I love these plants. In my climate they have a wonderful late summer flourishing period. Right about the time most of the plants are dying out or going dormant, these suddenly explode up into small bushes replete with multi-colored flowers. Sadly, they do not have a scent here but they are beautiful. They produce generous amounts of seeds.

I've grown them from seeds and found that while they came back, they diminished. I've supplemented with roots and tubers, and with new plants. I also save out seeds and replant in the beginning of the year. At this time they are beginning to steadily come back and fill in the garden regularly.

They have lovely, full foliage of a cheerful medium green and the flowers are gorgeous shades of yellow, purple, pink, red, and... read more

Four O'Clock, Marvel of Peru (Mirabilis jalapa) are very invasive in my yard. The tubers are difficult to dig up and not killed by chemicals such as Roundup which I don't like to use anyway. The plants show up everywhere. The plants are beautiful and the blooms are magnificent, however.

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.

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.:-)

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 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 seeds...is 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 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!).

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. I now live in zone 7 and grow them every year from seed, and I am always so excited to see what color they will be. 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?

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".

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.

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... read more

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 f... read more

A great plant to have when you have extremely dry conditions which we do for many months.

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!

Ten Years ago, I spent a year working in Beijing, China. There is neither space nor really soil for the people to have gardens, but they had many pots and planters outside their small homes, and in them were 4'oclocks.
On my daily walk to the market, I would scoop up the seeds that had fallen from the flowers onto the sidewalk, take them back to my room and store them away. I brought them back with me to Boston, and every year since I have sown seeds and replanted tubers from the last season. My favorites are yellow with red stripes, and they smell incredibly.

I love the flower, and of course they are a live remembrance and souvenir of that incredible year.

Just a note. You do NOT have to tolerate tomato hornworms in order to have sphinx moths come to your 4 o'clocks. There are over 1200 species of sphinx moth of which the tomato hornworm is the larvae for only one. I don't know whether or not the adult version of the tomato hornworm would pollinate 4 o'clocks, but there are MANY MANY other species of sphinx moth that will do the job. Go ahead and kill off your tomato hornworms, you're not hurting your 4 o'clocks by doing so.

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.

To get sphinx moths in your area to thrive, do these 2 things:
1. Grow Four O'Clocks
2. And let tomato hornworms eat your tomato plants for awhile!

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.

We like our Four O'Clocks. They bring hummingbirds in the mornings and those big beautiful sphinx moths at night, the ones that look like hummingbirds. I suspect their summer garden fragrance is part of what makes them so popular.
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!

Ours were mixed colors, white, yellow, pink, and lavender. Lovely smell, very easy to care for. Great project for a child! My other son started snapdragons from seed, same brand of kit, with much less success.

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!
