock, heavily raking the soil, and addign another few CM of top soil.

Having planted my Canna, and the other beds, I was weeding today, and to my suprise, my 4 oclock has self seeded, and so far 1 seedling is sprouting. I had no idea it would self seed this far north ( NW Ontario). Now im just wondering what to do with it ( or them if there are more).

I had no experience with fragrance, but the plant grew exremely fast here, and even though I am not a big fan of flowers, these are a nice addidtion to your garden.

This is one of my favorite plants that I've ever had. I don't even understand the "Negatives" that people have posted on here.

I remember growing this plant years ago when I was in middle school and high school--back during the days that I first became interested in learning about plants and growing them. So, it was a nice surprise to find a four o'clock bush growing in the garden of the first home I purchased, back in 1996.

I was surprised to see it come back each spring--in my younger experience (which was in a much colder climate) it grew strictly as an annual that had to be re-seeded every year. After living in my 1996 home a year or two, I found I needed to move the plant because of remodeling and adding a deck to the spot where it was growing. When I dug it up, I was very surprised to find a HUGE tuber! Prior to this I'd never known these had tubers before! The immense size of it (not carrot shaped like some here have written, but more of a lateral small-watermelon shape) made me wonder how long it had been growing there. We'd bought the home from a 96-year-old widow who'd lived there since the house was new in 1925. I like to think she had cared for this plant for many, many years.

Anyway, it successfully survived the transplant to another spot in the yard. So, when we sold the house and moved to another in 1999, it was an absolute "must" that the four o'clock come with us. It has been here at our current home ever since! Each year it faithfully forms a large bush, covered with INCREDIBLY fragrant dark pink blossoms. Anytime someone comes over, I pick one or two of the flowers and hold them under their nose. They are always astonished at the powerful fragrance. I love to sit on my front porch in the evenings and smell this wonderful plant.

Each winter it dies back, with no sign of the plant at all. But I'm always confident of its return in the spring. NEVER have I had a single problem with having to weed any seedlings from it.

If I ever left this house and could only take one plant with me out of the multitudes I have growing in gardens all around the house, this would be the plant.

Neutral dreamlayers On May 8, 2010, dreamlayers from Windsor, ON (Zone 6b) wrote:

Only one seed germinated from the first seed packet. The second seed packet had a good germination rate. I guess this may have been due to soil temperature, because all seeds germinated around the same time, when warm weather arrived.

Early on, I lost one or two plants from stem rot at the base, maybe from overwatering. However, the rest were healthy, and they grew quickly and without any problems. They quickly outgrew their pots. When they got big, they could support themselves well, but they were vulnerable to storms, so I added some stakes.

The flowers started soon enough. Unfortunately, they did not open in the late afternoon as I hoped. Most opened around sunset (like evening primrose) and the red ones never fully opened. The flowers only opened fully in daylight during the cool days of early fall. The smell was very nice, but not especially intense.

I let the frosts kill the foliage outdoors. Then, I moved the pots into the garage before it got very cold. I also dug up two roots and stored them in garage. All of these plants died. All the roots left in the ground also died. Im now growing new plants from seed I collected last year.

I had one appear from one of those mixes of various seeds. It grows on the south side of my house where it gets shade probably half of the day. I noticed I had 2 of them this year, after probably 6 years. So at least where mine are at, they have not been invasive. After reading these reviews, I'm hesitant about trying it out in my garden which gets full sun. It sounds like they could be a little too successful, like my borage. (That self-sews so prolifically I'll never be without borage, whether I want it or not). I thought I'd mention that mine are perennial, growing from tubers, even though I'm in zone 5b/6a in Missouri. I'm guessing this is due to a warm microclimate up against the house on the south side. I'd be surprised to have them come back from the root out in the unprotected garden. I'd probably rate my experience as "positive" except that mine are not fragrant at all.

These plants flower summer through fall, where they are irrigated, in our garden. The established, non-irrigated Mirabilis jalapa burst out of the soil with the fall rains, and then bloom until the frost. Our mother plants came with the house and are probably about 25 years old. Seeds are true to color, generally cerise or yellow, a few white, and one yellow-splashed-with-white. Gophers do not bother the huge beet-like root tubers these plants develop. A couple words of warning: if you are not sure you want them forever, plant them in a container; if you don't want them to spread, plant them at the bottom of a slope--never the top!

I've struggled with a wooded lot for years. This year I just kept to basics, hostas, rug junipers, and four 0'clocks which grew under the front window of my house when I was growing up.

So I purchased seeds from 2 different companies and I have the basic colors, red, magenta, white, yellow, and pink. I seeded in rows, and placed garden cloth between the rows to keep down weeds and to achieve some order. I mulched over the cloth to give an attractive appearance. In the center, I placed a whiskey barrel with a shepherd's hood for 4 bird feeders. Three sides are lined with hostas. The background is a dwarf fringed red leaf maple.

For variety I have magenta petunias in the whiskey barrell and rows of biannuals between the rows of 4 0'clocks. I planted the biannuals by seed so there are no flowers but just wonderful foliage this year which looks awesome with the profusion of four o'clock blossons. Although the design is formal, the four o'clocks give it a real homey look. As I write this a hummingbird is looking for an open 4 o'clock blossom.

Maybe any plant looks great when you showcase it like this, but for me, the success with the four o'clocks gave me confidence to begin another project in a difficult setting.

Four o'clocks are so easy to grow here in Massachusetts, I don't know if I need to dig out the tubers. I can simply plant seeds again and get a marvelous result. We'll see.

The yellow form seem to be the most stronger one- I keep getting more and more yellow every year - the main problem is that they have weak stems and have a bad habit of flopping over if not supported - they tend to shed seeds by the tons - they look like bullets - about the time of frost or late fall when you start removing the plants check the ground around them, or beat the plants against a solid surface to try to loosen the seeds. The tubers also can be storaged in the house - they have low disease rate (if any during the winter) - don't worry if you break the long thin taproot - it's easier to put in the ground anyway - I usually dig down only about 3 to 4 inches deep, even laying the tubers on the side and it will grow easily into a new plant the next year.

Clearly in warmer climates they are too invasive but in colder climate the winters will kill any you leaves outside.

I ADORE the plant.
I first planted it three summers ago, from bought tubers (said to be annual).
Even though I don't have a garden, I just wanted to give it a go as a pot plant, on my balcony.

Well, it worked magnificently. The "matriarch" - the plant that got more space (= a bigger pot) than the others - has grown full size (almost a meter high) and is now the lushest of them all. For three summers now has my otherwise typically Central European balcony ;) been a luxuriant cascade of white, yellow, white/yellow, pink, pink/white (the pattern of the two-colour combinations is striped and/or "freckled"), and, of course, deep red/purple flowers. (I have also planted some seeds of a gorgeous ORANGE variety, but it seems to have been "overrun" by the nearby red-flowering plants.)

I especially adore their heady yet sweet, sensuous yet tender scent.
In fact, it has become one of my favourite smells in the world.

In the winter, I simply cover their semi-exposed "roots" (bulbs) with a special plant-covering textile (the kind you can get in any store) or a few fir branches. If the winter is very dry, I water them - very moderately - perhaps once a month.

But, if you don't mind, I also need urgent HELP.
A few days ago, the "matriarch" plant opened its flowers, much to my delight (the others usually start flowering a month later). I inhaled with great pleasure its sweet smell, although I had the impression it was slightly less intense than the previous years. Still, it was her first flowering night, so I gave it little thought.

But yesterday, and again today, I have noticed, to my utter dismay, that the flowers have LOST THEIR SMELL. Totally!
How is that possible?
Can anyone, please, advise me?
There are no special conditions this year: the weather is hot, mostly humid, they are properly watered, they don't seem to be plagued by any pests (highly unlikely in M.J. anyway)... What is the matter?

I would be really grateful for any advice!

P.S To KELL and/or anyone else who might have uprooted the tubers by mistake: just put it back (and, if you're like me, say "so sorry!" ;)) and forget about it. M.J. is INCREDIBLY sturdy and resistant. It'll grow.

The same goes for any seeds that failed to grow this year.
Don't give up on them. In all likelihood, next year you'll be overwhelmed by an ocean of M.J.!

We have also found that four o'clocks kill Japanese beetles. Every year around July we find a few chewed leaves and a bunch of dead Japanese beetles underneath. A real plus.

I didn't like these much. On the plus side, they do form a nice substantial bush, with more substance than most annuals (at least they are an annual for me up here!). They bloom for a long time. The flowers are nice and bright when they are open.

The main minus for me is that the dead/fading flowers remain on the plant - there are literally hundreds on the plant at any one time, many more dead flowers than fresh ones, and the overall impression is just yucky. Also, the flowers are open only for a brief period in the afternoon - the plant does not look so great when they are closed. There was no detectable fragrance. The colors are not my thing either - very harsh tones. I just hope it doesn't reseed too badly on me!

We saved a handful of seeds, and I am anxious to see if the original plants come back. I'm glad I found here that they can be invasive. I think we'll stick to planting them in containers for now!

If you have unlimited space and want a plant that self seeds, grows large and needs no care at all, plant them. But if you live in a warmer climate, like order and have limited space, DO NOT PLANT THESE!!! They take over and cannot be killed. Once you have them, you have them. I pull them and pull them and pull them. I can't dig them for I would have to dig up my whole garden, the tubers are so deep and far reaching.

It was so wonderful to see the other messages in the thread about four o'clocks and I just had to add my experience with them as I love the four o'clock a lot.

I was first introduced to the four o'clock when I was a little girl when my family and I were living in Houston. I loved their colors, and one of the plants we had had the flowers that were speckled. This one was with magenta as the main color with a speck of yellow on it. It was absolutely beautiful. I coud never understand why they were called four o'clocks until one day I was watching the clock we had and sure enough, at 4:00 in the afternoon the flowers were open.

I found out a number of years later when we went to visit my mom and grandma's home country of Panama one year (about 20 some years ago) and I found out that the four o'clocks grow there too.

I am in Jacksonville, FL now and about 4 years ago I decided to plant some of the seeds that I have and they have done real good even now. I do fertilize mine.

I found out the other day while doing a search on them that they are now calling the multicolored four o'clocks: "broken colors". A pic I saw on a website showed one that was like what another poster said, colors that made it look like peppermint candy.

I am hoping to get more seeds of white four o'clocks, try to get some red ones if I can as well as the salmon colored ones. Someone mentioned purple and I hope I can find some of them as well to add to my collection which includes magenta ones, and soon yellow.

I would love to hear from others in the Jacksonville, FL area that grow four o'clocks to see if some of them have the broken colored four o'clocks so I can see them up close and not just a picture.

The eaten seeds put me into a panic though, because I had no idea what the plants were called and had never seen them grown around here at all (and I only discovered this site recently). Luckily, a few seeds germinated where they had fallen in the flowerbed, so I was back in business. This year I tried starting a few them inside, but found that because they germinated and grew so quickly, that I had started them way too early.

In my area even though we do have hard freezes and some snow the 7ft tall one is from the original plant not seed produced, so mild winters make these perennials not annuals, as long as tubers don't completely freeze and rot. This 7 footer was transplanted here in Alabama from one grown in Oklahoma. Therefore they are hardy and you can grow from cuttings or from tubers as well as seeds.

I have grown Mirabilis jalapa (4 O'clocks) for 5 years now, always from seed I have collected from the previous year. I can not say enough good things about them. They have very rewarding blooms. Mine get 3-4 ft.tall and 2 ft. wide. They bloom in mid-summer and last through the fall. The blooms open around (you guessed it) 4 O'clock in the evening.

I sow them in the house before the last frost and put them out when they have 4 leaves. All I do from there is water & enjoy! As soon as the flowers begin to die, I deadhead them until September, then I quit and collect my seed for the next year. Do Not mulch until it's seeded if you want them to self sow! Mulch after it's seeded for winter protection. Hope I helped. ENJOY!
