Stokesia laevis (Hill) Greene, Erythea 1 3 1893. (Syn: Cartesia centauroides Cass., Carthamus cyaneus Banks ex Steud., Carthamus laevis Hill,  Stokesia cyanea L’Hér. [Illegitimate]);
 
Stokes’ Aster, Stokes Aster, Cornflower Aster;
 


Stokesia is a monotypic genus of flowering plants in the daisy family, Asteraceae, containing the single species Stokesia laevis. Common names include Stokes’ aster and stokesia.[2][3]  

The species is native to the southeastern United States. 
The flowers appear in the summer and are purple, blue, or white in nature.[1]  
The plant is cultivated as a garden flower. Several cultivars are available, including the cornflower blue ‘Klaus Jelitto’, ‘Colorwheel’, which is white, turning purple over time, and ‘Blue Danube’, which has a blue flower head with a white center.[4] More unusual cultivars include the pink-flowered ‘Rosea’ and yellow-flowered ‘Mary Gregory’.[5]
Like a few other plants (such as some species of Vernonia), it contains vernolic acid, a vegetable oil with commercial applications.[6]The genus is named after Jonathan Stokes (1755–1831), English botanist and physician.[1]

Any idea about the family ?Asteraceae (Compositae)‎ ?


Yes …! Stokesia laevis (Hill) Greene !


This was in my mind for so long for not being identified despite unique calyx.

Garden Flower for ID-131109-RK: Attachments (1). 8 posts by 4 authors.
Please ID this flower. Pic taken in Lalbagh Nursery-08-11-09.


For me it is Centaurea cyanus, the Corn flower, Bachelors’s buttons, blue bottle, ragged robbin.


It is Cornflower.


Stokes Aster (Stokesia laevis) and Cornflower (Centaurea cyanus) are two very different plants. It is interesting that this close-up picture makes the flower look similar to both the species.
Cornflower flowers are borne on tall slender stems typically 3 ft tall, and the flowers are about an inch across or slightly more.
Stokes Aster, on the other hand, is a pot plant, growing only 1-2 ft tall, with large flowers 3-4 inches across.
Maybe another picture of this flower, by …, will help.


… is right. Cornflower is v. different!


Yes …

Perhaps there is no need for another upload
It is Stokesia laevis

A cultivated, garden plant seen at the Lalbagh Nursery on 24/11/13.

Family Asteraceae.


Perhaps Callistephus chinensis


Thanks for resurfacing my post and a possible id.
Could this be Stokesia laevis as in flowersofindia, common name Stokes Aster?


You may be correct,

Stokesia seems to be closer than Callistephus


Appears to be same as available at efi page on  Stokesia laevis


Thanks for the link.
It appears to be the same.


Stokes’ Aster, Stokes Aster, Cornflower Aster ‘Blue Danube’ (Stokesia laevis).  … is right.  Check this link :

I have recorded as asteraceae weed in Nashik. in Agriculture fields. Finding difficulty in identifying. Please let me know the confirmed ID
My guess is Lactuca sp
Prostate Herb
Irrigated black soiled field
growing in shade
Picture 4th Dec 2018
Place Nashik city


Do you also feel it is some lactuca sp??


I don’t think it is Lactuca sp.


Please check in the genus Cichorium in eFI.


Leaves look different. 


Any chance it could be a Stokesia that has escaped cultivation?


I guess … is close.


I also agree with … id as Stokesia. To me appears close to Stokesia laevis as per details and references herein.
Appears some what distorted and not in its prime, for some reason.


to be definite one would need at the least an open flower with the centre showing. until then its a “likely” id
