as per Catalogue of Life;
Moss-rose Purslane or Moss-rose, Time Fuul, Time Flower, Portulaca • Hindi: Nonia नोनिया • Manipuri: Pung mapan satpi • Urdu: Gul-e shama गुले शमा;
Most species of Portulaca generally flower and stay open till noon, remain closed before and after that or on a cloudy day
Also very easily propagated from seeds and cuttings.  
Flowers are very beautiful and the cultivation of it is also very easy if it gets lots of sunlight. It can be grown in a hanging basket also.  It is very good for hanging pots and should be kept in a sunny location for good flowering. 

I am uploading the photographs of a Portulaca, which after a lot of investigation turned out to be P. x Yubi. Some consider it to be a variety of P. oleracea, others a variety of P. grandiflora and still others as a hybrid between the two species. This seems to be a good material for any one interested in Biosystematic or Molecular studies.

Can anyone identify the this flower please?

Portulaca grandiflora, cultivated in many colours.



also portulaca: This plant I collected in Apulien (Puglia, South Italy), last year. Now it is glowing in my house. I looked in my Apulien-collection and found the Fotos 100_9494-k and 100_9486-k. The other three with prefix Apulien are from my hause, brought from Apulien.
Are these Portulaca. A don’t have a foto of the flower from front.

The first three photographs perhaps belong to Portulaca grandiflora. The fourth in circular bed has Portulaca in the upper half and Aptenia cordifolia (with broader leaves) in lower half.

Now I shall wait to see the flowers of Portulaca here in my house.
I have also brought a cutting of the second plant in the circular bed Aptenia cordifolia and is doing well here in Ritterhude. Does not have flowers yet. Flowers from Apulien in a separate mail. Is 100_9494-k also Purtulaca grandiflora?

Looks like that only.





Portulaca: One of the few multi-coloured flowers which blooms in summer. Hardy but withers in a few hours. Also no life as cut flower.

commonly called as China rose.
dont know why?
i had seen them in magenta and white as welll as both mixed colours. not so many.
Of course Portlica i have seen in all these colours 

Portulaca grandiflora
I know about these names, but wonder if it is called as China rose (Hibiscus rosa-sinensis
eleven-o’clock, Mexican-rose, moss-rose, rose-moss

.., In my school going age local gardener also revealed me the name “Cheeni Gulab” for the same flower. But as a botanist I came to know the “Cheeni Gulab” is not the “China Rose“. “Cheeni Gulab” is eleven-o’clock, Mexican-rose, moss-rose, rose-moss and “China Rose” is Hibiscus rosa-sinensis. Here also laymen call Portulaca grandiflora as “Cheeni Gulab” in hindi and “China Rose” in English 

beautiful flowers. These flowers are also known by the name “Office time” as the flowers usually  open at 9.00 a.m. and closes at 5.00 p.m. 

in our chilhood, we used to call it 4 o’clock flower….our nuns teachers said that’s what it was, it closed promptly at 4 pm in Calcutta, in our school gardens…. go figure!!!

Yes .. Portulaca grandiflora we called this “DIN KI RANI” locally 

And eleven-o’clock plant because the flowers open around that time. That is true also of some other species of this genus. Last year I remember, there was some confusion about the colour of flowers of Portulaca quadrifida, my colleague saying it has reddish flowers, whereas I knew it with yellow flowers. We collected the plant at 8 a m when it had only buds which looked pinkish. We brought to to College, kept in the lab in sunny area and asked
the lab attendant to inform us when it first flowers. He came running to me just at 11 a m informing that it has flowered, and we saw open flower with yellow petals. 

In South India some varieties ( those posted by ..) of Portulaca are called “table rose ‘. Mirabilis jalapa (Nictaginaceae) is commonly called 4’o clock  plant, because the flowers open in the evening. The plant comes in different hues and very common in Mysore city.  They grow even wild and there are a few varieties growing in my street. 

yes, aren’t regional differences interesting…. 
Mirabilis jalapa is called SONDHHA (as in Sandhya) Maloti (as in Malati) in Bengali,  I have them growing wild/naturalised all over the south calcutta unkempt places.. and some have invaded my lawn (which is not unkempt, by any means)… though I must admire its scent… it becomes a nuisance, produces zillions of large black seeds….. I have also grown them in my  apartment balcony in  different continents,  both yellow and deep pink/magenta , they must hybridize very easily, because the seeds I saved for the following summer grew pink and the combination as in pink and yellow striped variety only…. no yellow flowers ever came up for a few years in succession… I recently saw miles of linear collection, as in growing along narrow stretch of soil along footpaths along the ganges /Bhagirathi near Murshidabad… all yellow… no pink….not a single pink flower….

any small version of a fruit or flower is calld chinia or chini in Hindi. Chinia kela. In the same way probably because of its size and resemblance to rose in appearance at least, portulaca is called chini gulab.
This is my guess.




Flora of Panipat- Portulaca grandiflora from Arya College campus: I think this plant is widely used as a garden decor 




efloraofindia:”For Id 17082011MR1’’ plant with magenta flowers at PUNE: Kindly identify the plant with following specifications
Date/Time- March/April 2011
Location- Place, Altitude, GPS- Pune Maharashtra

Height/Length-  short plant 5-6 cms I think
Leaves Type/ Shape/ Size- thin green strips
Flowers Size/ Colour/ Calyx/ Bracts- Deep Magenta flowers
Fruits Type/ Shape/ Size Seeds- Not see

… most probably cultivar of Portulaca grandiflora, native of South America … commonly known as Chinese rose, Japanese Rose. 

In Marathi the local name here is Chini gulaab but I wanted the correct identification. 

This plant has recently beeen discussed at length here ,,,, see this link:




efloraofindia:”17102011MR3’’ Porticula grandiflora Pune: Sharing pictures of Porticula grandiflora just bloomed at my place at Pune 

I think you meant to say Portulaca grandiflora. You are right
Family : Portulacaceae 


Portulaca grandiflora: Seen at a Plants exhibition.  Commonly called  “Office Time
Place : Byculla, Mumbai
Date  :  19.02.11
Habitat : Cultivated 

we call it 9 O’ Clock. 

Yes it is also called 9 O’Clock flower as the flower buds opens during that time. 

It would be interesting to know the source of your information. Portulaca grandiflora is generally known as *eleven-o’clock flower *as per GRIN information.  In Vietnam, it is called “Hoa mười giờ” meaning “Ten o’clock flower“, because the flower is usually in full bloom at 10 o’clock in the morning (as per Wiki: http://en.wikipedia.org/wiki/Portulaca_grandiflora. Most species of Portulaca generally flower and stay open till noon, remain closed before and after that or on a cloudy day.
    Once I remember having disagreement on the colour of flower colour, my colleague saying it has pink flowers whereas I knew it with yellow flowers. Next morning we plucked the plants at 8.30 a m when all were in buds pink in colour, brought them to College, and put it in beaker with water on a window with sunlight and asked the lab assistant to report when it comes to flower. He came running to me to me after some time to report it has just flowered. I saw my watch, it was 11 a m, and I saw the flowers they were all yellow……It was Portalaca quadrifida

And yes, I forgot to mention, new cultivars of Portulaca grandiflora have been developed that remain open for most of the day.

Thanks … for this interesting information that in various places the timing is different for its opening.  I like this plant very much as the flowers are very beautiful and the cultivation of it is also very easy if it gets lots of sunlight. It can be grown in a hanging basket also.

we called it 4 o’clock flower… that’s when they went to sleep… promptly…

we has a very long  conversation about potrulaca grandiflora before:….
its at this thread:

in our area 4’0 clock flower is  Mirabilis jalapa.  See how the name changes in different places !!




Portulaca grandiflora – Moss Rose:

Portulaca grandifloraMoss Rose of Portulacaceae family.

Flowers all throughout the day

Photographed from ATREE garden, Bangalore

These plants grow very well in Chennai almost throughout the year, as they need bright sun light. One can see varieties of these plants in Chennai. They are good during hot summer in Bangalore and Mysore.

It is very good for hanging pots and should be kept in a sunny location for good flowering. Also very easily propagated from seeds and cuttings.
