Native of: s South America; naturalized in N. America; widely cultivated

Cleome hassleriana, commonly known as spider flower or spider plant,[1] is a species of flowering plant in the genus Cleome of the family Cleomaceae, native to southern South America in Argentina, Paraguay, Uruguay, and southeast Brazil.[2]

It is an annual growing to a height of 150 cm (60 in), with spirally arranged leaves. The leaves are palmately compound, with five or seven leaflets, the leaflets up to 12 cm (5 in) long and 4 cm (2 in) broad and the leaf petiole up to 15 cm (6 in) long. The flowers are purple, pink, or white, with four petals and six long stamens. The fruit is a capsule up to 15 cm long and 3 mm (0.1 in) broad, containing several seeds. Flowering lasts from late spring to early fall.[1]
C. hassleriana is commonly cultivated in temperate regions as a half-hardy annual. Numerous cultivars have been selected for flower color and other attributes. The “Queen” series includes the cultivars ‘Violet Queen’, ‘Rose Queen’, and ‘White Queen’. The cultivar ‘Helen Campbell’ has gained the Royal Horticultural Society‘s Award of Garden Merit.[3]
Plants in cultivation have at times been misidentified as Cleome arborea, C. pungens or C. spinosa.[2]

Cleome hasslerana.  Synonym:Cleome houtteana, :Cleome pungens, Cleome spinosa. The cleome, or spider flower, is an annual flower known for its long seedpods. They develop below the flowers to look spidery.  Most attractive cultivated annual in different hues (white, crimson, pink, etc. flowers).

I will upload the photos recently taken in Mysore.

–  am sure it is Cleome hasslerana.  Synonym:Cleome houtteana, :Cleome pungens, Cleome spinosa. The cleome, or spider flower.

I have grown this plant myself.

Please check the references:   www. toptropicals.com, www.davesgarden.com and many other websites as well as horticulture books.

–  … me too believe it to be Cleome hassleriana … presently known as Tarenaya hassleriana (syn. Cleome arborea, Cleome hasslerana, Cleome houtteana, Cleome pungens, Cleome spinosa)

We almost always had it during Ganesh festival and were used during evening …
It has in interesting pattern when the bud opens in to flower. A separate picture shown.

This is a species of Cleome (spider flower).

Please check for Cleome hassleriana ?

…, perhaps Cleoserrata speciosa.

I am not aware of the difference(s) between Cleoserrata speciosa and Cleome hassleriana. … to me look-wise the former is all pink and does not seem as striking as hassleriana.

Thank you … I can only add (about the colour) that the flowers that I have photographed last about 3-4 days and as they become older the petal color fades.
Then petals fall off one by one.

Thanks … It is quite possible. Cleoserrata speciosa. was earlier known as Cleome pentaphylla/ Gynandropsis grandiflora.  Link https://indiabiodiversity.org/species/show/278412.

Difference between the two is hairyness of the sepals.

I was not aware about all these nuances at the time I took the photo.  However I feel the sepals in the flowers I shared are not hairy.
My memory (a little old) and the zoomed in photos suggest that.
2 images.

Cleome hassleriana sepals are glabrous. I mean do not possess hairs.

Cleome speciosa from Gori Valley Area Uttarakhand

Beautiful flower! More importantly, it is not listed in checklist of flowering plants of Uttarakhand. Should be a new addition to Uttarakhand.

Cleome speciosa
seems to be naturalized at many places in India.
It must have established itself as garden escape initially.

I have observed it at the entrance of Kudremukh sanctuary.

It is growing gregariously in Mulshi on way to Lavasa near Pune. near human habitations.

It may become a weed..

One more new thing learned on this forum in last few minutes is that the correct name on GRIN seems to be Cleoserrata speciosa and Cleome speciosa is its synonym

Attached is a picture of Cleoserrata speciosa captured at the Jijamata Udyan flower show in Mumbai in February 2013.

Requested to please confirm ID.

It looks like Tarenaya hassleriana to me.
Please check if the sepals are glabrous (T. hassleriana) or glandular hairy (Cleoserrata speciosa).

Thank you for your feedback, I have attached a cropped version of the same pic.
The sepals seem to be slightly hairy, therefore this may be Cleoserrata speciosa..

Could you please confirm?

Thanks for the close-up picture of flowers. Yes, your ID Cleoserrata speciosa is confirmed now 🙂

has to be garden escapee

not native of this part of the world

I guess so …

The sepals are glabrous (Tarenaya hassleriana) or glandular hairy (Cleoserrata speciosa);

So it may be Cleoserrata speciosa.

These are taken at a different location in Muscat.
Cultivated plants seen on 24/2/17.
Both colors pink and white.
Is it possible to validate?

if read … thread and look at the illustrations there are links in his writing, you will get a lot of insight
those illustrations show that side views of the inflorescence and preferably whole plants are necessary.
the differences become very obvious then.
do you have more pictures?

better info to add to all the discussions
see … response in this thread: https://mail.google.com/mail/….Th

Though insertion point of stamens are not clear, first should be Tarenaya hassleriana & 2nd should be Cleoserrata speciosa based on stamen colour and colour of the petals.

Both the pictures were taken at the same location, same time.
That’s the reason I posted them together. Thanks for the suggested ids.

cleome alright

efi page on Cleome gynandra (Syn. Cleome pentaphylla L.; Gynandropsis gynandra (L.) Briq.; Gynandropsis pentaphylla (L.) DC. ….);

It is not cleome gynandra;
Cleome burmanii has 6 stamens like c. gynandra, flowers are pink, but gamble noted that the leaflets are 3 only, but here the leaflets are 5.
may be another variety or species

For me the ID looks correct. Wikipedia mentions it as Cleome hassleriana

According to both WFO and POWO correct name is Cleome houtteana Schltdl (Syn: Cleome hassleriana Chodat; Tarenaya hassleriana (Chodat) Iltis)
